Scanner® 2000 microEFM Section 1

Section 1—Introduction

The NuFlo Scanner 2000 microEFM packs the gas, steam, and liquid measurement capabilities commonly

available only in large instruments into a compact, low-power ow computer. The device is available in a CSA-approved explosion-proof and weatherproof model suitable for Class I, Div. 1 and Div. 2 (non-sparking) installations, and an explosion-proof ATEX-approved model suitable for Zone 1 installations.

A single lithium battery pack typically powers the instrument for more than a year, making it ideal for remote

locations where power supply options are limited.

The Scanner 2000 is an economical chart recorder replacement, stand-alone totalizer, and ow computer, all in one. It measures and computes standard volumes of gas, steam, petroleum liquids, and generic liquids with a high degree of accuracy. These measurements are typically based on the differential pressure outputs of an orice plate or a cone meter, or the linear pulse output of a turbine, positive displacement or vortex owmeter. This combination is ideal for the gas and water measurement associated with coal bed methane operations.

Combining the differential pressure and static pressure inputs of an integral MVT with a process temperature input, the Scanner 2000 offers everything needed for an AGA-3 or cone meter run in a compact, explosion-

proof device. Similarly, compensated liquid measurements can be obtained with an orice meter, cone meter, or averaging pitot tube meter (such as Annubar 5167, cone, or averaging pitot tube calculation methods.

) installation, using ow calculations based on AGA-3, ISO-

Alternatively, the Scanner 2000 can be paired with a pulse output gas meter to obtain gas measurements in

compliance with AGA-7 standards. Live temperature and pressure inputs and the AGA-7 algorithm allow computations based on gas turbine, rotary or vortex meters.

When liquid measurement is the goal and pressure inputs are not required, simply purchase the Scanner 2000

without the MVT and mount it directly to a liquid turbine meter, then install an RTD in the ow line for temperature compensation. The Scanner 2000 uses algorithms based on AGA-7 principles to give accurate measurement of API liquids and other generic liquids.

The addition of an optional expansion board expands the input/output capabilities to include a second turbine

meter input, enabling the Scanner 2000 to measure up to three separate ow runs, which could represent a gas measurement, water measurement and oil measurement. A pulse input, two analog inputs, and an analog output are also included on the expansion board.

Every Scanner 2000 microEFM is shipped complete with software for fully conguring hardware and ow calculations, calibrating inputs, and collecting and viewing ow history. With hardware and software included in the standard product offering, the Scanner 2000 microEFM is a complete alternative to the chart recorder.

Plus, because the Scanner can be powered by a lithium battery pack that is contained in the enclosure, the

installation cost for a Scanner 2000 is about the same as that for a chart recorder. High-speed communication

via industry standard Modbus

and Enron Modbus® protocols makes it easy to integrate the Scanner into other

measurement systems.

The Scanner 2000 is also available in a eldbus conguration that is powered by a eldbus network and communicates via Foundation™ eldbus protocol. The eldbus conguration supports many of the hardware options available for non-eldbus devices. See Appendix C—Scanner 2000 for Foundation™ Fieldbus, page

C-1, for details.

Measurement Canada has approved the Scanner 2000’s use for custody transfer applications when an optional

seal kit is installed. See Measurement Canada Seal Kit, page A-14, for details.

For a complete list of specications, see Table 1.1, page 14.

Flow Rate and Fluid Property Calculations

The Scanner 2000 calculates ow rates and uid properties for natural gas, steam and liquid ow. The following descriptions identify the industry standards upon which these calculations are based.

Natural Gas

The Scanner 2000’s natural gas calculations and data storage conform to AGA-3, AGA-7, AGA-8, API 21.1, and ISO-5167 industry standards. The ow calculations compensate for the effects of pressure, temperature, and gas composition to calculate the volume of gas measured at specied base conditions. These calculations typically require conguration of inputs including differential pressure, static pressure, process temperature, and for AGA-7, a turbine meter input.

The integral multi-variable transmitter (MVT) is used to measure static pressure and differential pressure. A 4-wire, 100-ohm platinum RTD is recommended for measuring process temperature. Where temperature is relatively constant, a xed temperature value may be congured.

Orice Plate (DP Input). The Scanner 2000 calculates natural gas ow rate from orice plates using calculation methods found in the AGA-3 or ISO-5167 measurement standards. The natural gas uid properties, such as density and compressibility, are calculated in accordance with AGA-8 (Detail and Gross methods). Heating values are calculated in accordance with AGA Report 3, Part 3, Appendix F using the gas properties dened in GPA 2145. Molar mass (molecular weight) calculations are also based on GPA 2145.

NuFlo Cone Meter (DP Input). The Scanner 2000 calculates natural gas ow rate from cone meters using industry-recognized algorithms identied in the NuFlo Cone Meter User Manual. The natural gas uid properties, such as density and compressibility, are calculated in accordance with AGA-8 (Detail and Gross methods). Heating values are calculated in accordance with AGA Report 3, Part 3, Appendix F using the gas properties dened in GPA 2145. Molar mass (molecular weight) calculations are also based on GPA 2145.

Gas Turbine Meter (Frequency Input). The Scanner 2000 calculates natural gas ow rate from a gas turbine meter using calculations found in the AGA-7 measurement standard. The natural gas uid properties, such as density and compressibility, are calculated in accordance with AGA-8 (Detail and Gross methods). Heating values are calculated in accordance with AGA Report 3, Part 3, Appendix F using the gas properties dened in GPA 2145. Molar mass (molecular weight) calculations are also based on GPA 2145.

Averaging Pitot Tube Meter (Annubar

averaging pitot tube meter using calculations found in the ASME MFC-12M-2006 measurement standard. The natural gas uid properties, such as density and compressibility, are calculated in accordance with AGA-8 (Detail and Gross methods). Heating values are calculated in accordance with AGA Report 3, Part 3, Appendix F using the gas properties dened in GPA 2145. Molar mass (molecular weight) calculations are also based on GPA 2145.

Therefore, an RTD is not required. The optional Chisholm and James wet correction methods are supported for the measurement of vapor and uid.

Page 9

Scanner® 2000 microEFM Section 1

NuFlo Cone Meter (DP Input). The Scanner 2000 supports steam measurement using industry-recognized algorithms identied in the NuFlo Cone Meter User Manual. Fluid properties for steam are calculated in accordance with the IAPWS Industrial-Formulation 1997 (IF-97) standard. Temperature is calculated according to IF-97 for saturated steam, based on static pressure. Therefore, an RTD is not required. The optional Steven wet correction method is supported for the measurement of vapor and uid.

Averaging Pitot Tube Meter (Annubar

). The Scanner 2000 supports steam measurement based on ASME MFC-12M -2006 ow rate methods for averaging pitot tube meters. Fluid properties are calculated in accordance with the IAPWS Industrial-Formulation 1997 (IF-97) standard. Temperature is calculated according to IF-97 for saturated steam, based on static pressure. Therefore, an RTD is not required. Wet correction methods are not supported.

Compensated Liquid

The Scanner 2000 measures compensated petroleum liquid ow using an orice, cone, liquid turbine, or averaging pitot tube (Annubar for use with any of these owmeters.

• The “generic” uid properties calculation method is used to measure liquids such as water or emulsions,

based on user-supplied viscosity values and either user-supplied density values or user-supplied liquid

Measurement Canada Seal Kit

Scanner 2000 devices approved by Measurement Canada for custody transfer applications must be installed

according to Measurement Canada regulations. Those regulations require the installation of a jumper and a device seal to prevent changes to the conguration of a device after the unit has been congured and the seal has been applied. An optional seal kit (Part No. 2295583-01) supplied by Cameron contains a jumper, a lead seal assembly, an Allen wrench and a label for properly marking a device. See Measurement Canada Seal Kit,

page A-14, for kit installation instructions.

When installed with a Scanner 2000, the assembly is rated for Class I, Div. 1, Groups C and D and Class I, Div. 2, Groups A, B, C, and D. If the Scanner is supplied without the terminal housing, it is approved for installation in Group B areas as well as Group C and D areas. See Terminal Housing, page A-16, for a diagram of a typical installation.

Foundation™ Fieldbus Communications

Foundation™ eldbus communications are now available for the Scanner 2000 and must be specied at the time of order. Each eldbus unit is designed with an expansion board that allows Modbus signals from the Scanner 2000 to be converted to eldbus prior to the distribution of eldbus data to devices on a eldbus network. See Appendix C—Scanner 2000 for Foundation™ Fieldbus for installation details.

Fieldbus communications are also available in an ATEX-approved intrinsically safe Scanner 2000. See

Power Options

The standard Scanner 2000 microEFM can be powered two ways:

• with the internal lithium battery pack supplied with each Scanner 2000 (shown in Figure 1.5)

• with an external customer-supplied power supply (6 to 30 VDC); the lithium battery provides backup

power when an external power supply is used

Wiring diagrams are provided in Section 3—Wiring the Scanner 2000.

Foundation™ eldbus models are powered by a customer-supplied eldbus power supply. In the event that

Interface Software Functions

The ModWorX™ Pro interface software is designed for simplicity and ease of use. Its intuitive, wellorganized screens allow users to calibrate and congure the Scanner 2000 microEFM within just a few minutes, and download log archives in an easy-to-read report. RTU Modbus® protocol and RS-485 communications ensure easy access to logs. Up to 16 user-selectable parameters can be logged and downloaded using ModWorX™ Pro software.

The software interface is designed around the most common needs of the eld operator. A read-only Main screen (Figure 1.6) provides a quick reference to real-time totals and ow rates, input data, and system data. It is also home to four task-based menus: Calibrate, Maintain Flow Run, Maintain Turbine, or Congure, and a large red “Download” button for downloading archive data.

Page 22

Section 1 Scanner® 2000 microEFM

Figure 1.6—ModWorX™ Pro software interface

The standard Scanner 2000 microEFM saves up to 2304 interval logs (interval periods are adjustable from 5 sec to 12 hours ), 768 daily logs, and 1152 event/alarm logs in nonvolatile memory. With the optional expansion board, the Scanner 2000 saves up to 6392 interval logs. A user can selectively download data logs and instrument conguration settings using the ModWorX™ Pro software. The download les are stored in an uneditable format on the user’s CPU, and can be viewed immediately or exported to an alternative format (.csv, .xls, .rtf, html, Flow-Cal®, or PGAS®).

Log data can be viewed or printed as a table or a trend chart, or exported to a spreadsheet.

Event logs track user changes to ow parameters that impact log data. Such changes may include orice plate changes, K-factor changes, input setting changes, and device events like over-range and resets. Event/alarm logs can be viewed or printed in tabular format. In addition to showing old and new values, each event log is time-stamped, and includes the register associated with the change.

Instructions for installing the software are provided on the installation CD pocket folder provided with each

instrument. User manuals containing step-by-step instructions on software functions are linked to the software interface for quick and easy access (note the tabbed links at the bottom of the screen in Figure 1.6).

LCD/Keypad Functions

From the three-button keypad on the front of the instrument, the user can perform the following tasks:

• scroll through display parameters

• view daily ow totals

• save a current total

• check the temperature and system voltage

• congure basic parameters such as slave address, baud rate, time, turbine K-factor, and orice plate size

Wiring Precautions

CAUTION In accordance with EN60079-0, Clause 16.5, all cable and cable glands must be rated for

80ºC. The Scanner 2000 may be tted as a remote unit when all the cable entries are tted with ameproof glands that have been suitably certied by a notied body.

CAUTION When a stand off tube is used to connect a turbine meter to an ATEX-approved Scanner

2000, it shall be used only with the turbine meter pick off coil bosses listed in certicate 03ATEX1474U.

RTD Assembly Options (for Gas and Liquid Flow Runs Only)

The process temperature input is typically supplied by an RTD installed in a thermowell downstream of the

primary differential pressure source. The location of the thermowell should conform to the relative standard to ensure accurate measurement. Use only an RTD assembly that is tted with a suitably certied, EX d IIC, cable entry gland, such as the ameproof RTD listed in Table 6.2, page 84 (Part No. 9A-X-TTXR-0003).

Class I, Div. 1 (CSA) Installations

The Scanner 2000 is CSA-certied as explosion-proof for Class I, Division 1, Groups B, C and D hazardous locations when sold individually. The Scanner is certied for Class I, Division 1, Groups C and D when sold with a Model TH4 terminal housing.

Wiring Precautions

CAUTION All signal cable from other devices and power must be installed in accordance with lo-

cal wiring practices for area classication. The cable used between the Scanner 2000

and other devices must be either armored MC-HL type cable or standard cable routed through conduit. If standard cable is used, a conduit seal must be installed within 18 inches of the Scanner.

When the Scanner 2000 is sold with a Model TH4 terminal housing, no conduit seal is required between the two devices.

RTD Assembly Options (for Gas and Liquid Flow Runs Only)

The process temperature input is typically supplied by an RTD installed in a thermowell downstream of the

primary differential pressure source. The location of the thermowell should conform to the relative standard to ensure accurate measurement. A 2-wire, 3-wire, or 4-wire RTD assembly may be used.

Cameron’s Barton Model 21 RTD, a 4-wire, 100-ohm explosion-proof RTD assembly, can be connected to the Scanner 2000 enclosure without conduit or a conduit seal. For details, see Explosion-Proof RTD Assembly

(CSA, Class I, Div. 1), page A-3.

RTDs that do not carry the explosion-proof rating can be used if they are routed through conduit and a conduit

seal is installed within 18 inches of the Scanner 2000.

Page 29

Scanner® 2000 microEFM Section 2

Class I, Div. 2 (CSA) Installations

The Scanner 2000 is certied for Class I, Division 2, Groups B, C and D hazardous locations.

Wiring Precautions

CAUTION All eld wiring must conform to the National Electrical Code, NFPA 70, Article 501-4(b)

for installations within the United States or the Canadian Electric Code for installations

within Canada. Local wiring ordinances may also apply. All eld wiring must be rated for

temperatures of 90°C or higher, and have a wire range of 22 to 14 AWG. Terminal block screws must be tightened to a minimum torque of 5 to 7 in-lbs. to secure the wiring

within the terminal block. Only personnel who are experienced with eld wiring should

perform these procedures.

RTD Assembly Options (for Gas and Liquid Flow Runs Only)

The process temperature input is typically supplied by an RTD installed in a thermowell downstream of the

primary differential pressure source. The location of the thermowell should conform to the relative standard to ensure accurate measurement. A 2-wire, 3-wire, or 4-wire RTD assembly may be used. A weatherproof RTD tted with a weatherproof Type 4 strain relief is recommended for Div. 2 installations.

Pressure Safety Precautions

WARNING: Before connecting the Scanner 2000 microEFM to a ow line, consider the

pressure rating of the sensor, and the presence of harmful gases. The tubing and xtures used to connect the sensor to the manifold in the ow line must be manufactured from materials that

are appropriate for the pressure ratings of the sensor used. If H2S is present, use a NACE sensor and take appropriate precautions to avoid exposure to this hazardous gas.

Mounting Options

The Scanner 2000 microEFM can be mounted using the following methods:

• Direct-mount to an orice or cone type DP meter. The integral multi-variable sensor may be connected to the pressure taps with stabilizers or a heavy wall nipple with adapter anges, and a 5-valve manifold (Figure 2.1, page 31). A bottom-port MVT is recommended for gas measurement; a side-mount MVT is recommended for liquid or steam measurement.

• Direct-mount to a turbine meter. The CSA-certied instrument can be mounted to a turbine meter using a pipe adapter and union connection (Figure 2.2, page 31). The ATEX-certied instrument can be mounted to a Barton 7000 Series meter using a turbine meter pickup extension (Figure 2.3, page 32).

• Pole-mount. The instrument can be mounted on a 2-in. pole using a NuFlo hardware kit, or bulkheadmounted to a at, vertical surface (Figure 2.4, page 32). Pole mounting may be preferred where limited space or pipe vibration prohibits direct-mount installation. A horizontal pipe mount is recommended for liquid and steam installations using a side-port MVT and block manifold. Tubing is used to connect the integral MVT to the orice meter or cone meter. If a Scanner 2000 will be used for steam measurement, a condensate pot must also be installed to protect the Scanner 2000 from extreme temperatures. See Mea-

suring Steam via a Differential Pressure Meter, page 42, for details.

The following accessories are also recommended:

• a 5-valve manifold for connecting process lines to the integral MVT

• an RTD assembly for process temperature input on gas ow runs and compensated liquid ow runs (not recommended for steam ow runs). See Hazardous Area Installations, page 27, for a description of RTD options to meet specic hazardous area requirements.

• tubing and/or pipe for plumbing process connections

• explosion-proof signal cable for remote turbine connections (stranded, shielded cable is recommended)

• terminal housing for expanding the number of inputs/outputs that can be connected to the Scanner 2000

Pole-Mount Installation

To mount the Scanner 2000 using the optional pole-mount kit, perform the following steps:

1. Determine the pipe orientation (horizontal or vertical) that will best accommodate process connections and eld wiring connections. A horizontal pipe mount is recommended for liquid and steam installations using a side-port MVT and block manifold.

2. Connect the mounting bracket to the Scanner 2000 using the two bolts provided (Figure 2.4, page 32).

3. Position the U-bolt around the pipe and through the support bracket provided with the U-bolt.

4. Align the mounting bracket against the pole so that the U-bolt passes through the mounting holes in the bracket. Place the mounting plate over the threaded ends of the U-bolt and against the bracket, and secure the U-bolt with the two nuts provided.

5. Install and connect process piping between the Scanner 2000 and the turbine meter with appropriate ttings. Process piping installation procedures vary with each application.

Measuring Natural Gas via a Differential Pressure Meter

Note This section contains installation guidelines for orice and cone meters. If installing the Scanner 2000

with an averaging pitot tube meter, refer to manufacturer instructions for installation.

Best Practices for Orice and Cone Meter Installation

To ensure measurement accuracy, ensure that the meter run complies with the following AGA-3 and ISO 5167 guidelines, as applicable:

• Do not place unit near vents or bleed holes that discharge corrosive vapors or gases.

• Consider the orientation of the meter run when determining the best position for mounting the Scanner

2000.

– If the Scanner 2000 is mounted to a horizontal pipeline, make sure process connections are at the top

of the line, and mount the Scanner 2000 above the pressure connections at the pipe.

– If the Scanner 2000 is mounted to a vertical pipeline, install the sensor above the differential pressure

source connections, or install a condensate (drip) pot to prevent the accumulation of liquid in interconnecting tubes. Slope all tubing upward at least 1-inch/linear foot to avoid liquid entrapment.

• Mount the Scanner 2000 as near level as possible such that the operator has a clear view of the LCD, and

can access the keypad easily when the enclosure cover is removed. The location should be as free from vibration as possible.

• Make sure the high port of the sensor (marked “H”) is connected to the upstream side of the meter run.

• Flow should remain subsonic throughout the measuring section and should be single phase.

• Pipe diameters (D) should be between 2 in. (50 mm) and 39 in. (1000 mm) per ISO 5167; or greater than

2 in. (50 mm) per AGA-3.

• Pipe Reynolds numbers must be above 5000.

• d (orice diameter) must be greater than or equal to 0.45 in. (11.5 mm).

• β (diameter ratio) must be greater than or equal to 0.1 and less than or equal to 0.75.

• Gauge lines should be of uniform internal diameter and constructed of material compatible with the uid

being measured. For most applications, the bore should be no smaller than ¼ in. (6 mm) and preferably, 3/8 in. (10 mm) in diameter. The internal diameter should not exceed 1 in. (25 mm). If high-temperature uids are likely to be encountered, make sure the measuring tube used is rated for the anticipated temperature range.

• Gauge line length should be minimized to help prevent pulsation-induced errors.

• Gauge lines should slope downward to the meter at a minimum of one inch per foot.

• If gauge lines must slope in more than one direction, do not allow more than one bend and install a liquid

or gas trap, as applicable. A liquid trap should be installed at the lowest point in a gas service installation.

• Gauge lines should be supported to prevent sag and vibration.

• Where pulsation is anticipated, full-port manifold valves with a nominal internal diameter consistent with

the gauge lines are recommended.

Page 34

Section 2 Scanner® 2000 microEFM

If the Scanner 2000 is mounted to a cone meter, consider the following best practices in addition to the best

practices listed above.

• Position the cone meter so that there are zero to ve pipe diameters upstream of the meter and zero to three pipe diameters downstream of the meter.

• Install the meter so that the static pressure tap is upstream of the differential pressure tap. The high side of the integral Scanner 2000 sensor must also be situated upstream.

• Install shut-off valves directly on the DP meter pressure taps. Choose a shut-off valve that is rated for the

ambient temperatures of the location and the operating pressure of the pipe in which it will be installed,

and for use with dangerous or corrosive uids or gases, if applicable. The valves must not affect the transmission of the differential pressure signal.

Installation Procedure—Direct Mount to Orice Meter or Cone Meter

A Scanner 2000 can be mounted directly to an orice meter or cone meter for gas measurement. The setup of the meter run and plumbing congurations can vary widely, depending upon the challenges existing on location. Figure 2.5 shows a typical direct-mount installation.

WARNING HAZARDOUS AREA USE. The Scanner 2000 is certied for hazardous area use only when

installed in accordance with applicable standards and local wiring practices. Carefully review Hazardous Area Installations, page 27, to determine specic installation requirements (cable glands, conduit seals, signal cable, RTD, etc.).

1. Verify that the meter is properly installed in the ow line (per manufacturer’s instructions).

2. Bolt a ange-by-ange 5-valve manifold (as recommended by Cameron) to the Scanner 2000 MVT sen-

sor.

a. Locate the H and L markings on the integral MVT sensor body and position the MVT/manifold as-

sembly so that the upstream side of the ow line can easily be connected to the sensor’s “High” port and the downstream side of the ow line can be connected to the sensor’s “Low” port. The Scanner 2000 enclosure can be rotated to face the desired direction.

b. Position the manifold so that all valves are accessible from the front of the instrument.

3. Connect the Scanner 2000 and manifold assembly to the differential pressure meter. Hardware require-

ments will vary, depending upon the installation conguration. However, minimally, an adapter is required that can span between the threaded pressure tap/orice ange connector and the non-threaded manifold. This adapter can be a one-piece stabilizer (often preferred for added strength and stability) or a short heavy wall pipe nipple attached to a futbol ange (available from Cameron). Use a suitable compound or tape on all threaded process connections.

CAUTION Do not use Teon® tape on the threads of the union, adapter, or pipe plugs. Use of

Teon® tape will void the explosion-proof rating of the instrument.

4. Install the RTD assembly in the thermowell. Route the RTD assembly cable through the conduit opening

in the top of the Scanner 2000 to connect to the main circuit board. A wiring diagram for the RTD assem-

bly is provided in Figure 3.5, page 66. For hazardous areas, review Hazardous Area Installations, page 27.

5. Route any additional inputs/outputs or COM connections, etc. through the conduit opening in the top of

the Scanner 2000. For hazardous areas, review Hazardous Area Installations, page 27.

6. Perform a manifold leak test as described on page 55.

7. Verify the zero offset, if required (and other calibration points, if desired). See the ModWorX™ Pro Soft-

ware User Manual, Part No. 9A-30165025, for complete instructions. See also Zero Offset (Static Pres-

sure or Differential Pressure), page 56, Static Pressure Calibration and Verication, page 56, and Differential Pressure Calibration and Verication, page 57.

CAUTION Do not put the Scanner into operation until the valves are positioned properly so that

pressure is supplied to both sides of the MVT. For instructions on proper valve positions, see Placing the Scanner into Operation, page 58.

Installation Procedure—Remote Mount to Orice Meter or Cone Meter

A Scanner 2000 can be mounted remotely and connected to an orice meter or cone meter with tubing for gas measurement. The setup of the meter run and plumbing congurations can vary widely, depending upon the challenges existing on location. Figure 2.6 shows a typical remote-mount installation.

Measuring Natural Gas via a Turbine Meter

Best Practices

The Scanner 2000 microEFM calculates gas ow through a turbine meter in accordance with AGA-7 and API 21.1 industry standards. For optimum performance, ensure that the turbine and Scanner 2000 installation complies with the industry recommendations listed below:

• Install the turbine owmeter in the meter run such that there are 10 nominal pipe diameters upstream and ve nominal pipe diameters downstream of the meter. Both inlet and outlet pipe should be of the same nominal size as the meter.

• Straightening vanes are recommended for eliminating swirl conditions. If used, they should be installed ve pipe diameters upstream of the meter.

• Where an RTD is used to facilitate compensated gas measurement from a gas turbine meter, locate the RTD within ve pipe diameters downstream of the meter outlet and upstream of any valve or ow restriction.

Installation Procedure—Remote Mount to a Turbine Meter

A Scanner 2000 can be mounted remotely and connected to a gas turbine meter for measuring gas in

accordance with AGA-7 calculations. Figure 2.7, page 39, shows an installation in which the pressure input is provided by the integral MVT. Alternatively, if an optional expansion board is installed in the Scanner 2000, an external explosion-proof pressure transducer can be used to supply the pressure. See Installation

Procedure—Direct Mount to a Turbine Meter (CSA Compliant), page 40, for more information.

The setup of the meter run and plumbing congurations can vary widely, depending upon the challenges existing on location.

WARNING HAZARDOUS AREA USE. The Scanner 2000 is certied for hazardous area use only when

To connect the Scanner 2000 to a turbine meter, perform the following steps:

1. Verify that the owmeter and magnetic pickup are installed in the ow line.

2. Mount the Scanner 2000 to a 2-in. pipe or to a at, vertical surface using bolts and the mounting holes in the enclosure.

3. Bolt a 3-valve ange-by-NPT manifold (as recommended by Cameron) to the Scanner 2000 MVT sensor. Position the manifold so that all valves are accessible from the front of the instrument.

4. Connect the pressure port of the turbine meter to either manifold process port with tubing. The unused pressure port can be used as a “vent” as required. Always leave the equalizer valves open to allow pressure to both sides of the MVT. Use a suitable compound or tape on all threaded process connections.

Measuring Steam via a Differential Pressure Meter

Note This section contains installation guidelines for orice and cone meters. If installing the Scanner 2000

with an averaging pitot tube meter, refer to manufacturer instructions for installation.

Best Practices

The Scanner 2000 calculates steam ow in accordance with IF-97, AGA-3, and ISO-5167 industry standards. For optimum performance, ensure that the installation complies with the following industry recommendations:

Condensate pots

• A condensate pot for a small-volume transducer like the Scanner 2000 MVT can be a simple pipe tee, oriented so that one port extends downward (into the cold leg), the opposite port extends upward and is closed by a pipe cap or blowdown valve, and the tee extends horizontally into the hot leg.

• The pots should be the highest point in the system.

• The pots should be mounted at the same level, and one or both should be adjustable vertically to remove zero shifts in the differential pressure measurement.

Hot legs

• Hot legs should be large diameter (3/8 in. or 1/2 in., if possible)

• Hot legs should be as short as possible. If these sections must be more than 1 ft. in length, insulate them.

• Elbows and bends should not form any traps in which liquid can accumulate.

• Hot legs should be sloped along their entire length to allow liquids to drain back into the pipe.

Cold legs

• Cold legs should enter the multi-variable sensor through its side ports.

• Cold legs should be a minimum of 2 ft in length to allow proper convection cooling and should be run horizontally with a slope of approximately 1 inch per foot to allow air bubbles to oat up into the pots.

• Elbows and bends should not form any traps for air bubbles.

• Cold legs should be lled with a suitable antifreeze. Dibutyl phthalate is recommended.

Antifreeze

• Dibutyl phthalate (DBP) has the following advantages over glycol antifreeze:

– DBP doesn’t mix with water, and so doesn’t become dilute over time; its specic gravity doesn’t shift.

– It is slightly denser than water, so it will stay in the pot permanently.

– It is non-ammable.

– It is much less toxic than glycol.

– It is available from industrial suppliers.

Valves

• Use only full-opening block valves that are rated for steam service.

• Use only blowdown valves that are rated for steam service. Periodic blowdowns are recommended for preventing buildup of scale.

Page 43

Scanner® 2000 microEFM Section 2

CAUTION Before starting the system, remove the caps and add water or antifreeze if necessary to

completely ll the pots and cold legs. Air trapped in the lines will produce errors in differential pressure measurements.

Installation Procedure—Remote Mount to Orice Meter or Cone Meter

A Scanner 2000 can be mounted remotely and connected to an orice meter or cone meter with tubing for steam measurement. The setup of the meter run and plumbing congurations can vary widely, depending upon the challenges existing on location.

WARNING HAZARDOUS AREA USE. The Scanner 2000 is certied for hazardous area use only when

Condensate pot (pipe tee with blowdown valve attached)

Long cold legs protect the sensor from extreme process temperatures

3/4 in. conduit connection for input/output & communications

Cold legs connect to manifold (slope to eliminate air trap)

MVT vent (use for for filling cold legs)

Hot legs, insulated to within 1 ft of condensate pot (1/2 in. diameter recommended)

Horizontal pole mount provides clearance for block manifold

Figure 2.9—Remote-mount steam run installation (shown here with a cone meter). The remote-mount method

can be used with an orice meter as well.

Page 44

Section 2 Scanner® 2000 microEFM

CAUTION When measuring steam, process connections must be designed to eliminate air pock-

ets. This is achieved by making sure all tubing in the cold legs slopes upward. A sideport MVT and block manifold (shown in Figure 2.9) is recommended to help prevent air bubbles from being trapped in the sensor.

If a bottom-port MVT is used, the bottom process ports must be plugged or replaced with a drain valve, and side vents must be used for process connections. A block manifold is

not recommended for use with bottom port MVTs. Contact a Cameron eld representative

for assistance.

1. Verify that the meter is properly installed in the ow line (per manufacturer’s instructions).

2. Mount the Scanner 2000 to a 2-in. pipe or to a at, vertical surface using bolts and the mounting holes in the enclosure. A horizontal pipe is recommended, as additional hardware may be required for a vertical pipe mount to provide clearance for the manifold block.

3. Mount a set of pipe tees (which serve as condensate pots) typically on either side of the Scanner 2000 at an elevation above the process connections of the Scanner 2000 MVT (for proper drainage). They should be a considerable distance (4 ft) from the sensor ports, but as close as possible to the pressure taps on the meter.

4. Install a pipe cap or a blowdown valve that is rated for steam service at the top of each pipe tee. A blowdown valve is recommended when the steam passing through the meter is known to be dirty.

5. Install tubing and ttings to connect the high-pressure and low-pressure taps of the DP meter to the pipe tees. This section is typically referred to as the hot legs of the installation, as this section of tubing encounters steam at its highest temperature. Install a shut-off valve near the high and low ports of the DP meter. Use a suitable compound or tape on all threaded process connections.

6. Route any additional inputs/outputs or COM connections, etc. through the conduit opening in the top of the Scanner 2000. For hazardous areas, review Hazardous Area Installations, page 27.

Note: To prevent ttings from turning and/or to avoid putting tension on stainless steel tubing, use a backup

wrench to attach stainless steel tubing to shut-off valves, or sensor ports.

CAUTION Whenever possible, locate the hot legs of a steam installation behind the Scanner 2000

safely out of the operator’s normal reach. This will help prevent accidental burns.

7. Install tubing to connect the high-pressure and low-pressure process connections of the block manifold to the pipe tees installed in step 3. This tubing section is typically referred to as the cold legs of the installa- tion, since it is lled with water.

8. To eliminate air bubbles, ll the cold legs with water or other ll uid from the lowest point in the system, typically the MVT, using the following steps:

a. Open the blowdown valve or remove the lling plug from one of the pipe tees/condensate pots.

b. Open the equalizer and bypass/block valves on the block manifold. Make sure the vent valve is

closed.

c. Remove the corresponding (high pressure or low pressure) vent screw from the side of the MVT and

insert a tting to allow connection of a hand pump or funnel. If a funnel is used, attach a length of Tygon tubing that is long enough to elevate the funnel well above the condensate pot to force the uid up the legs.

Page 45

Scanner® 2000 microEFM Section 2

d. Connect a hand pump or funnel to the tting.

e. Pour ll liquid into the funnel or pump it into the cold leg, tapping the cold leg occasionally to dis-

lodge any bubbles.

f. Observe the pipe tee/condensate pot and stop pouring when the ll liquid is visible at the top and no

air bubbles can be seen.

g. Remove the tting from the vent of the MVT and quickly replace the vent screw and tighten.

h. Close the blowdown valve or replace the lling plug from one of the pipe tees/condensate pots.

i. Repeat steps a through h for the other cold leg.

9. To eliminate an offset of the differential pressure reading, open the equalizer valves on the block manifold,

remove the caps from the seal pots, and adjust either seal pot vertically to bring the water levels to the exact

same elevation.

10. Perform a manifold leak test as described on page 55.

11. Verify the zero offset, if required (and other calibration points, if desired). See the ModWorX™ Pro Soft-

ware User Manual, Part No. 9A-30165025, for complete instructions. See also Zero Offset (Static Pressure

or Differential Pressure), page 56, Static Pressure Calibration and Verication, page 56, and Differential Pres- sure Calibration and Verication, page 57.

CAUTION Do not put the Scanner into operation until the valves are positioned properly so that

pressure is supplied to both sides of the MVT. For instructions on proper valve positions, see Placing the Scanner into Operation, page 58.

Measuring Liquid via a Differential Pressure Meter

Note This section contains installation guidelines for orice and cone meters. If installing the Scanner 2000

with an averaging pitot tube meter, refer to manufacturer instructions for installation.

Best Practices

To ensure measurement accuracy, ensure that the meter run complies with the following AGA-3 and ISO 5167 guidelines, as applicable:

• Do not place unit near vents or bleed holes that discharge corrosive vapors or gases.

• Consider the orientation of the meter run when determining the best position for mounting the Scanner.

– If the Scanner 2000 is mounted to a horizontal pipeline, make sure process connections are horizon-

tal with the pipeline, or sloped downwards towards the Scanner. Mount the Scanner 2000 below the pressure taps at the pipe. Use the side (upper) ports as process connections and the bottom ports for draining and lling the DP housings.

– If the Scanner 2000 is mounted to a vertical pipeline, install the sensor below the differential pressure

source connections. Slope all tubing downward at least 1-inch/linear foot to avoid gas entrapment.

• Mount the Scanner 2000 as near level as possible such that the operator has a clear view of the LCD, and can access the keypad easily when the enclosure cover is removed. The location should be as free from vibration as possible.

• Make sure the high port of the sensor (marked “H”) is connected to the upstream side of the meter run.

• Pipe diameters (D) should be between 2 in. (50 mm) and 39 in. (1000 mm) per ISO 5167; or greater than 2 in. (50 mm) per AGA-3.

• Pipe Reynolds numbers must be above 5000. Avoid high-viscosity liquids (greater than 15 cP).

• d (orice diameter) must be greater than or equal to 0.45 in. (11.5 mm).

• Orice β (diameter ratio) must be greater than or equal to 0.1 and less than or equal to 0.75.

• Gauge lines should be of uniform internal diameter and constructed of material compatible with the uid being measured. For most applications, the bore should be no smaller than ¼ in. (6 mm) and preferably, 3/8 in. (10 mm) in diameter. The internal diameter should not exceed 1 in. (25 mm). If high-temperature uids are likely to be encountered, make sure the measuring tube used is rated for the anticipated temperature range.

• If there is possibility of freezing, the gauge lines can be lled with a suitable seal liquid. The seal liquid should be somewhat denser than the process uid, should not dissolve in it, should have a sufciently low freezing point, and should be non-toxic. Alternatively, heat tracing can be used.

• Gauge line length should be minimized to help prevent pulsation-induced errors.

• Gauge lines should slope upward to the meter at a minimum of one inch per foot.

• If gauge lines must slope in more than one direction, do not allow more than one bend and install a gas trap.

• Gauge lines should be supported to prevent sag and vibration.

• Where pulsation is anticipated, full-port manifold valves with a nominal internal diameter consistent with the gauge lines are recommended.

If the Scanner 2000 is mounted to a cone meter, consider the following guidelines in addition to the best

Page 47

Scanner® 2000 microEFM Section 2

practices listed above.

• Position the cone meter so that there are zero to ve pipe diameters upstream of the meter and zero to

three pipe diameters downstream of the meter.

• Install the meter so that the static pressure tap is upstream of the differential pressure tap. The high side of

the integral Scanner 2000 sensor must also be situated upstream.

• Install shut-off valves directly on the DP meter pressure taps. Choose a shut-off valve that is rated for the

ambient temperatures of the location and the operating pressure of the pipe in which it will be installed,

and for use with dangerous or corrosive uids or gases, if applicable. The valves must not affect the transmission of the differential pressure signal.

Installation Procedure—Direct Mount to Orice Meter or Cone Meter

A Scanner 2000 can be mounted directly to an orice meter or cone meter for liquid measurement using a side-port MVT, a block manifold and two football ange adapters (Figure 2.10). The setup of the meter run and plumbing congurations can vary widely, depending upon the challenges existing on location.

MVT with side ports

Figure 2.10—Direct-mount liquid run installation (shown here with a cone meter). Downstream RTD is not shown.

CAUTION When measuring liquid with a direct-mount Scanner 2000, process connections must be

parallel to the horizontal centerline of the meter, or below the centerline to eliminate air pockets.

Block manifold

Adapter (2 typ.)

1. Verify that the meter is properly installed in the ow line (per manufacturer’s instructions).

2. Screw a football ange adapter onto each meter pressure tap using pipe tape or pipe dope to seal the

threads.

Page 48

Section 2 Scanner® 2000 microEFM

3. Align the bolt holes in the Scanner 2000 MVT and manifold, and install bolts to mate these components to the football anges, using o-rings as appropriate. Torque the bolts to the manufacturer’s specication.

4. Route any additional inputs/outputs or COM connections, etc. through the conduit opening in the top of the Scanner 2000. For hazardous areas, review Hazardous Area Installations, page 27.

5. Verify that all manifold valves are closed, and ll the meter with process uid.

6. Loosen one of the vent screws in the side of the MVT.

7. Open the equalizer valves and the vent valve on the manifold.

8. Slowly open one of the bypass/block valves on the manifold. Process uid should immediately spurt from the MVT vent.

9. When air bubbles are no longer visible around the MVT vent, tighten the MVT vent screw.

10. Loosen the other vent screw in the side of the MVT, and repeat steps 7 through 9.

11. Perform a manifold leak test as described on page 55.

12. Verify the zero offset, if required (and other calibration points, if desired). See the ModWorX™ Pro Software User Manual, Part No. 9A-30165025, for complete instructions. See also Zero Offset (Static Pressure

or Differential Pressure), page 56, Static Pressure Calibration and Verication, page 56, and Differential Pres- sure Calibration and Verication, page 57.

CAUTION Do not put the Scanner into operation until the valves are positioned properly so that

pressure is supplied to both sides of the MVT. For instructions on proper valve positions, see Placing the Scanner into Operation, page 58.

Installation Procedure—Remote Mount to Orice Meter or Cone Meter

A Scanner 2000 can be mounted remotely and connected to an orice meter or cone meter with tubing for liquid measurement (Figure 2.11). The setup of the meter run and plumbing congurations can vary widely, depending upon the challenges existing on location.

WARNING HAZARDOUS AREA USE. The Scanner 2000 is certied for hazardous area use only when

CAUTION When measuring liquid, process connections must be designed to eliminate air pockets.

This is achieved by mounting the sensor below the metering device and sloping all tubing downward from the meter to the sensor. A side-port MVT and block manifold (shown in Figure 2.11) is recommended to help prevent air bubbles from being trapped in the sensor.

If a bottom-port MVT is used, the bottom process ports must be plugged or replaced with a drain valve, and side vents must be used for process connections. A block manifold is

not recommended for use with bottom port MVTs. Contact a Cameron eld representative

for assistance.

Shut-off valves throttle flow to the manifold and MVT

Positioning of sensor below the meter and slope of tubing helps prevent gas bubbles from entering the liquid

Figure 2.11—Remote-mount liquid run installation (shown here with a cone meter). The remote-mount method

can be used with an orice meter as well.

1. Verify that the meter is properly installed in the ow line (per manufacturer’s instructions).

2. Mount the Scanner 2000 to a 2-in. pipe or to a at, vertical surface using bolts and the mounting holes in

the enclosure. A horizontal pipe is recommended, as additional hardware may be required for a vertical pipe mount to provide clearance for the manifold block.

3. Install tubing and ttings to connect the high-pressure and low-pressure taps of the DP meter to the pro-

cess connections of the block manifold. Install a pair of shut-off valves near the high and low ports of the DP meter. Use a suitable compound or tape on all threaded process connections.

4. Install the RTD assembly in the thermowell. Remove the plug from a conduit opening in the top of the

Scanner 2000 enclosure, route the RTD assembly cable through the conduit opening and connect it to the main circuit board. A wiring diagram for the RTD assembly is provided in Figure 3.5, page 66. For hazard- ous areas, review Hazardous Area Installations, page 27.

5. Route any additional inputs/outputs or COM connections, etc. through the conduit opening in the top of

the Scanner 2000. For hazardous areas, review Hazardous Area Installations, page 27.

Note To prevent ttings from turning and/or to avoid putting tension on stainless steel tubing, use a backup

wrench to attach stainless steel tubing to shut-off valves, or sensor ports.

6. To eliminate air bubbles in the MVT, manifold, and legs connecting them to the meter, ll the legs with

uid. Choose a uid that is safe for the environment, and stable when depressurized.

Page 50

Section 2 Scanner® 2000 microEFM

Important If the process uid does not present an environmental risk and is stable when depressur-

ized, it may be used to bleed air from the lines. If the process uid can contaminate the environment, or is highly volatile when depressurized as with liquied gases, a different seal uid should be used to ll the legs. An ideal seal uid is one that does not dissolve

in the process uid.

Bleeding with Process Fluid

g. Make sure the shut-off valves in the tubing near the meter pressure taps are closed, and the meter is

lled with process uid.

h. Open the equalizer and bypass/block valves on the block manifold. Make sure the vent valve is

closed.

i. Open one of the shut-off valves near the meter.

j. Slowly loosen the corresponding vent screw on the MVT, and throttle the rate of ow from the vent

with the shut-off valve.

k. When air bubbles are no longer visible around the MVT vent, tighten the MVT vent screw.

l. Repeat steps a through e for the other leg.

Bleeding with a Different Seal Fluid

m. Make sure the shut-off valves in the tubing near the pressure taps are open.

n. Open the equalizer and bypass/block valves on the block manifold. Make sure the vent valve is

closed.

o. Remove the vent screw from one side of the MVT and insert a tting to allow connection of a hand

pump or funnel. If a funnel is used, attach a length of Tygon tubing that is long enough to elevate the funnel well above the meter pressure taps to force the uid up the legs.

p. Connect a hand pump or funnel to the tting.

q. Estimate the amount of ll uid required to ll the tubing and push any air bubbles into the meter.

r. Pour ll liquid into the funnel, tapping the tubing occasionally to dislodge any bubbles.

s. When the leg is full of uid, remove the tting from the vent of the MVT and quickly replace the vent

screw and tighten.

t. Repeat steps a through g for the other leg.

6. Perform a manifold leak test as described on page 55.

7. Verify the zero offset, if required (and other calibration points, if desired). See the ModWorX™ Pro Software User Manual, Part No. 9A-30165025, for complete instructions. See also Zero Offset (Static Pressure

or Differential Pressure), page 56, Static Pressure Calibration and Verication, page 56, and Differential Pres- sure Calibration and Verication, page 57.

CAUTION Do not put the Scanner into operation until the valves are positioned properly so that

pressure is supplied to both sides of the MVT. For instructions on proper valve positions, see Placing the Scanner into Operation, page 58.

Measuring Compensated Liquid via a Turbine Meter

Best Practices

The Scanner 2000 microEFM calculates compensated liquid ow through a turbine meter in accordance with API-2540 and the measurement principles upon which the AGA-7 standard is based. The user supplies a

linear or multi-point calibration factor, and the instrument performs the required compensation calculations,

based on the RTD input.

For optimum performance, ensure that the turbine and Scanner 2000 installation complies with the industry

recommendations listed below:

• Install the turbine owmeter in the meter run such that there are at least 10 nominal pipe diameters up-

stream and ve nominal pipe diameters downstream of the meter. Both inlet and outlet pipe should be of the same nominal size as the meter.

• Straightening vanes are recommended for eliminating swirl conditions. If used, they should be installed

ve pipe diameters upstream of the meter.

Installation Procedure—Direct Mount to a Turbine Meter (CSA Compliant)

A Scanner 2000 without the MVT bottomworks can be mounted directly to a liquid turbine meter for

measuring liquid (Figure 2.12). A pipe adapter and union are attached to the Scanner, allowing a direct connection to the turbine meter.

Performing a Manifold Leak Test

A manifold leak test is recommended prior to operating any differential pressure meter into service. Check the manifold for leaks as follows.

1. Verify that the instrument is approximately level

and is properly connected to the pressure source.

EQUALIZER

2. Make sure the vent valve in the manifold is closed.

(The bypass/block valves should be open.)

3. Close both bypass/block valves on the manifold to

isolate pressure between the block valve and the

MVT.

4. Open both equalizer valves to distribute pressure throughout.

BYPASS/ BLOCK

EQUALIZER

VENT

BYPASS/ BLOCK

Page 56

Section 2 Scanner® 2000 microEFM

5. Monitor the pressure readout and watch for a steady decrease in pressure. If leakage is indicated, depressurize the system by opening both bypass/block valves, then check all manifold and piping joints. Tighten connections as necessary.

6. Repeat steps 3 through 5 to retest the manifold for leaks.

An additional test can verify the condition of the equalizing valves. Assuming the above test has conrmed the system is leak free, close both equalizing valves and open the vent. Monitor the differential pressure reading for any change. Repair or replace the manifold as required if the differential pressure varies.

Zero Offset (Static Pressure or Differential Pressure)

The static pressure input for the Scanner 2000 is zeroed at the factory before shipment. However, changes

in temperature and atmospheric pressure can cause the

static pressure and differential pressure readings to vary. The inputs can be easily zeroed in the eld, if necessary, prior to putting the Scanner 2000 into service.

EQUALIZER

To zero the static pressure or differential pressure

VENT

1. Close the bypass valves to isolate the pressure below the manifold.

BYPASS/ BLOCK

2. Open the equalizer and vent valves.

3. Connect to the Scanner 2000 with the ModWorX™ Pro software, and apply zero pressure from the Cali- brate Inputs screen (see the ModWorX™ Pro Software User Manual; Part No. 9A-30165025; for complete instructions).

Static Pressure Calibration and Verication

Note The pressure range stamped on the MVT is expressed as psia (absolute). However, Scanner 2000

pressure inputs are recalibrated as psig (gauge) at the factory before the device is shipped. Therefore, pressure readings displayed on the LCD and in the ModWorX Pro software are in terms of psig.

The static pressure and differential pressure inputs are calibrated and veried before the Scanner 2000 leaves the factory, and recalibration in the eld may or may not be required. To comply with API standards for verication, “as found” readings should be recorded at approximately 0, 50, and 100 percent of the operating pressure range, increasing, and at 80, 20 and 0 percent of the operating pressure range, decreasing. For example, the static pressure measurements of a 1500-psi sensor should be veried at 0 psi, 750 psi, and 1500 psi, then at 1200 psi, 300 psi, and 0 psi.

WARNING: Do not subject the Scanner 2000 microEFM to unnecessary shock or over-range

pressure during maintenance operations.

To calibrate the static pressure

1. Close the bypass valves to isolate the pressure below the manifold.

2. Open the equalizer valves and vent valve to purge the lines.

3. Close the vent valve.

4. Connect a static pressure simulator to the manifold (either side).

Section 3—Wiring the Scanner 2000

Field Wiring Connections

WARNING: Do not connect/disconnect equipment or change batteries unless the area is known

to be non-hazardous. The Scanner 2000 poses no hazard when opened in a safe area.

CAUTION All eld wiring must conform to the National Electrical Code, NFPA 70, Article 501-4(b)

for installations within the United States or the Canadian Electric Code for installations

within Canada. Local wiring ordinances may also apply. All eld wiring must be rated for

temperatures of 90°C or higher, and have a wire range of 22 to 14 AWG. Terminal block screws must be tightened to a minimum torque of 5 to 7 in-lbs. to secure the wiring

within the terminal block. Only personnel who are experienced with eld wiring should

perform these procedures.

To wire the Scanner 2000 for operation, complete the following eld connections:

1. Unscrew the cover of the enclosure counter-clockwise until it separates from the main body of the enclo-

sure.

2. Using a small standard blade screwdriver, remove the two #4-40 × 7/8” screws located to the right and

left side of the display.

3. Lift the display/keypad assembly from the enclosure, making sure the circuit assembly does not contact

the enclosure.

4. Connect the lithium battery to the J1 connector on the circuit assembly. See Figure 3.2, page 63.

5. Connect wiring for external power, if appropriate. See Grounding Procedures, page 62, and see Figure 3.3,

page 64 for a wiring diagram.

6. Connect the owmeter input wiring to terminal block TB2, if appropriate. See Figure 3.4, page 65.

7. Connect the process temperature input wiring to terminal block TB2, if appropriate. See Figure 3.5, page

66.

8. Connect wiring for output signals, if appropriate. See Figure 3.6, page 67, Figure 3.7, page 68, and Figure

3.8, page 69. If the instrument is equipped with an expansion board, connect wiring for expansion board

inputs/outputs, if appropriate. See page A-10 for expansion board wiring diagrams.

9. Place the circuit assembly over the standoffs and fasten with the two #4-40 × 7/8” screws, ensuring that

all connector wiring is inside the enclosure and in no position where it may be damaged when the enclo-

sure cover is replaced.

10. Recalibrate the Scanner 2000 (if necessary).

11. If external and internal power supplies were removed, reset the clock to ensure that the time stamps in the

log data are accurate. The clock can be reset using the instrument keypad or ModWorX™ Pro software.

12. Replace the enclosure cover by threading it onto the enclosure in a clockwise direction.

Section 3 Scanner® 2000 microEFM

Grounding Procedures

To power the Scanner 2000 microEFM with an external DC supply, route the ground conductor through a conduit opening in the top of the Scanner 2000 enclosure with the power conductors and connect it to the

ground screw inside the enclosure (note the round sticker that marks this location in Figure 3.1).

If national or local electrical codes require the enclosure to be grounded, a protective earth grounding

conductor may be required. To install a protective earth ground, connect an earth ground conductor to the stainless ground lug near the top of the Scanner 2000 enclosure (also shown in Figure 3.1) or to the internal ground screw, and connect the other end to a ground rod or other suitable system earth ground. The ground lugs will accept wire sizes from 14 AWG solid conductor to 4 AWG stranded conductor.

Power Supply Wiring

Internal Power Supply

The Scanner 2000 microEFM is shipped with a lithium battery pack. To supply power to the instrument, connect the battery cable to connector J1 on the main circuit assembly (Figure 3.2).

Low-power microprocessor technology enables the Scanner 2000 to operate for an estimated 1 year on a lithium battery pack. The lithium battery pack is ideal for use in extreme temperatures, although extreme cold temperatures may reduce battery life.

To maximize battery life,

• operate the Scanner using the following default conguration settings:

– calculation frequency: 1 minute

– logging frequency (interval): 1 hour

– download frequency: monthly

• disconnect the Scanner 2000 from the RS-232 to RS-485 converter when ModWorX Pro software is not

in use. When ModWorX Pro is running, the computer powers the converter; when the software is not running, the Scanner 2000 powers the converter, causing a current drain to the Scanner battery.

• avoid the following conditions/activities:

– operation at extremely cold temperatures

– use of digital output (pulse or alarm)

– use of analog input without external power (when expansion board is installed)

Section 3 Scanner® 2000 microEFM

When an external power supply is used as the primary power source, the lithium battery pack serves as

a backup power supply. The use of an alternate power source extends battery life and helps ensure that timekeeping and volume accumulation will not be interrupted during a power failure.

External Power Supply

The Scanner 2000 can be connected to a remote power supply by a two-conductor cable (Figure 3.3). The power supply and cable must be capable of supplying 6 to 30 VDC @ 50 mA.

The external power supply must be an approved SELV source, insulated from the AC main by double/ reinforced insulation per CSA C22.2 No.61010-1-04 / UL 61010-1 – 2nd Edition.

Important In all applications using an external power supply, a switch or circuit breaker must be in-

cluded in the safe area external power supply installation within easy reach of the operator. The switch or circuit breaker must be marked as the “disconnect” for the safe area external DC power supply.

Important If the main circuit board is marked with a revision level of 02 or older (revisions 01, C, B,

or A), a zener diode (Part No. 1.5KE33CA) must be installed for CE approval. The zener

diode is not required for revision 03 and newer circuit boards.

Output Wiring

Digital Output (Pulse or Alarm)

The standard Scanner 2000 supports a solid-state digital output that is congurable as either a pulse output or an alarm output. As a pulse output, the pulse width duration and pulse representation are both congurable. Because the circuit is isolated, it can be used in conjunction with any other feature on the Scanner 2000. A two-conductor cable from the Scanner 2000 to the remote location is required. The maximum rating of the digital output circuit is 60 mA at 30 VDC. Maximum frequency is 50 Hz. Wire as shown in Figure 3.6.

For reduced power consumption, turn the digital output feature off when it is not in use.

Important If the main circuit board is marked with a revision level of 02 or older (revision 01, C, B,

or A), a zener diode (Part No. IN4752) must be installed for CE approval. The zener diode is not required for revision 03 and newer circuit boards.

Conguration via Keypad

Communication parameters such as slave address and baud rate, the date and time, contract hour and plate

size can all be congured via the three-button keypad on the front of the instrument. See Section 4—

Conguration and Operation via Keypad for step-by-step instructions. All other instrument calibration is

performed via the ModWorX™ Pro software.

WARNING: To prevent ignition of hazardous atmospheres, do not remove the cover while cir-

cuits are alive. The Scanner 2000 poses no hazard when opened in a safe area.

Conguration via ModWorX™ Pro Software

A laptop connection and the ModWorX™ Pro software provided with the Scanner 2000 are required for

the calibration and conguration of the instrument. The Scanner 2000’s natural gas and steam calculations typically require conguration of inputs including differential pressure, static pressure, process temperature, and for AGA-7, a turbine meter input.

The Scanner 2000 microEFM supports digital serial communications using EIA-RS-485 hardware with Modicon Modbus® protocol. Either of two Modbus® slave ports facilitates communications with a laptop or PC. The baud rate range for both ports is 300 to 38.4K. Both ports are protected from high-voltage transients.

IMPORTANT: The Scanner 2000 for Foundation™ eldbus has a single port for communications.

An RS-232 to RS-485 converter or NuFlo USB adapter is required for connecting the microEFM to a laptop or PC. The converters available from Cameron require no handshaking or external power to operate. See

Section 6—Spare Parts for ordering information; see Figure 3.7, page 68, and Figure 3.8, page 69, for wiring

instructions.

The NuFlo USB adapter provides an external USB port for connecting to a laptop, and is available as a kit for upgrading a Scanner 2000. See USB Communications Adapter (CSA Div. 1 or Div. 2), page A-6 for details;

see Section 6—Spare Parts for ordering information.

WARNING: To prevent ignition of hazardous atmospheres, do not remove the Scanner 2000

cover while circuits are alive. The Scanner 2000 poses no hazard when opened in a safe area.

Scanner® 2000 microEFM Section 5

Section 5—Scanner 2000 Maintenance

The Scanner 2000 is engineered to provide years of dependable service with minimal maintenance. Batteries

require periodic replacement, and battery life depends on whether battery power is the primary or secondary

power source, the conguration settings of the Scanner 2000, and ambient temperature conditions.

All conguration settings are stored in nonvolatile memory; therefore, conguration settings will not be lost in the event of battery failure.

The circuit assembly or keypad may also require replacement over the life of the instrument. Replacement procedures are provided in this section.

WARNING: Before servicing the Scanner 2000, disconnect all power sources/signal sources or

verify that the atmosphere is free of hazardous gases.

Lithium Battery Pack Replacement

The Scanner 2000 uses a lithium battery pack with a typical life expectancy of 1 year. Due to the at discharge characteristics of the lithium battery, it is difcult to determine how much life remains in a battery at any given time. To preserve conguration and accumulated volume data, replace the battery pack at 1-year intervals.

WARNING: To prevent ignition of hazardous atmospheres, do not remove the cover while cir-

cuits are alive. The Scanner 2000 poses no hazard when opened in a safe area.

WARNING: The lithium battery pack that powers the Scanner 2000 is a sealed unit; however,

should a lithium battery develop a leak, toxic fumes could escape upon opening the enclosure. Ensure that the instrument is in a well-ventilated area before opening the enclosure to avoid breathing fumes trapped inside the enclosure. Exercise caution in handling and disposing of spent or damaged battery packs. See additional information in Appendix B—Lithium Battery

Information, page B-1.

Important Press the ENTER/SAVE key on the keypad before replacing the lithium battery pack to

save accumulated grand totals and previous day totals for ow run and turbine volume,

energy, and mass to nonvolatile memory. Once the battery pack is replaced and power is restored to the unit, the last saved accumulated totals will be displayed in the LCD. The

instrument clock will need to be reset following battery replacement. All conguration

and calibration settings are automatically saved to non-volatile memory and are not affected by a temporary loss of battery power.

The lithium battery pack is secured inside the enclosure by a velcro strap and connected to a connector (J1) near the top of the circuit assembly.

To replace a lithium battery pack in the Scanner 2000, perform the following steps:

1. Unscrew the cover of the enclosure counter-clockwise until it separates from the main body of the enclo-

sure.

2. Using a small standard blade screwdriver, remove the two #4-40 × 7/8” screws located to the right and

left side of the display (Figure 5.1, page 78).

Page 78

Section 5 Scanner® 2000 microEFM

3. Lift the display/keypad assembly from the enclosure, making sure the circuit assembly does not contact the enclosure.

4. Loosen the velcro strap, disconnect the battery from the J1 connector on the circuit assembly, and remove the spent battery pack from the enclosure (Figure 5.1).

Remove screws to release keypad/circuit board assembly from enclosure

Figure 5.1—Removal of the battery pack from the enclosure

5. Install the new battery pack in the enclosure in the same position as the original battery pack, and secure the Velcro tightly around it.

6. Connect the replacement battery pack to the J1 connector.

7. Place the circuit assembly over the standoffs and fasten with the two #4-40 × 7/8” screws, ensuring that all connector wiring is inside the enclosure.

8. Replace the enclosure cover, threading it onto the enclosure in a clockwise direction.

Important An interruption of power to the Scanner 2000 will cause the internal clock time to be

incorrect. Reset the time using the keypad on the switchplate or the ModWorX™ Pro software. See Editing the Date and Time, page 74, for details.

Circuit Assembly Replacement

WARNING: To prevent ignition of hazardous atmospheres, do not remove the cover while cir-

cuits are alive. The Scanner 2000 poses no hazard when opened in a safe area.

• 1 analog output (4-20 mA)

A-8

Page 95

Scanner® 2000 microEFM Appendix A

If the expansion board is ordered with a Scanner 2000, it is installed at the factory. If the board is purchased separately, the user will need to install it on the Scanner 2000 main board using the following instructions.

Installation (for boards purchased separately from a Scanner 2000)

Important Before installing the expansion board, remove all power from the Scanner 2000

(battery and external power). Remove wiring from the main board if necessary to guide the expansion board into position.

The expansion board attaches to two headers positioned between the two large green terminal blocks on the

main board. To install, perform the following steps:

1. Remove the standoff from packaging and push it into the hole near the middle of the main board until it

snaps into place.

2. Guide the expansion board over the standoff and align the pins on the under side of the expansion board

with the headers on the main board. FAILURE TO ALIGN PINS AND HEADERS CAN RESULT IN DAMAGE TO THE BOARD. When the board is positioned correctly, the text on both boards should face the same direction.

3. Gently press the expansion board and the main board together until the expansion board snaps into place

over the standoff.

4. Restore eld wiring connections to the main board, if applicable, and install eld wiring on the expansion

board.

Wiring Diagrams

Analog Inputs 1 and 2

The analog inputs, which can be congured for a 0-5 V, 1-5 V or 4-20 mA signal, can be used to receive readings from a pressure or temperature transmitter for use in AGA-7 gas calculations. Alternatively, they can be used to log measurements from any device with a 0-5 V, 1-5 V or 4-20 mA output.

Transmitter power is provided by the Scanner 2000 only when the Scanner is externally powered. The output voltage equals the input voltage less 0.25 VDC, and is limited to 20 mA.

If a 4-20 mA transmitter is used, a resistor must be added to the circuit, as shown in Figure A.15. The expansion board circuit will support a resistor range of 200 to 300 ohms; 250 ohms is recommended.

Pulse Input

The pulse input provides an optically isolated input for high-amplitude pulse (frequency) signals, which includes signals from a turbine meter equipped with a preamplier (Figure A.16, top diagram) or signals from a positive displacement meter (Figure A.16, bottom diagram).

The Scanner 2000 can calculate ow from no more than two pulse (frequency) inputs at a time. Therefore, a pulse input can be used simultaneously with only one turbine input (main board or expansion board).

The pulse input can also be used as a status input for monitoring a parameter via Modbus

registers. See Pulse

Input for Status Indication, page D-25, for details.

Analog (4-20 mA) Output

The 4-20 mA output provides a linear current output that can be congured using ModWorX Pro software to represent any parameter in the holding registers. This output requires a two-conductor cable to be connected to an 8 to 30 VDC power supply (voltage required is dependent on loop resistance) and a current readout device to be located in the remote location. See the ModWorX Pro Software User Manual for information on conguring zero and full-scale values using ModWorX Pro software.

The graph below the wiring diagram in Figure A.18, page A-13 shows the minimum voltage required to power the instrument for a given loop resistance. In addition, the mathematical relationship between loop voltage and load resistance is given. For example, if a power supply voltage of 24 volts is available to power the current loop, the maximum load resistance would be 800 ohms.
