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.

Section 1 Scanner® 2000 microEFM

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

Steam

The Scanner 2000’s saturated steam calculations compensate for the effects of pressure, temperature, steam

properties, and steam quality.

Orice Plate (DP Input). The Scanner 2000 supports steam measurement based on AGA-3 or ISO-5167 ow rate methods for orice plates. Fluid properties are calculated in accordance with the IAPWS IndustrialFormulation 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 Chisholm and James wet correction methods are supported for the measurement of vapor and uid.

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.

Terminal Housing/Junction Box

Cameron’s Model TH4 terminal housing expands the number of devices or I/O connections that can be added to a Scanner 2000. The terminal housing is approved by CSA for use with the Scanner 2000. 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

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.

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

In that mode, the user can congure the following parameters without the use of a laptop computer:

• slave address

• baud rate

• date and time

• contract hour

• orice plate size

Step-by-step instructions are provided in Section 4—Conguration and Operation via Keypad. All other

instrument conguration is performed via the ModWorX™ Pro software interface.

Viewing Daily and Hourly Logs

Up to 99 consecutive daily logs can be viewed using the keypad.

Pressing the Log button changes the LCD display mode from normal operation (scrolling) to a daily log view mode (Figure 1.10). The two-digit ashing number or “log index” on the left side of the LCD represents the number of days that have passed since the log was saved. The user can increment or decrement the number by clicking the UP ARROW or DOWN ARROW buttons. For example, “01” will display the last daily log saved. An index of “05” will display the daily log saved 5 days ago.

By default, the top display shows ow volume, however the user can congure the display to show any of the 16 parameters available using ModWorX™ Pro software. The bottom display shows the date. The entire

Section 2—Installing the Scanner 2000

Overview

The Scanner 2000 microEFM is fully assembled at the time of shipment and ready for mounting. However, Cameron recommends that operators congure the microEFM prior to mounting if the instrument is to be installed in a hazardous area. The enclosure must be opened to congure the device, either via keypad controls

or via software, and once the instrument is mounted in a hazardous area, the cover should not be removed

unless the area is void of combustible gas and vapors.

Hazardous Area Installations

The Scanner 2000 is ATEX-certied (Zone 1) and CSA-certied (Div. 1 and Div. 2) for hazardous area use. Installation requirements vary, depending on the certication required. Carefully review the following hazardous area requirements before installing a Scanner 2000 in a hazardous area.

Section 2 Scanner® 2000 microEFM

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.

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.
