Reference Manual Introduction

00809-0100-8782 November 2019

2 Introduction

2.1 System description

The flowmeter consists of a sensor and a transmitter. The sensor is installed in-line with the process piping; the transmitter is remotely mounted away from the sensor.

Figure 2-1: 8782 transmitter

Figure 2-2: MS sensor

The flow sensor contains two magnetic coils located on opposite sides of the sensor. Two electrodes, located perpendicular to the coils and opposite each other, make contact with the liquid. The transmitter energizes the coils and creates a magnetic field. A conductive liquid moving through the magnetic field generates an induced voltage at the electrodes. This voltage is proportional to the flow velocity. The transmitter converts the voltage detected by the electrodes into a flow reading. A cross-sectional view is show in Figure 2-3.

Remote Transmitter Installation

3.1 Handling and Lifting Safety

CAUTION

To reduce the risk of personal injury or damage to equipment, follow all lifting and handling instructions.

• Handle all parts carefully to prevent damage. Whenever possible, transport the

system to the installation site in the original shipping container.

• PTFE-lined sensors are shipped with end covers that protect flange sealing surfaces

from both mechanical damage and normal unrestrained distortion. Remove the end covers just before installation.

• Keep the shipping plugs in the conduit ports until you are ready to connect and seal

them. Appropriate care should be taken to prevent water ingress.

• The sensor should be supported by the pipeline. Pipe supports are recommended on

both the inlet and outlet sides of the sensor pipeline. There should be no additional support attached to the sensor.

• Use proper PPE (Personal Protection Equipment) including safety glasses and safety

shoes.

• Do not lift the meter by holding the electronics housing or junction box.

• The sensor liner is vulnerable to handling damage. Never place anything through the

sensor for the purpose of lifting or gaining leverage. Liner damage can render the sensor useless.

• Do not drop the device from any height.

3.1.1 Lifting lugs

CAUTION

If provided, use the lifting lugs on each flange to handle the flow meter when it is transported and lowered into place at the installation site. If lifting lugs are not provided, the flow meter must be supported with a lifting sling on each side of the housing.

• Standard pressure 3 inch through 36 inch flanged magnetic flowmeters come with

lifting lugs.

• High pressure (above 600#) 3 inch through 24 inch flanged magnetic flow meters

come with lifting lugs.

A. Without lifting lugs

B. With lifting lugs

3.2 Location and Position

3.2.1 Environmental considerations

To ensure maximum transmitter life, avoid extreme temperatures and excessive vibration. Typical problem areas include the following:

• Tropical/desert installations in direct sunlight

• Outdoor installations in arctic climates

3.2.2

Upstream and downstream piping

To ensure specified accuracy over widely varying process conditions, it is recommended to install the sensor with a minimum of five straight pipe diameters upstream and two pipe diameters downstream from the electrode plane.

3.2.3

A. Five pipe diameters (upstream)

B. Two pipe diameters (downstream)

C. Flow direction

Installations with reduced upstream and downstream straight runs are possible. In reduced straight run installations, the meter may not meet accuracy specifications. Reported flow rates will still be highly repeatable.

Flow direction

The sensor should be mounted so that the arrow points in the direction of flow.

Figure 3-3: Flow direction arrow

3.2.4

Reference Manual 15

Sensor piping location and orientation

The sensor should be installed in a location that ensures it remains full during operation. Depending on where it is installed, orientation must also be considered.

• Vertical installation with upward process fluid flow keeps the cross-sectional area full,

regardless of flow rate.

• Horizontal installation should be restricted to low piping sections that are normally full.

Electrode orientation

The electrodes in the sensor are properly oriented when the two measurement electrodes are in the 3 and 9 o’clock positions or within 45 degrees from the horizontal, as shown on the left side of Figure 3-5. Avoid any mounting orientation that positions the top of the sensor at 90 degrees from the vertical position as shown on the right of Figure 3-5.

The sensor may require a specific orientation to comply with Hazardous Area T-code rating. Refer to the appropriate reference manual for any potential restrictions.

3.3 Sensor Installation

3.3.1 Flanged sensors

Gaskets

The sensor requires a gasket at each process connection. The gasket material must be compatible with the process fluid and operating conditions. Gaskets are required on each side of a grounding ring (see Figure 3-6). All other applications (including sensors with lining protectors or a grounding electrode) require only one gasket on each process connection.

Note

Metallic or spiral-wound gaskets should not be used as they will damage the liner face of the sensor. If spiral wound or metallic gaskets are required for the application, lining protectors must be used.

Sensor Installation Reference Manual

November 2019 00809-0100-8782

Bolts

Note

Do not bolt one side at a time. Tighten both sides simultaneously. Example:

1. Snug upstream

2. Snug downstream

3. Tighten upstream

4. Tighten downstream

Do not snug and tighten the upstream side and then snug and tighten the downstream side. Failure to alternate between the upstream and downstream flanges when tightening bolts may result in liner damage.

Suggested torque values by sensor line size and liner type are listed in Table 3-2 for ASME B16.5 flanges and Table 3-3 or Table 3-4 for EN flanges. Consult the factory if the flange rating of the sensor is not listed. Tighten flange bolts on the upstream side of the sensor in the incremental sequence shown in Figure 3-7 to 20% of the suggested torque values. Repeat the process on the downstream side of the sensor. For sensors with greater or fewer flange bolts, tighten the bolts in a similar crosswise sequence. Repeat this entire tightening sequence at 40%, 60%, 80%, and 100% of the suggested torque values.

If leakage occurs at the suggested torque values, the bolts can be tightened in additional 10% increments until the joint stops leaking, or until the measured torque value reaches the maximum torque value of the bolts. Practical consideration for the integrity of the liner often leads to distinct torque values to stop leakage due to the unique combinations of flanges, bolts, gaskets, and sensor liner material.

Check for leaks at the flanges after tightening the bolts. Failure to use the correct tightening methods can result in severe damage. While under pressure, sensor materials may deform over time and require a second tightening 24 hours after the initial installation.

Figure 3-7: Flange bolt torquing sequence

Prior to installation, identify the lining material of the flow sensor to ensure the suggested torque values are applied.

3.4 Process reference connection

The figures shown in this section illustrate best practice installations for process reference connections only. For installations in conductive, unlined pipe it may be acceptable to use one ground ring or one lining protector to establish a process reference connection. Earth safety ground is also required as part of this installation, but is not shown in the figures. Follow national, local, and plant electrical codes for safety ground.

Use Table 3-5 to determine which process reference option to follow for proper installation.

This chapter provides instructions for installing and wiring a remotely mounted transmitter.

Related information

Sensor Installation

4.1 Pre-installation

Before installing the transmitter, there are several pre-installation steps that should be completed to make the installation process easier:

• Identify options and configurations that apply to your application

• Set the hardware switches if necessary

• Consider mechanical, electrical, and environmental requirements

Note

Refer to Product Specifications for more detailed requirements.

Identify options and configurations

The typical transmitter installation includes a device power connection, a 4-20mA output connection, and sensor coil and electrode connections. Other applications may require one or more of the following configurations or options:

• Pulse output

• Discrete input/discrete output

• HART multidrop configuration

The transmitter may have up to four user-selectable hardware switches. These switches set the alarm mode, internal/external analog power, internal/external pulse power, and transmitter security. The standard configuration for these switches when shipped from the factory is as follows:

Table 4-1: Hardware switch default settings

Setting Factory configuration

Alarm mode High

Internal/external analog power Internal

Internal/external pulse power External

Transmitter security Off

The analog power switch and pulse power switches are not available when ordered with intrinsically safe output, ordering code B.

In most cases, it is not necessary to change the setting of the hardware switches. If the switch settings need to be changed, refer to Hardware switches.

Reference Manual 25

Remote Transmitter Installation Reference Manual

November 2019 00809-0100-8782

Be sure to identify any additional options and configurations that apply to the installation. Keep a list of these options for consideration during the installation and configuration procedures.

Mechanical considerations

The mounting site for the transmitter should provide enough room for secure mounting, easy access to conduit entries, full opening of the transmitter covers, and easy readability of the Local Operator Interface (LOI) screen (if equipped).

4.3.2 Surface mounting

Attach the transmitter to the mounting location using customer supplied mounting screws. The installation of the transmitter shall be rated for four (4) times the weight of the transmitter or 44lbs (20kgs).

4.4 Wiring

4.4.1 Conduit entries and connections

Transmitter conduit entries ports are ½"-14NPT as standard, M20 conduit connections will use an adapter. Conduit connections should be made in accordance with national, local, and plant electrical codes. Unused conduit entries should be sealed with the appropriate certified plugs. The plastic shipping plugs do not provide ingress protection.

4.4.2

Conduit requirements

• For installations with an intrinsically safe electrode circuit, a separate conduit for the

coil cable and the electrode cable may be required. Refer to Product

Certifications.Refer to the product reference manual.

• For installations with non-intrinsically safe electrode circuit, a single dedicated conduit

run for the coil drive and electrode cable between the sensor and the remote transmitter may be acceptable. Removal of the barriers for intrinsic safety isolation is permitted for non-intrinsically safe electrode installations.

• Bundled cables from other equipment in a single conduit are likely to create

interference and noise in the system. See Figure 4-3.

• Electrode cables should not be run together in the same cable tray with power cables.

• Output cables should not be run together with power cables.

• Select conduit size appropriate to feed cables through to the flowmeter.

Cable preparation

Prepare the ends of the coil drive and electrode cables as shown in Figure 4-5. Remove only enough insulation so that the exposed conductor fits completely under the terminal connection. Best practice is to limit the unshielded length (D) of each conductor to less than one inch. Excessive removal of insulation may result in an unwanted electrical short to the transmitter housing or other terminal connections. Excessive unshielded length, or failure to connect cable shields properly, may also expose the unit to electrical noise, resulting in an unstable meter reading.

Reference Manual Basic Configuration

00809-0100-8782 November 2019

5 Basic Configuration

Once the flow meter is installed and power has been supplied, the transmitter must be configured using the LOI, if equipped, or a configuration tool, such as ProLink III Software. Descriptions of more advanced functions are included in Advanced Configuration

Functionality.

5.1 Basic Setup

Tag

Tag is the quickest and shortest way of identifying and distinguishing between transmitters. Transmitters can be tagged according to the requirements of your application. The transmitter supports the 8 character Tag and the 32 character Long Tag. Both parameters are available for configuration.

Calibration number

The sensor calibration number is a 16-digit number generated at the factory during flow calibration, is unique to each sensor, and is located on the sensor nameplate.

Flow units (PV)

The flow units variable specifies the format in which the flow rate will be displayed. Units should be selected to meet your particular metering needs. See Measurement units.

Line size

The line size (sensor size) must be set to match the actual sensor connected to the transmitter. The size must be specified in inches.

Upper range value (URV)

The URV sets the 20 mA point for the analog output. This value is typically set to full-scale flow. The units that appear will be the same as those selected under the flow units parameter. The URV may be set between –39.3 ft/s to 39.3 ft/s (–12 m/s to 12m/s). There must be at least 1 ft/s (0.3 m/s) span between the URV and LRV.

Note

If entering a negative number, the minus sign must be entered in the furthest left position on the LOI.

Lower range value (LRV)

The LRV sets the 4 mA point for the analog output. This value is typically set to zero flow. The units that appear will be the same as those selected under the flow units parameter. The LRV may be set between –39.3 ft/s to 39.3 ft/s (–12 m/s to 12m/s). There must be at least 1 ft/s (0.3 m/s) span between the URV and LRV.

Note

If entering a negative number, the minus sign must be entered in the furthest left position on the LOI.

Reference Manual 41

Basic Configuration Reference Manual

November 2019 00809-0100-8782

Auto zero

The Auto zero is recommended for optimum performance when a flow meter is initially installed, and it typically does not need to be performed again. However, if process conditions drastically change, a new Auto zero is recommended. The sensor must be filled completely with process fluid at zero flow. For more information, see Auto zero.

5.2 Local operator interface (LOI)

To access the transmitter menu, press the XMTR MENU key. Use the UP, DOWN, LEFT(E), and RIGHT arrows to navigate the menu structure.

A complete map of the LOI menu structure is shown in LOI Menu trees.

The display can be locked to prevent unintentional configuration changes. The display lock can be activated through a HART communication device, or by holding the UP arrow for three seconds and then following the on-screen instructions.

6.1 Hardware switches

The electronics are equipped with four user-selectable hardware switches. These switches set the Alarm Mode, Internal/External Analog Power, Transmitter Security, and Internal/ External Pulse Power.

Definitions of these switches and their functions are provided below. To change the settings, see below.

6.1.1 Alarm mode

If an event occurs that would trigger an alarm in the electronics, the analog output will be driven high or low, depending on the switch position. The switch is set in the HIGH position when shipped from the factory. Refer to Table 8-1 and Table 8-2 for analog output values of the alarm.

6.1.2

6.1.3

Transmitter security

The SECURITY switch allows the user to lock out any configuration changes attempted on the transmitter.

• When the security switch is in the ON position, the configuration can be viewed but no

changes can be made.

• When the security switch is in the OFF position, the configuration can be viewed and

changes can be made.

The switch is in the OFF position when the transmitter is shipped from the factory.

Note

The flow rate indication and totalizer functions remain active when the SECURITY switch is in either position.

Internal/external analog power

Note

With output option code B, the analog output can only be externally powered and there is no ANALOG switch.

The 4–20 mA loop can be powered internally by the transmitter or externally by an external power supply. The ANALOG switch determines the source of the 4–20 mA loop power.

• When the switch is in the INTERNAL position, the 4–20 mA loop is powered internally

by the transmitter.

• When the switch is in the EXTERNAL position, a 10-30 VDC external power supply is

required. For more information about 4–20 mA external power, see Analog output.

Reference Manual 45

Advanced installation details Reference Manual

November 2019 00809-0100-8782

The switch is in the INTERNAL position when the transmitter is shipped from the factory.

Note

External power is required for multidrop configurations.

6.1.4 Internal/external pulse power

Note

With output option code B, the pulse output can only be externally powered and there is no PULSE switch.

The pulse loop can be powered internally by the transmitter or externally or by an external power supply. The PULSE switch determines the source of the pulse loop power.

• When the switch is in the INTERNAL position, the pulse loop is powered internally by

the transmitter.

• When the switch is in the EXTERNAL position, a 5–28 VDC external supply is required.

For more information about pulse external power, see Connect pulse output.

The switch is in the EXTERNAL position when the transmitter is shipped from the factory.

6.1.5

Changing hardware switch settings

Note

The hardware switches are located on the top side of the electronics board and changing their settings requires opening the electronics housing. If possible, carry out these procedures away from the plant environment in order to protect the electronics.

November 2019 00809-0100-8782

• Discrete I/O Channel 2 can be configured as discrete output only (see Discrete input/

output).

6.2.1 Connect pulse output

The pulse output function provides a galvanically isolated frequency signal that is proportional to the flow through the sensor. The signal is typically used in conjunction with an external totalizer or control system.

Note

• With output option code A, the pulse output can be internally or externally powered,

and the PULSE switch must be set accordingly (the default setting is EXTERNAL).

• With output option code B, the pulse output can only be externally powered and there

is no PULSE switch. See Internal/external pulse power.

External power supply

For an externally powered pulse output, the following requirements apply:

• Supply voltage: 5 to 28 VDC

• Maximum current: 100 mA

• Maximum power: 1.0 W

• Load resistance: 200 to 10k Ohms (typical value 1k Ohms). Refer to the figure

6.3 Coil housing configuration

The coil housing provides physical protection of the coils and other internal components from contamination and physical damage that might occur in an industrial environment. The coil housing is an all-welded and gasket-free design.

The MS sensor model is available in four coil housing configurations. Configurations are identified by the M0, M1, M2, or M4 options codes found in the model number.

6.3.1 Standard coil housing configuration

The standard coil housing configuration is a factory sealed all-welded enclosure and is available for the following models (see Figure 6-12):

• MS with option code M0 - MSxxxxxxxxxxxxM0

Figure 6-12: Standard Housing Configuration

6.3.2

A. Conduit connection

B. No relief port (welded shut or absent)

Process leak protection (option M1)

The sensor is available with process leak detection through the use of a threaded connection and pressure relief valve (PRV). This coil housing configuration is a factory sealed all-welded enclosure.

• MS with option code M1 - MSxxxxxxxxxxxxM1

A PRV can be installed in the threaded connection to prevent possible over-pressuring of the coil housing caused by a primary seal failure. The PRV is capable of venting fugitive emissions when pressure inside the coil housing exceeds five psi. Additional piping may be connected to the PRV to drain any process leakage to a safe location (see Figure 6-13).

In the event of a primary seal failure, this configuration will not protect the coils or other internal components of the sensor from exposure to the process fluid.

Reference Manual Advanced installation details

00809-0100-8782 November 2019

Note

The PRV is supplied with the meter to be installed by the customer. Installation of the PRV and any associated piping must be performed in accordance with environmental and hazardous area requirements.

6.3.3

A. Conduit connection

B. M6 threaded pressure relief port with removable cap screw

C. Optional: Use relief port to plumb to safe area (supplied by user).

Process leak containment (Option M2 or M4)

The sensor is available with process leak containment. The coil housing configuration is a factory sealed all-welded enclosure with the addition of sealed electrode compartments.

• MS with option code M2/M4 - MSxxxxxxxxxxxxM2/M4

This configuration divides the coil housing into separate compartments, one for each electrode and one for the coils. In the event of a primary seal failure, the fluid is contained in the electrode compartment. The sealed electrode compartment prevents the process fluid from entering the coil compartment where it may damage the coils and other internal components. The electrode compartments are designed to contain the process fluid up to a maximum pressure of 740 psig.

• Code M2 - sealed, welded coil housing with separate sealed and welded electrode

compartments (see Figure 6-14).

• Code M4 - sealed, welded coil housing with separate sealed and welded electrode

compartments with a threaded port on the electrode tunnel cap, capable of venting fugitive emissions (see Figure 6-15).

Note

To properly vent process fluid from the electrode compartment to a safe location, additional piping is required and must be installed by the user. Installation of any associated piping must be performed in accordance with environmental and hazardous

6.3.4 Higher temperature applications and sensor insulation best practices

Insulation of the magnetic flowmeter sensor is not typically recommended. However, in applications with higher temperature process fluids (above 150°F / 65°C), plant safety, sensor reliability, and sensor longevity can be improved with careful attention to proper insulation.

1. In applications where process fluid permeation of the liner has been observed or may be expected, the rate of permeation can be reduced by decreasing the temperature gradient between the process fluid and the outside of the meter body. In these applications only the space between the process flanges and the coil housing should be insulated (see Figure 6-16).

Figure 6-16: Insulating a Rosemount Magnetic Flowmeter for Permeation

A. Process piping B. Coil housing C. Insulation

2. When insulation of the magnetic flowmeter sensor is required due to plant safety standards designed to protect personnel from contact burns, extend the insulation up to the coil housing, covering both ends of the sensor and flanges (Figure 6-17).

The insulation should NOT cover the coil housing or the terminal junction box. Insulating the coil housing and the terminal junction box can result in overheating of the coil compartment and terminals, resulting in erratic/erroneous flow readings and potential damage or failure of the meter.

8 Advanced Configuration

Functionality

8.1 Introduction

This section contains information for advanced configuration parameters.

The software configuration settings for the transmitter can be accessed through a HART®based communicator, Local Operator Interface (LOI), or through a control system. Before operating the transmitter in an actual installation, you should review all of the factory set configuration data to ensure that they reflect the current application.

8.2 Configure outputs

LOI menu path Detailed Setup → Output Config

8.2.1

The configure outputs functionality is used to configure advanced features that control the pulse, auxiliary, and totalizer outputs of the transmitter.

Analog output

LOI menu path Detailed Setup → Output Config → Analog

The analog output function is used to configure all of the features of the 4-20 mA output.

Upper range value

LOI menu path

The upper range value (URV) sets the 20 mA point for the analog output. This value is typically set to full-scale flow. The units that appear will be the same as those selected under the units parameter. The URV may be set between –39.3 ft/s to 39.3 ft/s (–12 m/s to 12 m/s) or the equivalent range based on the selected flow units. There must be at least 1 ft/s (0.3 m/s) span or equivalent between the URV and LRV.

Note

If entering a negative number, the minus sign must be entered in the furthest left position on the LOI.

Detailed Setup → Output Config → Analog → PV URV

Reference Manual 69

Advanced Configuration Functionality Reference Manual

November 2019 00809-0100-8782

Lower range value

LOI menu path Detailed Setup → Output Config, → Analog → PV LRV

The lower range value (LRV) sets the 4 mA point for the analog output. This value is typically set to zero flow. The units that appear will be the same as those selected under the units parameter. The LRV may be set between –39.3 ft/s to 39.3 ft/s (–12 m/s to 12 m/s) or the equivalent range based on the selected flow units. There must be at least 1 ft/s (0.3 m/s) span or equivalent between the URV and LRV.

Note

If entering a negative number, the minus sign must be entered in the furthest left position on the LOI.

Alarm type

LOI menu path

Detailed Setup → Output Config → Analog → Alarm Type

The analog output alarm type displays the position of the alarm switch on the electronics board. There are two available positions for this switch:

• High

• Low

Alarm level

Pulse output

LOI menu path Detailed Setup → Output Config → Pulse

Under this function the pulse output of the transmitter can be configured.

Pulse scaling

LOI menu path

Detailed Setup → Output Config → Pulse → Pulse Scaling

Transmitter may be commanded to supply a specified frequency between 1 pulse/ day at

39.37 ft/sec (12 m/s) to 10,000 Hz at 1 ft/sec (0.3 m/s).

Note

The maximum pulse scaling frequency for transmitters with an intrinsically safe output is 5000 Hz.

Reference Manual 71

Advanced Configuration Functionality Reference Manual

November 2019 00809-0100-8782

Note

Line size, special units, and density must be selected prior to configuration of the pulse scaling factor.

The pulse output scaling equates one transistor switch closure pulse to a selectable number of volume units. The volume unit used for scaling pulse output is taken from the numerator of the configured flow units. For example, if gal/min had been chosen when selecting the flow unit, the volume unit displayed would be gallons.

Note

The pulse output scaling is designed to operate between 0 and 10,000 Hz. The minimum conversion factor value is found by dividing the minimum span (in units of volume per second) by 10,000 Hz.

The best choice for this parameter depends upon the required resolution, the number of digits in the totalizer, the extent of range required, and the maximum frequency limit of the external counter.

Pulse factor units

LOI menu path Detailed Setup → Output Config → Pulse → Units

The pulse factor unit assigns the unit of measure to the pulse scaling factor. The default read-only value is the unit of measure from the configured flow units. For example, if gal/min is selected when configuring the flow units, the pulse factor unit will be gallons.

Pulse width

LOI menu path Detailed Setup → Output Config → Pulse → Pulse Width

The factory default pulse width is 0.5

ms.

The width, or duration, of the pulse can be adjusted to match the requirements of different counters or controllers (see

Figure 8-1). These are typically lower frequency

applications (< 1000Hz). The transmitter will accept values from 0.1 ms to 650 ms.

For frequencies higher than 1000Hz, it is recommended to set the pulse mode to 50% duty cycle by setting the pulse mode to frequency output.

The pulse width will limit the maximum frequency output, If the pulse width is set too wide (more than 1/2 the period of the pulse) the transmitter will limit the pulse output. See example below.

8.2.3 Totalizer

The totalizer provides the total amount of fluid that has passed through the meter. There are three available totalizers: Total A, Total B, and Total C. They can be independently configured for one of the following options:

• Net - increments with forward flow and decrements with reverse flow (reverse flow

must be enabled).

• Reverse total - will only increment with reverse flow if reverse flow is enabled

• Forward total - will only increment with forward flow

All totalizer values will be reset if line size is changed. This will happen even if the totalizer reset control is set to non-resettable.

The totalizers have the capability to increment the total to a maximum value of 50 feet per second of flow (or the volumetric equivalent) for a period of 20 years before roll-over occurs.

8.2.4 Discrete input/output

This configuration option is only available if the auxiliary output suite (option code AX) was ordered. The auxiliary output suite provides two channels for control.

• The discrete input can provide positive zero return (PZR) or reset totalizer (A, B, C, or all

totals).

Note

If a particular totalizer is configured to be not resettable, the totalizer will not be reset with this function.

• The discrete output control function can be configured to drive an external signal to

indicate zero flow, reverse flow, empty pipe, diagnostic status, flow limit, or transmitter status.

A complete list and description of the available auxiliary functions is provided below.

8.5 Additional parameters

The following parameters may be required for detailed configuration settings based on your application.

8.5.1

Reference Manual 85

Coil drive frequency

LOI menu path Detailed Setup → Additional Params → Coil Drive Freq

This parameter changes the drive frequency of the magnetic coils.

Advanced Configuration Functionality Reference Manual

November 2019 00809-0100-8782

Low

The standard coil drive frequency is Low. This is the recommended coil drive frequency setting for most applications.

High

If the process fluid causes a noisy or unstable flow reading, increase the coil drive frequency to High. If the coil drive frequency is set to High, the auto zero trim is highly recommended for optimal performance. Not performing the auto zero trim can lead to degraded accuracy, especially at low flow rates.

8.5.2 Process density

LOI menu path Detailed Setup → More Params → Proc Density

Use the process density value to convert from a volumetric flow rate to a mass flow rate using the following equation:

Qm = Qv x p

8.5.3

8.5.4

Where:

Qm is the mass flow rate

Qv is the volumetric flow rate, and

p is the fluid density

Reverse flow

LOI menu path Detailed Setup → Output Config → Reverse Flow

Use reverse flow to enable or disable the transmitter's ability to read flow in the opposite direction of the flow direction arrow (see Flow direction). This may occur when the process has bi-directional flow, or when either the electrode wires or the coil wires are reversed (see Troubleshooting Remote wiring). This also enables the totalizer to count in the reverse direction.

Low flow cutoff

LOI menu path Detailed Setup → Sig Processing → Lo-Flow Cutoff

Low flow cutoff allows the user to set a low flow limit to be specified. The low flow cutoff units are the same as the PV units and cannot be changed. The low flow cutoff value applies to both forward and reverse flows.

8.6.1

8.6.2

8.6.3

Base volume unit

LOI menu path Basic Setup → Flow Units → Special Units → Base Vol Units

Base volume unit is the unit from which the conversion is being made. Set this variable to the appropriate option.

Conversion factor

LOI menu path Basic Setup → Flow Units → Special Units → Conv Factor

The special units conversion factor is used to convert base units to special units. For a straight conversion of units from one unit of measure to a different unit of measure, the conversion factor is the number of base units in the new unit.

Example: If you are converting from gallons to barrels and there are 31 gallons in a barrel, the conversion factor is 31.

Base time unit

LOI menu path Basic Setup → Flow Units → Special Units → Base Time Unit

Base time unit provides the time unit from which to calculate the special units.For example, if your special units is a volume per minute, select minutes.

8.6.4

Reference Manual 87

Special volume unit

LOI menu path Basic Setup → Flow Units → Special Units → Volume Unit

Special volume unit enables you to display the volume unit format to which you have converted the base volume units.

Example: If the special units are abc/min, the special volume variable is abc. The volume units variable is also used in totalizing the special units flow.

Advanced Configuration Functionality Reference Manual

November 2019 00809-0100-8782

8.6.5 Special flow rate unit

LOI menu path Basic Setup → Flow Units → Special Units → Rate Unit

Flow rate unit is a format variable that provides a record of the units to which you are converting. The Handheld Communicator will display a special units designator as the units format for your primary variable. The actual special units setting you define will not appear. Four characters are available to store the new units designation. The LOI will display the four character designation as configured.

Example: To display flow in acre-feet per day, and acre-foot is equal to 43560 cubic feet, the procedure would be:

1. Set the volume unit to ACFT.

2. Set the base volume unit to ft3.

3. Set the conversion factor to 43560.

4. Set the time base unit to Day.

5. Set the flow rate unit to AF/D.

9.2 Meter factors

Meter Factor is a gain adjustment that may be needed to adjust for installation effects caused by less than ideal straight run piping or if pairing the 8782 with an 8707 instead of with a MS sensor.

The procedure is very similar to Vortex and Coriolis and is entered as a flow multiplication factor of the range 0.2 to 1.8. Not all installations will require a Meter Factor and the 8782 will have a stable flow rate without a Meter Factor. If replacing an existing legacy transmitter, a Meter Factor will enable the 8782 to match the legacy transmitter flow reading if there is a discrepancy.

Performing an auto zero trim is recommended for best performance on the 8782. If an auto zero trim is performed at any time after entering a meter factor adjustment, the meter factor will need to be re-calculated and re-entered post auto zero trim or else accuracy could be impacted.

Meter Factor = Actual Flow Rate (from 8712H) / Current Flow Rate (From 8782)

Example:

• The known actual flow rate is 100 GPM.

• A newly installed transmitter reads a flow rate of 1150 GPM after auto zero.

Remedy:

1. Perform a Meter Factor calculation of 100/115 = 0.8696.

2. Enter a Meter Factor of 0.8696 into the transmitter.

Note

Four decimal places are available to avoid rounding errors.

Result:

• The transmitter now reads 100 GPM

9.3 Licensing and enabling

All advanced diagnostics are licensed by ordering option code MV or DS1. In the event that a diagnostic option is not ordered, advanced diagnostics can be licensed in the field through the use of a license key. Each transmitter has a unique license key specific to the diagnostic option code. A trial license is also available to enable the advanced diagnostics. This temporary functionality will be automatically disabled after 30-days or when power to the transmitter is cycled, whichever occurs first. This trial code can be used a maximum of three times per transmitter. See the detailed procedures below for entering the license key and enabling the advanced diagnostics. To obtain a permanent or trial license key, contact an Emerson representative.

This parameter shows the current empty pipe value. This is a read-only value. This number is a unit-less number and is calculated based on multiple installation and process variables such as sensor type, line size, process fluid properties, and wiring. If the empty pipe value exceeds the empty pipe trigger level for a specified number of updates, then the empty pipe diagnostic alert will activate.

Empty pipe trigger level is the threshold limit that the empty pipe value must exceed before the empty pipe diagnostic alert activates. The default setting from the factory is

100.

Empty pipe (EP) counts

LOI menu path Diagnostics → Basic Diag → Empty Pipe → EP Counts

Limits: 2 to 50

Empty pipe counts is the number of consecutive updates that the transmitter must receive where the empty pipe value exceeds the empty pipe trigger level before the empty pipe diagnostic alert activates. The default setting from the factory is 5.

9.4.2 Optimizing tunable empty pipe

The tunable empty pipe diagnostic is set at the factory to properly diagnose most applications. If this diagnostic activates, the following procedure can be followed to optimize the empty pipe diagnostic for the application.

1. Record the empty pipe value with a full pipe condition.

Full reading = 0.2

2. Record the empty pipe value with an empty pipe condition.

Empty reading = 80.0

3. Set the empty pipe trigger level to a value between the full and empty readings.

For increased sensitivity to empty pipe conditions, set the trigger level to a value closer to the full pipe value.

Set the trigger level to 25.0

4. Set the empty pipe counts to a value corresponding to the desired sensitivity level

for the diagnostic.

For applications with entrained air or potential air slugs, less sensitivity may be desired.

Set the counts to 10

9.5 Electronics temperature

The transmitter continuously monitors the temperature of the internal electronics. If the measured electronics temperature exceeds the operating limits of –40 to 140 °F (–40 to 60 °C) the transmitter will go into alarm and generate an alert.

9.6 Ground/wiring fault detection

The transmitter continuously monitors signal amplitudes over a wide range of frequencies. For the ground/wiring fault detection diagnostic, the transmitter specifically looks at the signal amplitude at frequencies of 50 Hz and 60 Hz which are the common AC cycle frequencies found throughout the world. If the amplitude of the signal at either of these frequencies exceeds 5 mV, that is an indication that there is a ground or wiring issue and that stray electrical signals are getting into the transmitter. The diagnostic alert will activate indicating that the ground and wiring of the installation should be carefully reviewed.

The ground/wiring fault detection diagnostic provides a means of verifying installations are done correctly. If the installation is not wired or grounded properly, this diagnostic will activate and deliver an alert. This diagnostic can also detect if the grounding is lost overtime due to corrosion or another root cause.

Line noise

LOI menu path Diagnostics → Variables → Line Noise

The line noise parameter shows the amplitude of the line noise. This is a read-only value. This number is a measure of the signal strength at 50/60 Hz. If the line noise value exceeds 5 mV, then the ground/wiring fault diagnostic alert will activate.

9.7 High process noise detection

The high process noise diagnostic detects if there is a process condition causing an unstable or noisy reading that is not an actual flow variation. A common cause of high process noise is slurry flow, like pulp stock or mining slurries. Other conditions that cause this diagnostic to activate are high levels of chemical reaction or entrained gas in the liquid. If unusual noise or flow variation is seen, this diagnostic will activate and deliver an alert. If this situation exists and is left without remedy, it will add additional uncertainty and noise to the flow reading.

The high process noise diagnostic can be turned on or off as required by the application. If the advanced diagnostics suite 1 (DS1 Option) was ordered, then the high process noise diagnostic will be turned on. If DS1 was not ordered or licensed, this diagnostic is not available.

High process noise parameters

The high process noise diagnostic has two read-only parameters. It does not have any configurable parameters. This diagnostic requires that flow be present in the pipe and the velocity be greater than1 ft/s (0.3 m/s). The low and high frequency signal values depend on the line size.

Low frequency signal to noise ratio (SNR)

LOI menu path

This parameter shows the value of the signal to noise ratio at the coil drive low frequency. This is a read-only value. This number is a measure of the signal strength at low frequency relative to the amount of process noise. If the transmitter is operating in low frequency mode, and the signal to noise ratio remains below [25] for one minute, then the high process noise diagnostic alert will activate.

9.8 Coated electrode detection

The coated electrode detection diagnostic provides a means of monitoring insulating coating buildup on the measurement electrodes. If coating is not detected, buildup over time can lead to a compromised flow measurement. This diagnostic can detect if the electrode is coated and if the amount of coating is affecting the flow measurement. There are two levels of electrode coating.

• Limit 1 indicates when coating is starting to occur, but has not compromised the flow

measurement.

9.9 4-20 mA loop verification

The 4-20 mA loop verification diagnostic provides a means of verifying the analog output loop is functioning properly. This is a manually initiated diagnostic test. This diagnostic checks the integrity of the analog loop and provides a health status of the circuit. If the verification does not pass, this will be highlighted in the results given at the end of the check.

The 4-20 mA loop verification diagnostic is useful for testing the analog output when errors are suspected. The diagnostic tests the analog loop at five different mA output levels:

• 4 mA

• 12 mA

• 20 mA

• Low alarm level

• High alarm level

9.10 Smart Meter Verification

The Smart Meter Verification diagnostic provides a means of verifying the flowmeter is within calibration without removing the sensor from the process. This diagnostic test provides a review of the transmitter and sensor's critical parameters as a means to document verification of calibration. The results of this diagnostic provide the deviation amount from expected values and a pass/fail summary against user-defined criteria for the application and conditions. The Smart Meter Verification diagnostic can be configured to run continuously in the background during normal operation, or it can be manually initiated as required by the application.

9.10.1 Sensor baseline parameters

The Smart Meter Verification diagnostic functions by taking a baseline sensor signature and then comparing measurements taken during the verification test to these baseline results.

The sensor signature describes the magnetic behavior of the sensor. Based on Faraday's law, the induced voltage measured on the electrodes is proportional to the magnetic field strength. Thus, any changes in the magnetic field will result in a calibration shift of the sensor. Having the transmitter take an initial sensor signature when first installed will provide the baseline for the verification tests that are done in the future. There are three specific measurements that are stored in the transmitter's non-volatile memory that are used when performing the calibration verification.

Coil circuit resistance

LOI menu path

The coil resistance is a measurement of the coil circuit health. This value is used as a baseline to determine if the coil circuit is still operating correctly.

Coil inductance (signature)

LOI menu path

The coil inductance is a measurement of the magnetic field strength. This value is used as a baseline to determine if a sensor calibration shift has occurred.

Electrode circuit resistance

LOI menu path

The electrode circuit resistance is a measurement of the electrode circuit health. This value is used as a baseline to determine if the electrode circuit is still operating correctly.

9.10.2 Establishing the sensor baseline

The first step in running the Smart Meter Verification test is establishing the reference baseline that the test will use as the baseline for comparison. This is accomplished by having the transmitter take a baseline of the sensor.

Reset baseline (re-signature meter)

LOI menu path Diagnostics → Advanced Diag → Meter Verif → Sensr Baseline

→ Reset Baseline

Having the transmitter take an initial sensor baseline when first installed will provide the comparison point for the verification tests that are done in the future. The sensor baseline should be taken during the start-up process when the transmitter is first connected to the sensor, with a full line, and ideally with no flow in the line. Running the sensor baseline procedure when there is flow in the line is permissible, but this may introduce some noise into the electrode circuit resistance measurement. If an empty pipe condition exists, then the sensor baseline should only be run for the coils.

Note

For high temperature applications, it is a best practice to take the sensor baseline when the process fluid and sensor have reached their normal operating temperature if that will be operating condition during test measurements.

9.10.3

Once the sensor baseline process is complete, the measurements taken during this procedure are stored in non-volatile memory to prevent loss in the event of a power interruption to the meter. This initial sensor signature is required for both manual and continuous Smart Meter Verification.

Recall values (recall last saved)

LOI menu path

In the event that the sensor baseline was reset accidentally or incorrectly, this function will restore the previously saved sensor baseline values.

Diagnostics → Advanced Diag → Meter Verif → Sensr Baseline → Recall Values

Smart Meter Verification test criteria

The Smart Meter Verification diagnostic provides the ability to customize the test criteria to which the verification must be tested. The test criteria can be set for each of the flow conditions discussed above.

No flow limit

LOI menu path

Set the test criteria for the no flow condition. The factory default for this value is set to five percent with limits configurable between one and ten percent. This parameter applies to manually initiated test only.

Continuous limit

LOI menu path

Set the test criteria for the continuous Smart Meter Verification diagnostic. The factory default for this value is set to five percent with limits configurable between two and ten percent. If the tolerance band is set too tightly, under empty pipe conditions or noisy flowing conditions, a false failure of the transmitter test may occur.
