Rosemount 8732

SYSTEM DESCRIPTION The Rosemount

sensor and transmitter, and measures volumetric flow rate by detecting the velocity of a conductive liquid that passes through a magnetic field.

There are four Rosemount magnetic flowmeter sensors:

• Flanged Rosemount 8705

• Flanged High-Signal Rosemount 8707

• Wafer-Style Rosemount 8711

• Sanitary Rosemount 8721

There are two Rosemount magnetic flowmeter transmitters:

• Rosemount 8712

• Rosemount 8732

The sensor is installed in-line with process piping — either vertically or horizontally. Coils located on opposite sides of the sensor create a magnetic field. Electrodes located perpendicular to the coils make contact with the process fluid. A conductive liquid moving through the magnetic field generates a voltage at the two electrodes that is proportional to the flow velocity.

The transmitter drives the coils to generate a magnetic field, and electronical ly conditions the voltage detected by the electrodes to provide a flow signal. T he transmitter can be integrally or remotely mounted from the sensor.

This manual is designed to assist in the installation and ope ration of the Rosemount 8732 Magnetic Flowmeter Transmitter and the Rosemount 8700 Series Magnetic Flowmeter Sensors.

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.

To avoid possible damage to the sensor liner ends, do not use metallic or spiral-wound gaskets. If frequent removal is anticipated, take precautions to protect the liner ends. Short spool pieces attached to the sensor ends are often used for protection.

Correct flange bolt tightening is crucial for proper sensor operation and life. All bolts must be tightened in the proper sequence to the specified torque limits. Failure to observe these instructions could result in severe damage to the sensor lining and possible sensor replacement.

Emerson Process Management can supply lining protectors to prevent liner damage during removal, installation, and excessive bolt torquing.

Hardware Jumpers/Switches

Conduit Ports and Connections

The 8732 Profibus PA electronics board is equipped with two user-selectable hardware switches. These switches do not have any functionality and should be left in the default positions as listed below:

Simulate Enable OFF Transmitter Security OFF

Changing the switch position will have no effect on the functionality of the electronics.

Both the sensor and transmitter junction boxes have ports for 1/2-inch NPT conduit connections, with optional CM20 and PG 13.5 adapter connections available. These connections should be made in accordance with national, local or plant electrical codes. Unused ports should be sealed with metal plugs and PTFE tape or other thread sealant. Connections should also be made in accordance with area approval requ ire m en ts, see example s be low for details. Proper electrical installation is necessary to prevent errors due to electrical noise and interference. Separate conduits are not necessary for the coil drive and signal cables connecting the transmitter to the sensor, but a dedicated conduit line between each transmitter and sensor is required. A shielded cable must be used.

Example 1: Installing flanged sensors into an IP68 area. Sensors must be installed with IP68 cable glands and cable to maintain IP68 rating. Unused conduit connections must be properly sealed to prevent water ingress. For added protection, dielectric gel can be used to pot the sensor terminal block. Consult technical document 00840-0100-4750 when installing meters into an IP68 installation.

Example 2: Installing flowmeters into explosion proof/flameproof areas. Conduit connections and conduit must be rated for use in the hazardous area to maintain flowmeter approval rating. Consult Appendix B: of this manual for

installation requirements for hazardous areas.

Conduit Cables Run the appropriate size cable through the conduit connections in your

magnetic flowmeter system. Run the power cable from the power source to the transmitter . Do n ot run power cab les and outpu t signal cables in the same conduit. For remote mount installations, run the coil drive and electrode cables between the flowmeter and transmitter. Refer to Electrical Considerations for wire type. Prepare the ends of the coil drive and electrode cables as shown in Figure 2-2. Limit the unshielded wire length to 1-in. on both the electrode and coil drive cables. Excessive lead length or failure to connect cable shields can create electrical noise resulting in unstable meter readings.

SENSOR CONNECTIONS This section covers the steps required to physically install the transmitter

including wiring and calibration.

Rosemount Sensors To connect the transmitter to a non-Rosemount sensor, refer to the

appropriate wiring diagram in “Universal Sensor Wiring Diagrams” on page E-1. The calibration procedure listed is not required for use with Rosemount sensors.

Transmitter to Sensor Wiring

Figure 2-7. Conduit Preparation

Correct Incorrect

Flanged and wafer sensors have two conduit ports as shown in Figur e 2-7. Either one may be used for both the coil drive and electrode cables. Use the stainless steel plug that is provided to seal the unused conduit port. Use PTFE tape or thread sealant appropriate for the installation when sealing the conduit.

A single dedicated conduit run for the coil drive and electrode cables is needed between a sensor and a remote transmitter. Bundled cables in a single conduit are likely to create interference and noise problems in your system. Use one set of cables per conduit run. See Figure 2-7 for proper conduit installation diagram and Table 2-2 for recommended cable. For integral and remote wiring diagrams refer to Figure 2-9.

Rosemount recommends using the combination signal and coil drive for N5, E5 approved sensors for optimum performance.

Remote transmitter installations require equal lengths of signal and coil drive cables. Integrally mounted transmitters are factory wired and do not require interconnecting cables.

Lengths from 5 to 1,000 feet (1.5 to 300 meters) may be specified, and will be shipped with the sensor.

Conduit Cables Run the appropriate size cable through the conduit connections in your

magnetic flowmeter system. Run the power cable from the power source to the transmitter. Run the coil drive and electrode cables between the sensor and transmitter .

Prepare the ends of the coil drive and electrode cables as shown in Figure 2-8. Limit the unshielded wire length to 1-inch on both the electrode and coil drive cables.

NOTE

Excessive lead length or failure to connect cable shields ca n create electrical noise resulting in unstable meter readings.

This section covers basic operation, software functionality, and basic configuration procedures for the Rosemount 8732E Magnetic Flowmeter Transmitter with Profibus PA. For more information about the Profibus PA technology and the function blocks used in the transmitter, refer to Appendix F: Physical Block and Appendix G.

Calibration Rosemount sensors are wet calibrated at the factory. They do not need

further calibration during installation. Each Profibus PA configuration tool or host device has a different way of

displaying and performing configurations. Some will use Device Descriptions (DD) and DD Methods to make configuring and displaying data consistent across host platforms. There is no requirement that a configuration tool or host support these features. This section describes how to reconfigure the device manually.

QUICK START-UP Once the magnetic flowmeter system is installed and communication is

established, configuration of the transmitter must b e completed. The st andard transmitter configuration, without Option Code C1, Custom Configuration, is shipped with the following parameters:

Engineering Units: ft/s Sensor Size: 3-in. Sensor Calibration Number: 100000501000000

Sensor Calibration Number

A unique sensor calibration number, imprinted on the sensor tag, enables any Rosemount sensor to be used with any Rosemount transmitter without further calibration. Rosemount flow lab tests determine individual sensor output characteristics. The characteristics are identified by a 16-digit calibration number . In a Profibus PA environment, the 8732E can be configured using an 8732E Profibus P A LOI or a Simatic PDM. Please see Section 4 for 8732E PA LOI and PDM information.

The calibration number is more than a correction factor, or K- factor, for the sensor. The first five digits represent the low frequency gain. The ninth through thirteenth digits represent the high frequency ga in. Both nu mbers are normalized from an ideal number of 10000. Standard configurations use the low frequency gain, but in noisy applications it may be worthwhile to switch to the higher frequency. An additional transmitter procedure, called Auto Zero, is recommended to perform at the higher coil drive frequency. The seventh and eighth digits represent the zero offset at both frequencies where the nominal value is 50. Empty pipe functionality is a transmitter feature that is controlled by a parameter in the transducer block. To turn off this feature, see Appendix C.

ASSIGNING DEVICE T AG AND NODE ADDRESS

The 8732E Magnetic Flowmeter Tr ansmitter is shipped with a blank tag. The device is shipped with a default address of 126.

If the tag or address needs to be changed, use the features of the configuration tool. The tools do the following:

• Change the tag to a new value.

• Change the address to a new address.

BASIC SETUP AI Block The Analog Input (AI) function block processes field device measurements

and makes them available to the master. The output value from the AI block is in engineering units and contains a status indi cating the quality of the measurement. The measuring device may have several measurements or derived values available in different channels. Use the channel number to define the variable that the AI block processes. The 8732E transmitter only supports “Flow” as AI Block variable.

Upper Range Value This parameter set the flow rate in engineering units that corresponds to

100% flow. This parameter is configured in the Transducer Block. The Upper Range Value can be set for both forward or reverse flow rates.

Flow in the forward direction is represented by positive values and flow in the reverse direction is represented by negative values. The URV can be any value from –43.3 ft/s to +43.3 ft/s (-13.2 m/s to +13.2 m/s), as long as it is at least 1 ft/s (0.3 m/s) from the lower range value (LRV). The URV can be set to a value less than the lower range value.

NOTE

Line size and density must be selected prior to configuration of URV and LRV .

Lower Range Value This parameter sets the flow rate in engineering units that correspo nds to 0%

flow. This pa rameter is configured in the Transducer Block. Set the lower range value (LRV) to change the size of the range (or span)

between the URV and LRV. Under normal circumstances, the LRV should be set to a value near the minimum expected flow rate to maximize resolution. The LRV must be between –43.3 ft/s to +43.3 ft/s (-13.2 m/s to +13.2 m/s).

NOTE

Line size and density must be selected prior to configuration of URV and LR V.

The minimum allowable span between the URV and LRV is 1 ft/s (0.3 m/s). Do not set the LRV within 1 ft/s (0.3 m/s) of the URV. For example, if the URV is set to 15.67 ft/s (4.8 m/s) and if the desired URV is greater than the LRV, then the highest allowable LRV setting would be 14.67 ft/s (4.5 m/s). If the desired URV is less than the LRV, then the lowest allowable LRV would be

16.67 ft/s (5.1 m/s).

Calibration Number The sensor calibration number is a 16-digit number used to identify sensors

calibrated at the Rosemount factory. The calibration number is also printed inside the sensor terminal block or on the sensor name plate. The number provides detailed calibration information to the Rosemount 8732. To function properly within accuracy specifications, the number stored in the transmitter must match the calibration number on the sensor exactly. This parame te r is configured in the Transducer Block.

NOTE

Sensors from manufacturers other than Rose m ou nt Inc. can als o be calibrated at the Rosemount factory. Check the sensor for Rosemount calibration tags to determine if a 16-digit sensor calibration number exists for your sensor.

Be sure the calibration number reflects a calibration to a Rosemount reference transmitter. If the calibration number was generated by a means other than a certified Rosemount flow lab, accuracy of the system may be compromised.

If your sensor is not a Rosemount sensor and was not calibrated at the Rosemount factory, contact your Rosemount representative for assistance.

If your sensor is imprinted with an eight-digit number or a k-factor, check in the sensor wiring compartment for the sixteen-digit calibration number. If there is no serial number, contact the factory for a proper conversion.

INTRODUCTION This section contains information for advanced configuration parameters and

diagnostics. The software configuration settings for the Rosem ount 8732 can be accessed

through an 8732 LOI or by using a Class 2 Master. Before operating the Rosemount 8732 in an actual installation, you should review all of the factory set configuration data to ensure that they reflect the current application.

LOCAL OPERATOR INTERFACE

The optional Local Operator Interface (LOI) provides an operator communications centre for the 8732. By using th e LO I, th e op er at or can access some of the transmitter function - totalizer, basic set-up, or other functions under the detailed set-up. The LOI is integral to the transmitter electronics. If you need the added functio nality, or if your transmitter does not have an LOI, you must use a configuration tool such as the Simatic PDM tool.

Basic Features

The basic features of the LOI include 4 navigational arrow keys which are optical switches that are used to access the menu structure. See Figure below:

Class 2 Masters There are a number of available PROFIBUS configuration tools. These Class

2 Masters are manufacturer-independent tools for the operation, configuration, maintenance, and diagnosis of intelligent field devices. Device descriptor based Class 2 Masters allow 100% configuration capability on the 8732E Profibus PA transmitter.

Class 2 Masters always need to be connected to the DP segment. They cannot be directly connected to a PA segment.

DIAGNOSTICS Diagnostics are used to verify that the transmitter is functioning properly, to

assist in troubleshooting, to identify potential causes of error messages, and to verify the health of the transmitter and sensor. All the diagnostic test can be initiated through the use of a Class 2 Master. Some diagnostics can be accessed using the LOI.

Rosemount offers several different diagnostic suites providing various functionality.

Rosemount 8732

August 2010

Trims Trims are used to calibrate the transmitter, re-zero the transmitter, and

calibrate the transmitter with another manufacturer’s sensor. Proceed with caution whenever performing a trim function.

Electronics Trim

Electronics trim is the function by which the factory calibrates the transmitter. This procedure is rarely needed by customers. It is only necessary if you suspect the Rosemount 8732E is no longer accurate. A Rosemount 8714 Calibration Standard is required to complete an Electronics trim. Attempting an Electronics trim without a Rosemount 8714 Calibration Standard may result in an inaccurate transmitter or an error message. Electronics trim must be performed only with the coil drive mode set to 5 Hz and with a nominal sensor calibration number stored in the memory.

NOTE

Attempting an Electronics trim without a Rosemount 8714 may result in an inaccurate transmitter, or an “ELECTRONICS TRIM FAILURE” message may appear. If this message occurs, no values were changed in the transmitter. Simply power down the Rosemount 8732E to clear the message.

To simulate a nominal sensor with the Rosemount 8714, you must change the following parameters in the Rosemount 8732E:

1. Sensor Calibration Number—1000015010000000

2. Units—ft/s

3. Coil Drive Frequency - 5 Hz

The instructions for changing the Sensor Calibration Number and Units are located in “Flow Units” on page 3-7. Instructions for changing the Coil Drive Frequency can be found on page 4-14 in this section.

Set the loop to manual, if necessary , before you begin. Complete the following steps:

1. Power down the transmitter.

2. Connect the transmitter to a Rosemount 8714 Calibration Standard.

3. Power up the transmitter with the Rosemount 8714 connected and read the flow rate. The electronics need about a 5-minute warm-up time to stabilize.

4. Set the 8714 calibrator to the 30 ft/s setting.

5. The flow rate reading after warm-up should be between 29.97 and

30.03 ft/s.

6. If the reading is within the range, return the transmitter to the original configuration parameters.

7. If the reading is not within this range, initiate an Electronics trim with the Profibus PA configuration tool. The Electronics trim takes about 90 seconds to complete. No transmitter adjustments are required.

Rosemount 8732

Universal Trim

The Universal Trim function enables the Rosemount 8732E to calibrate sensors that were not calibrated at the Rosemount factory. The function is activated as one step in a procedure known as in-process calibration. If your Rosemount sensor has a 16-digit calibration number, in-p rocess calib ration is not required. If it does not, or if your sensor is made by another manufactu rer, complete the following steps for in-process calibration.

1. Determine the flow rate of the process fluid in the sensor.

NOTE

The flow rate in the line can be determined by using another sensor in the line, by counting the revolutions of a centrifug al pump , or by pe rfo rm in g a bucket test to determine how fast a given volume is filled by the process fluid.

2. Complete the Universal Trim function.

3. When the routine is completed, the sensor is ready for use.

Auto Zero

The Auto Zero function initializes the transmitter for use with the 37 Hz coil drive mode only. Run this function only with the transmitter and sensor installed in the process. The sensor must be filled with process fluid at zero flow. Before running the Auto Zero function, be sure the coil drive mode is set to 37 Hz (Auto Zero will not run with the coil drive frequency set at 5 Hz).

Set the loop to manual if necessary and begin the Auto Zero procedure. The transmitter completes the procedure automatically in about 90 seconds. A symbol appears in the lower right-hand corner of the display to indicate that the procedure is running.

Master Reset

The master reset is a function that the user can execute to reset the device configuration to the default setting.

There are three types of Master Reset: Cold St art - Reset the device to a default configuration . The device address is

not changed. Warm Start - Restart the device. This reset function acts just like a power

cycle. None of the configuration parameters are changed. Reset Address - This reset changes the bus address of the device to the

default address of 126. This change happens immediately regardless of the state of data exchange the transmitter is in.

ADVANCED CONFIGURATION

In addition to the basic configuration options and the diagnostic information and controls, the 8732 has many advanced functions that can also be configured as required by the application .

DETAILED SETUP The detailed setup function provides access to other parameters within the

transmitter that can be configured such as coil drive frequency, output parameters, local display configuration, and other general information about the device.

Additional Parameters The additional parameters menu provides a means to configure optional

parameters within the 8732E transmitter.

Density Value

The density value is used to convert from a volumetric flow rate to a mass flow rate using the following equation:

= Qv  

Where: Q

is the mass flow rate

is the volumetric flow rate, and

 is the fluid density

NOTE

A density value is required to configure the flow units for mass flow rate measurement.

Sensor Range: High

This parameter is the maximum value that the PV Range value can be set to. This is the upper measuring limit of the transmitter and sensor.

Sensor Range: Low

This parameter is the minimum value that the PV Range value can be set to. This is the lower measuring limit of the transmitter and sensor.

Measurement Mode

Enable or disable the transmitter’s ability to read reverse flow. Measurement Mode allows the transmitter to read negative flow. This may

occur when flow in the pipe is going the negative direction, or when either electrode wires or coil wires are reversed. This also enables the totalizer to count in the reverse direction.

00809-0100-4665, Rev AA August 2010

Rosemount 8732

Signal Processing The 8732E contains several advanced functions that can be used to stabilize

erratic outputs caused by process noise. The signal processing menu contains this functionality. Below is sample PDM screen shot of Signal Processing.

Operating Mode (Operation)

The Operating Mode should be used only when the signal is noisy and gives an unstable output. Filter mode automatically uses 37 Hz coil drive mode an d activates signal processing at the factory set default values. When using filter mode, perform an auto zero with no flow and a full sensor. Either of the parameters, coil drive mode or signal processing, may still be changed individually. T urning Signal Processing off or changing the coil drive frequency to 5 Hz will automatically change the Operating Mode from filter mode to normal mode.

SP Control

When ON is selected, the Rosemount 8732E output is derived using a running average of the individual flow inputs. Signal processing is a software algorithm that examines the quality of the electrode signal against user-specified tolerances. This average is updated at the rate of 10 samples per second with a coil drive frequency of 5 Hz, and 75 samples per second with a coil drive frequency of 37 Hz. The three parameters that make up signal processing (number of samples, maximum percent limit, and time limit) are described below.

Number of Samples

0 to 125 Samples The number of samples function sets the amount of time that inputs are

collected and used to calculate the average value. Each second is divided into tenths (1/10) with the number of samples equaling the number of 1/10 second increments used to calculate the average.

For example, a value of: 1 averages the inputs over the past 1/10 second 100 averages the inputs over the past 10 second s

Percent of Rate

0 to 100 Percent The maximum percent limit is a tolerance band set up on either side of the

running average. The percentage value refers to deviation from the running average. For example, if the running average is 100 gal/min, and a 2 percent maximum limit is selected, then the acceptable range is from 98 to 102 gal/min.

V alues within the limit are accepted while values out side the limit are analyzed to determine if they are a noise spike or an actual flow change.

4-13

Rosemount 8732

Reference Manual

00809-0100-4665, Rev AA

August 2010

Time Limit

0 to 256 Seconds The time limit parameter forces the output and running average values to the

new value of an actual flow rate change that is outside the percent limit boundaries. It thereby limits response time to flow changes to the time limit value rather than the length of the running average.

For example, if the number of samples selected is 100, then the response time of the system is 10 seconds. In some cases this may be unacceptable. By setting the time limit, you can force the 8732E to clear the value of the running average and re-establish the output and average at the new flow rate once the time limit has elapsed. This parameter limits the response time added to the loop. A suggested time limit value of two seconds is a good starting point for most applicable process fluids. The selected signal processing configuration may be turned ON or OFF to suit your needs.

Coil Drive Frequency

Coil drive frequency allows pulse-rate selection of the sensor coils.

5 Hz

The standard coil drive frequency is 5 Hz, which is sufficient for nearly all applications.

37 Hz

If the process fluid causes a noisy or unstable output, increase the coil drive frequency to 37 Hz. If the 37 Hz mode is selected, perform the auto zero function with no flow and a full sensor.

Low Flow Cutoff

Low flow cutoff allows you to specify the flow rate, between 0.01 and 38.37 feet per second, below which the outputs are driven to zero flow. The units format for low flow cutoff cannot be changed. It is always displ ayed as feet per second regardless of the format selected. The low flow cutof f value applies to both forward and reverse flows.

Device Info Information variables are used for identification of flowmeters in the field and

to store information that may be useful in service situations. Information variables have no effect on flowmeter output or process variables.

Device ID

This function displays the Device ID of the transmitter. This is one piece of information required to generate a license code to enable diagnostics in the field.

PV Sensor S/N

The PV sensor serial number is the serial number of the sensor connected to the transmitter and can be stored in the transmitter configuration for future reference. The number provides easy identification if the sensor needs servicing or for other purposes.

4-14

Sensor Tag

Sensor tag is the quickest and shortest way of identifyin g and distinguishing between sensors. Sensors can be tagged according to th e requirements of your application. The tag may be up to eight characters long.

SENSOR MOUNTING Physical mounting of a sensor is similar to installing a typical section of pipe.

Conventional tools, equipment, and accessories (bolts, gaskets, and grounding hardware) are required.

Upstream/Downstream Piping

Figure 5-2. Upstream and Downstream Straight Pipe Diameters

To ensure specification accuracy over widely varying process conditions, install the sensor a minimum of five straight pipe diameters upstream and two pipe diameters downstream from the electrode plane (see Figure 5-2).

Sensor Orientation The sensor should be installed in a position that ensures the sensor remains

full during operation. Figures 5-3, 5-4, and 5-5 show the proper sensor orientation for the most common installations. The following orientations ensure that the electrodes are in the optimum plane to minimize the ef fects of entrapped gas.

Vertical installation allows upward process fluid flow and is generally preferred. Upward flow keeps the cross-sectional area full, regardless of flow rate. Orientation of the electrode plane is unimportant in vertical installations. As illustrated in Figures 5-3 and 5-4, avoid downward flows where back pressure does not ensure that the se nsor remains full at all times.

Figure 5-3. Vertical Sensor Orientation

Installations with reduced straight runs from 0 to five pipe diameters are possible. In reduced straight pipe run installations, performance will shift to as much as 0.5% of rate. Reported flow rates will still be highly repeatable.

Horizontal installation should be restricted to low piping sections that are normally full. Orient the electrode plane to within 45 degrees of horizontal in horizontal installations. A deviation of more than 45 degrees of horizontal would place an electrode at or near the top of the sensor thereby making it more susceptible to insulation by air or entrapped gas at the top of the sensor.

Gaskets The sensor requires a gasket at each of its connections to adjacent devices or

piping. The gasket material selected must be compatible with the process fluid and operating conditions. Metallic or spiral-wound gaskets can damage the liner. If the gaskets will be removed frequently, protect the liner ends. All other applications (including sensors with lining protectors or a grounding electrode) require only one gasket on each end connection, as shown in Figure 5-8. If grounding rings are used, gaskets are required on each side of the groundin g ring, as shown in Figure 5-9.

Figure 5-8. Gasket Placement

Figure 5-9. Gasket Placement with Non-attached Grounding Rings

Flange Bolts Suggested torque values by sensor line size and liner type are listed in Table

5-1 on page 5-8 for ASME B16.5 (ANSI) flanges and Table 5-2 and Table 5-3 for DIN flanges. Consult the factory for other flange ratings. Tighten flange bolts in the incremental sequence as shown in Figure 5- 10. See Table 5-1 and Table 5-2 for bolt sizes and hole diameters.

NOTE

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

1. Snug left

2. Snug right

3. Tighten left

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

Always check for leaks at the flanges after tightening the flange bolts. Failure to use the correct flange bolt tightening methods can result in severe dam age. All sensors require a second torquing 24 hours after initial flange bolt tightening.

For sensors with ANSI 600# full rated, 900#, 1500#, and 2500# flanges, the liner is protected from over-compression by the flange design. Standard flange torque specifications as determined by ANSI and ASME should be followed. No special precaution is required to prevent liner damage caused by over torquing. Bolt tightening procedures laid out in this Quick Installation Guide must still be followed.

Alignment and Bolting

1. On 11/2 - through 8-inch (40 through 200 mm) line sizes, place centering rings over each end of the sensor. The smaller line sizes,

0.15- through 1-inch (4 through 25 mm), do not require centering rings.

2. Insert studs for the bottom side of the sensor between the pipe flanges. Stud specifications are listed in Table 5-4. Using carbon

steel bolts on smaller line sizes, 0.15- through 1-inch (4 through 25 mm), rather than the required stainless steel bolts, will degrade performance.

GROUNDING Process grounding the sensor is one of the most important details of sensor

installation. Proper process grounding ensures that th e transmitter amplifier is referenced to the process. This creates the lowest noise environment for the transmitter to make a stable reading. Use Table 5-6 to determine which grounding option to follow for proper installation.

5-12

Reference Manual

00809-0100-4665, Rev AA August 2010

NOTE

Consult factory for installations requiring cathodic protection or situations where there are high currents or high potential in the process.

The sensor case should always be earth grounded in accordance with national and local electrical codes. Failure to do so may impair the protection provided by the equipment. The most effective grounding method is direct connection from the sensor to earth ground with minimal impedance.

The Internal Ground Connection (Protective Ground Connection) located in side the junction box is the Internal Ground Connection screw. This screw is identified by the ground symbol:

PROCESS LEAK PROTECTION (OPTIONAL)

Standard Housing Configuration

The Rosemount 8705 and 8707 High-Signal Sensor housing is fabricated from carbon steel to perform two separate functions. First, it provides shielding for the sensor magnetics so that external disturbances cannot interfere with the magnetic field and thus affect the flow measu re m en t. Second, it provides the physical protection to the coils and other internal components from contamination and physical d amage that might occur in an industrial environment. The housing is completely welded and gasket-free.

The three housing configurations are identified by the W0, W1, or W3 in the model number option code when ordering. Below are brief description s of each housing configuration, which are followed by a more detailed overview.

• Code W0 — sealed, welded coil housing (standard configuration)

• Code W1 — sealed, welded coil housing with a relief valve capable of venting fugitive emissions to a safe location (additional plumbing from the sensor to a safe area, installed by the user, is required to vent properly)

• Code W3 — sealed, welded coil housing with separate electrode compartments capable of venting fugitive emissions (additional plumbing from the sensor to a safe area, installed by the user, is required to vent properly)

The standard housing configuration is identified by a code W0 in the model number. This configuration does not provide separate electrode compartments with external electrode access. In the even t of a pr oc es s leak, these models will not protect the coils or other sensitive areas around the sensor from exposure to the pressure fluid (Figure 5-17).

Rosemount 8732

Relief Valves The first optional configuration, identified by the W1 in the model number

option code, uses a completely welded coil housing. This configuration does not provide separate electrode compartments with external electrode access. This optional housing configuration provides a relief valve in the housing to prevent possible overpressuring caused by damage to the lining or other situations that might allow process pressure to enter the housing. The relief valve will vent when the pressure inside the sensor housing exceeds 5 psi. Additional piping (provided by the user) may be connecte d to this relief valve to drain any process leakage to safe containment (see Figure 5-18).

Figure 5-18. Coil-Housing Configuration — Standard Welded Housing With Relief Valve (Option Code W1)

Process Leak Containment

The second optional configuration, identified as option code W3 in the model number, divides the coil housing into three compartments: one for each electrode and one for the coils. Should a damaged liner or electrode fault allow process fluid to migrate behind the electrode seal s, the fluid is contained in the electrode compartment. The sealed electrode compartment prevents the process fluid from entering the coil compartm ent wh er e it w oul d da m age the coils and other internal components.

The electrode compartments are designed to contain the process fluid at full line pressure. An o-ring sealed cover provides access to each of the electrode compartments from outside the se nsor; drain port s are provided in ea ch cover for the removal of fluid.

NOTE

The electrode compartment could contain full line pressure and it must be depressurized before the cover is removed.

SAFETY INFORMATION

Failure to follow these installation guidelines could result in death or serious injury: Installation and servicing instructions are for use by qualified personnel only. Do not perform

Do not connect a Rosemount 8732 to a non-Rosemount sensor that is located in an explosive atmosphere.

Mishandling products exposed to a hazardous substance may result in death or serious injury. If the product being returned was exposed to a hazardous substance as defined by OSHA, a copy of the required Material Safety Data Sheet (MSDS) for each hazardous substance identified must be included with the returned goods.

The 8732 performs self diagnostics on the entire magnetic flowmeter system: the transmitter, the sensor, and the interconnecting wiring. By sequentially troubleshooting each individual piece of the magmeter system, it becomes easier to pin point the problem and make the appropriate adjustments.

If there are problems with a new magmeter installation, se e “In stallation Check and Guide” on page 6-2 for a quick guide to solve the most common installation problems. For existing magmeter installations, Table 6-4 lists the most common magmeter problems and corrective actions.

INSTALLATION CHECK AND GUIDE

Use this guide to check new installations of Rosemount magnetic flowmeter systems that appear to malfunction.

Before You Begin Transmitter

Apply power to your system before making the following transmitter checks.

1. Verify that the correct sensor calibration number is entered in the

transmitter. The calibration number is listed on the sensor nameplate.

2. Verify that the correct sensor line size is entered in the transmitter.

The line size value is listed on the sensor nameplate.

3. Verify that the function blocks are not in Out of Service mode.

4. Verify that the transmitter is functioning correctly by using the 8714i

Meter Verification diagnostic or the 8714D Calibration Reference Standard.

Sensor

Be sure that power to your system is removed before beginning sensor checks.

1. For horizontal flow installations, ensure that the electrodes remain

covered by process fluid. For vertical or inclined installations, ensure that the process fluid

is flowing up into the sensor to keep the electrodes covered by process fluid.

2. Ensure that the grounding straps on the sensor are connected to

grounding rings, lining protectors, or the adjacent pipe flanges. Improper grounding will cause erratic operation of the system.

Wiring for Remote Configurations

1. The signal wire and coil drive wire must be twisted shielded cable. Emerson Process Management, Rosemount division. recommends 20 AWG twisted shielded cable for the elec trodes and 14 AWG twisted shielded cable for the coils.

2. The cable shield must be connected at both ends of the electrode and coil drive cables. Connection of the signal wire shield at both ends is necessary for proper operation. It is recommended that the coil drive wire shield also be connected at both ends for maximum flowmeter performance

3. The signal and coil drive wires must be separate cables, unless Emerson Process Management specified combo cable is used. See Table 2-2 on page 2-11.

4. The single conduit that houses both the signal and coil drive cables should not contain any other wires.

Process Fluid

1. The process fluid conductivity should be 5 microsiemens (5 micro mhos) per centimeter minimum.

2. The process fluid must be free of air and gasses.

3. The sensor should be full of process fluid.

QUICK TROUBLESHOOTING

Step 1: Wiring Errors The most common magmeter problem is wiring between the sensor and the

transmitter in remote mount installations. The signal wire and coil drive wire must be twisted shielded cable: 20 AWG twisted shielded cable for the electrodes and 14 AWG twisted shielded cable for the coils. Ensure that the cable shield is connected at both ends of the electrode and coil drive cables. Signal and coil drive wires must have their own cable s. The single conduit that houses both the signal and coil drive cables should not contain any other wires. For more information on proper wir ing practices, refe r to “T ran smitter to Sensor Wiring” on page 2-11.

Step 2: Process Noise In some circumstances, process conditions rather than the magmeter can

cause the meter output to be unstable. Possible solutions for addressing a noisy process situation are given below. When the output attains the desired stability, no further steps are required.

Use the Auto Zero function to initialize the transmitter for use with the 37 .5 Hz coil drive mode only. Run this function only with the transmitter and sensor installed in the process. The sensor must be filled with process fluid with zero flow rate. Before running the auto zero function, be sure the coil drive mode is set to 37.5 Hz.

Step 3: Installed Sensor Tests

Set the loop to manual if necessary and begin the auto zero procedure. The transmitter completes the procedure automatically in about 90 seconds. A symbol appears in the lower right-hand corner of the display to indicate that the procedure is running.

1. Change the coil drive to 37.5 Hz. Complete the Auto Zero function, if possible (see “Coil Drive Frequency” on page 4-13).

2. Turn on Digital Signal Processing (see “Signal Processing” on page 4-25)

3. Increase the damping (see “Damping” on page 3-17).

If the preceding steps fail to resolve the process noise symptoms, consult your Rosemount sales representative about using a high-sig nal magnetic flowmeter system.

If a problem with an installed sensor is identified, Table 6-5 can assist in troubleshooting the sensor. Before performing any of the sensor tests, disconnect or turn off power to the transmitter. To interpret the results, the hazardous location certification for the sensor must be known. Applicable codes for the Rosemount 8705 are N0, N5, and KD. Applicable codes for the Rosemount 8707 are N0 and N5. Applicable codes for the Rosemount 8711 are N0, N5, E5, and KD. Always check the operation of test equipment before each test.

If possible, take all readings from inside the sensor junction box. If the sensor junction box is inaccessible, take measurements as close as possible. Readings taken at the terminals of remote-mount transmitters that are more than 100 feet away from the sensor may provide incorrect or inconclusive information and should be avoided. A sensor circuit diagram is provided in Figure 6-1 on page 6-9.

Step 4: Uninstalled Sensor Tests

An uninstalled sensor can also be used for sensor troubleshooting. To interpret the results, the hazardous location certification for the sensor must be known. Applicable codes for the Rosemount 8705 are N0, N5, and KD. Applicable codes for the Rosemount 8707 are N0 and N5. Applicable codes for the Rosemount 8711 are N0, N5, E5, and KD.

A sensor circuit diagram is provided in Figure 6-1. Take measurements from the terminal block and on the electrode head inside th e se nso r. The measurement electrodes, 18 and 19, are on opposite sides in the inside diameter. If applicable, the third grounding electrode is in between the other two electrodes. On Rosemount 8711 sensors, electrode 18 is near the sensor junction box and electrode 19 is near the bottom of the sensor (Figure 6-2). The different sensor models will have slightly different resistance readings. Flanged sensor resistance readings are in Table 6-6 while wafer sensor resistance readings are in Table 6-7.

Profibus PA Function Blocks

Physical Block - Slot 0

The Physical Block contains physical transmitter information, including available memory, manufacturer identification, device type, software tag, and unique identification.

Transducer Block - Slot 5

The transducer block calculates flow from the measured induced voltage and provides the flowrate input to the AI Block. The calculation includes information related to the calibration number, line size, and diagnostics.

Analog Input Block - Slot 1

The AI function block processes the measurement and makes it available to the Host system. The AI function block also allows filtering, alarming, and engineering unit changes. The 8732E T r ansmitter with Profibus PA digital fieldbus comes standard with one AI function block which is dedicated to flow.

Totalizer Block (3 blocks) - Slots, 2, 3, 4

The Totalizer function block allows for totalization of the flow signal. The 8732E Transmitter with Profibus PA digital fieldbus comes with 3 independent totalizer blocks. Each totalized value can be displayed on the Local Operator Interface of the device in addition to the Primary Variable.

Sensor Compensation

Rosemount sensors are flow-calibrated and assigned a calibration factor at the factory. The calibration factor is entered into the transmitter, enabling interchangeability of sensors without calculations or a compromise in standard accuracy.

8732E transmitters and other manufacturers’ sensors can be calibrated at known process conditions or at the Rosemount NIST-Traceable Flow Facility. Transmitters calibrated on site require a two-step procedure to match a known flow rate. This procedure can be found in the Operations Manual:
