Sensor Installation 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: • High-vibration lines with integrally mounted transmitters • Tropical/desert installations in direct sunlight • Outdoor installations in arctic climates Remote mounted transmitters may be installed in the control room to protect the electronics from the harsh environment and to provide easy access for configuration or service.
Page 17
Sensor Installation Figure 3-2: Flow direction arrow 3.2.4 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.
Sensor Installation 3.2.5 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 3-4.

Page 20
Sensor Installation 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.

Advanced Diagnostics Configuration 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.
Page 128
Advanced Diagnostics Configuration with a full line, and ideally with no flow in the line. Running the sensor signature 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 signature should only be run for the coils.
Advanced Diagnostics Configuration Set the test criteria for the empty pipe 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 Diagnostics >...
Advanced Diagnostics Configuration Empty pipe Run the SMART Meter Verification test with an empty pipe. Running the SMART Meter Verification test under this condition provides the ability to verify the magnetic flowmeter health with an empty pipe. Running the verification diagnostic under empty pipe conditions will not check the electrode circuit health.
Advanced Diagnostics Configuration 9.11.1 Test scope Continuous SMART Meter Verification can be configured to monitor the sensor coils, electrodes, analog output, and transmitter calibration, All of these parameters can be individually enabled or disabled. These parameters apply to continuous SMART Meter Verification only.

Digital Signal Processing 10.4 High process noise diagnostic The transmitter continuously monitors signal amplitudes over a wide range of frequencies. For the high process noise diagnostic, the transmitter specifically looks at the signal amplitude at frequencies of 2.5 Hz, 7.5 Hz, 32.5 Hz, and 42.5 Hz. The transmitter uses the values from 2.5 and 7.5 Hz and calculates an average noise level.
Page 142
Digital Signal Processing 10.5.2 Auto zero LOI menu path Diagnostics > Trims > Auto Zero To ensure optimum accuracy when using 37 Hz coil drive mode, there is an auto zero function that should be initiated. When using 37 Hz coil drive mode it is important to zero the system for the specific application and installation.
Page 143
Digital Signal Processing 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 and activates signal processing at the factory set default values. When using filter mode, perform an auto zero with no flow and a full sensor.
Digital Signal Processing Time limit LOI menu path Detailed Setup > Signal Processing > Main Config DSP > Time Limit 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.

Prerequisites Prior to installing the replacement electronics stack, it is important to verify that the transmitter housing you have is of the correct design to accept the Revision 4 electronics.
Maintenance 11.5 Replacing a socket module/terminal block The socket module connects the sensor adapter to the transmitter. There are two versions of the socket module - one for integral mount transmitters and one for remote mount transmitters. The socket module is a replaceable component. To remove the socket module, loosen the two mounting screws and pull up on the socket module from the base.

Maintenance Reconnect remote cabling, replace the junction box cover on the sensor, and connect power. 11.6 Trims Trims are used to calibrate the analog loop, calibrate the transmitter, re-zero the transmitter, and calibrate the transmitter with another manufacturer's sensor. Proceed with caution whenever performing a trim function.
Page 156
Maintenance 11.6.3 Digital trim LOI menu path Diagnostics > Trims > Digital Trim Digital trim is the function by which the factory calibrates the transmitter. This procedure is rarely needed by users. It is only necessary if the transmitter is suspected to be no longer accurate.
Maintenance The flow rate reading after warm-up should be between 29.97 (9.1 m/s) and 30.03 ft/s (9.2 m/s). If the reading is within the range, return the transmitter to the original configuration parameters. If the reading is not within this range, initiate a digital trim with the LOI or Handheld Communicator.
Consider all sources when identifying a problem in the system. If the problem persists, consult the local Rosemount representative to determine if the material should be returned to the factory. Emerson offers several diagnostics that aid in the troubleshooting process.

This capability can provide additional information about the installation, the process, and the health of the sensor.
Implementing a Universal Transmitter Method 2: Involves the conversion of the existing sensor calibration number / meter factors to an equivalent Rosemount 16-digit calibration number. Accuracy of the meter using this methodology is estimated to be in the range of 2-3%. Contact the Rosemount technical support for more information on this method or to determine a calibration number for the existing sensor.
