12.1.1 Run an SMV test
Run an SMV test to ensure that your sensor has not experienced any physical or mechanical damage that
affects measurement accuracy.
•
If SMV results show that the meter has passed, then measurements meet specifications.
•
If SMV results show that the meter has failed, measurement may be affected.
•
If SMV results show that the meter has aborted, then either a problem occurred with the meter verification
test (e.g., process instability) or you stopped the test manually.
Prerequisites
For full capabilities, SMV must be licensed on your transmitter. If no license is active, you can still initiate SMV;
you will receive an indication as to whether the meter has passed or failed the SMV run.
Before running SMV for the first time, you must begin a first-time SMV run to establish the Field Reference
Point. The display and other interfaces will prompt you to do so if it has not yet been done.
The SMV test runs best when process conditions are stable. If conditions are too unstable, the test will abort.
To maximize process stability:
•
Maintain a constant fluid temperature and pressure.
•
Stop flow through the sensor.
•
Avoid changes to fluid composition, for example, two-phase flow or settling.
If you plan to use a fixed value during the SMV test, ensure that all affected control loops are prepared for the
interruption in process measurement. The test will run for approximately 140 seconds.
