Checking process variables
Micro Motion suggests that you make a record of the process variables listed below, under normal
operating conditions. This will help you recognize when the process variables are unusually high or
low.
operating conditions. This will help you recognize when the process variables are unusually high or
low.
•
Flow rate
•
Density
•
Temperature
•
Tube frequency
•
Pickoff voltage
•
Drive gain
For troubleshooting, check the process variables under both normal flow and tubes-full no-flow
conditions. Except for flow rate, you should see little or no change between flow and no-flow
conditions. If you see a significant difference, record the values and contact Micro Motion customer
service for assistance.

Unusual values for process variables may indicate a variety of different problems. Table 10-4 lists
several possible problems and suggested remedies.
