Emerson 2200S Manuel D’Utilisation

110

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.

•

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.
