Table 10-9 Excessive drive gain causes and remedies
Cause Possible remedy
Excessive slug flow See Section 10.16.
Plugged flow tube Purge the flow tubes.
Cavitation or flashing Increase inlet or back pressure at the sensor.
If a pump is located upstream from the sensor, increase the distance
between the pump and sensor.
Drive board or module failure, cracked flow tube,
or sensor imbalance
Contact Micro Motion. See Section 10.3.
Mechanical binding at sensor Ensure sensor is free to vibrate.
Open drive or left pickoff sensor coil Contact Micro Motion. See Section 10.3.
Flow rate out of range Ensure that flow rate is within sensor limits.
Incorrect sensor characterization Verify characterization. See Section 6.2.
