Rosemount mass flow meter zero drift fault
Thread Content
Liquid ethylene mass flow meter, model: F300S426CRAZMZ1ZX, temperature: -35°C, pressure: 3 MPa, normal operating flow rate: 30 t/h. The flow meter experiences frequent zero-point drift; it has been checked that the parameter settings are correct, that the sensor drive and detection coils are functioning properly within the required resistance ranges, and no signs of gas-liquid entrainment or incomplete filling of the pipe have been detected. The specific cause has not been identified yet; anyone who is familiar with this type of issue or has encountered it please provide detailed explanations!
It is normal to have zero drift; the key is how much the drift is. The pipe stress should not be high; is there any vibration? How about the on-site grounding?

Increase the cut-off signal to avoid frequent zeroing.
