ABB Mass Flowmeter FCM2000

Essentially maintenance is not required for the flowmeter sensor. The following items should be checked annually

- Ambient conditions (air circulation, humidity)

- Seal integrity of the process connections

- Cable entry points and cover screws

- Operational reliability of the auxiliary power feed, the lightning protection and the grounds

- The flowmeter sensor electrodes must be cleaned when the flowrate information on the transmitter changes when recording the identical flowrate volume. If the display shows a higher flowrate, the contamination is insulating. If the flowrate displayed is lower, the contamination results in a short-circuit.

- When cleaning the exterior of meters, make sure that the cleaning agent used does not corrode the housing surface and the seals.;
