Routine maintenance: only need to make periodic visual inspections of the instrument, check the environment around the instrument, remove dust and dirt, ensure that no water and other substances enter, check whether the wiring is in good condition, and check whether there are newly installed strong electromagnetic field equipment or newly installed wires near the instrument Cross-instrument. If the measuring medium easily contaminates the electrode or deposits in the measuring tube wall, it should be cleaned and cleaned regularly.

Fault finding: if the meter is found to work abnormally after the flowmeter has been put into operation or normal operation for a period of time, the external conditions of the flowmeter should be checked first, such as whether the power supply is good, whether the pipeline is leaking or in a state of partial pipe, whether there is any in the pipeline Whether air bubbles, signal cables are damaged, and whether the output signal of the converter (that is, the input circuit of the subsequent instrument) is open. Remember to dismantle and repair the flowmeter blindly.
