It is never forgotten to know that electromagnetic water meters require frequent maintenance

  We meter people should know that electromagnetic water meters also need to be maintained frequently. As an meter person, as a user, we need to know that regular review and frequent maintenance are required. The following is a maintenance instruction, because most of the failures of electromagnetic water meters are caused by insulation degradation, electrode contamination or adhesion of foreign objects. Routine maintenance is important.

  Regular inspections should be carried out for routine maintenance. The inspection contents include: check whether the indication of the meter is normal; check whether the power supply of the meter is normal; check whether the meter body (connecting pipelines, lines) is leaked, damaged or corroded; check whether there is a new installation near the meter. Electromagnetic field equipment may have newly installed wires across the instrument; problems should be dealt with in time, and patrol inspection records should be made.

  At the same time, regular maintenance should be done, and the maintenance contents include:

  Zero point inspection of the whole machine: The measuring tube of the flow sensor is filled with liquid and has no movement. If the conditions are not met, the zero point inspection and adjustment of the whole machine can be abandoned, but the zero point inspection and adjustment of the converter can be performed independently. From a technical point of view, this has practical significance only after the sensor is checked and the insulation resistance of the excitation circuit and signal circuit of the sensor is normal (both including cables);

  Check the connection cable: mainly check the conduction and insulation resistance of each core of the signal line and the excitation line to see if they are all good; check the excitation power supply: judge whether the power supply is working normally by the electric meter;

  Instrument cleaning work: including sweeping dust and ensuring that the instrument is free of water and other substances. When the medium on the north side is easy to scale in the measuring tube and the electrode, it needs to be cleaned, but be careful not to damage the lining and the electrode; if there is an integrator, it needs to be reset periodically according to the situation.
