The maintenance of the electromagnetic flowmeter should follow a certain order, so as to avoid entering the misunderstanding of maintenance, causing unnecessary delays and losses.
Electromagnetic flowmeter maintenance in the end what steps to carry out is the best method?
Good quality electromagnetic flowmeters generally do not require daily maintenance, but if the measured medium is easy to adhere to or scale the inner wall of the electrode and the measuring tube, it is necessary to regularly clean the inner wall of the measuring tube and the electrode, taking care not to damage the lining and the electrode.
If your electromagnetic flowmeter fails, it is recommended that you can refer to the following order one by one to find, analyze the cause, troubleshoot.
1. Measure whether the medium in the tube is full, and whether there is scale on the lining and electrode;
2. Whether all cable connections are reliable;
3. Whether the grounding requirements are met, whether the excitation coil is short-circuited or disconnected, and whether it is insulated to the ground;
4. Whether the medium in the pipe leaks, whether the upstream and downstream valves are affected, and whether the installation position is appropriate;
5. Whether the surrounding environment interferes with the flow meter and whether the converter fails.
In addition, regarding the period of re-inspection of the electromagnetic flowmeter, it is recommended that the electromagnetic flowmeter be overhauled every two years, and users with higher accuracy requirements should be inspected annually.
