Electrode maintenance of electromagnetic flowmeter

It is only necessary to conduct a periodic visual inspection of the meter, check the surrounding environment of the meter, remove dust and dirt, ensure that no water and other substances enter, check whether the wiring is in good condition, and check whether there is a new strong electromagnetic field device near the meter or a newly installed wire across the meter. If the measuring medium is easy to contaminate the electrode or deposit and scale in the measuring tube wall, it should be cleaned regularly.
1. Before using the electromagnetic flowmeter, the electromagnetic flowmeter must be calibrated with a standard pH value solution. After calibration and before operation, everyone must pay attention to cleaning the electrodes of the electromagnetic flowmeter with distilled water first, and then cleaning the electrodes with the measuring solution.
2. If the electromagnetic flowmeter is not used, when removing the electrode of the electromagnetic flowmeter, everyone should be careful not to let the electrode's touch sensor collide with hard objects, otherwise, any damage will affect the use of the electrode.
3. After using the electromagnetic flowmeter, you should cover the electrode cover of the electromagnetic flowmeter, and put less saturated solution in it, as long as the bulb of the electrode is wet, but remember not to put it in distilled water soak.
4. Usually, keep the electrodes clean, and don’t short-circuit the output on both sides of it, otherwise it will make the measurement inaccurate and affect the use of the electromagnetic flowmeter.
In fact, there are still many ways to maintain the electrodes of the electromagnetic flowmeter. Everyone should pay more attention during use, and don't cause the electromagnetic flowmeter to be unable to use normally in the future because of a little negligence.
