Electromagnetic flowmeter flow rate low reasons and solutions

1. The service life of the equipment is too long. The electromagnetic flowmeter is a device that is not easily damaged after long-term use. However, long-term use will also have an impact on the equipment, such as a reduction in the magnetic field. If the electromagnetic flowmeter has a long service life, its measurement accuracy will gradually decrease, resulting in a low flow rate. The solution is to replace the electromagnetic flowmeter with a new one, pay attention to the equipment life cycle, and check and replace the equipment regularly.

2. Electrode Blockage When the electromagnetic flowmeter is used for a certain period of time, the medium will be deposited on the electrodes, causing the electrodes to block, which will affect the measurement accuracy and cause the flow rate to be low. The solution is to clean the electrode regularly or replace it with ceramic electrode material.

3. Inaccurate measurement parameters The measurement accuracy of the electromagnetic flowmeter can be affected by external conditions such as temperature and humidity. If the measurement parameters used do not meet the actual situation, the flow rate will also be low. Solutions include replacing high-precision sensors, adjusting measurement parameters, or replacing the junction box. In summary, there are many reasons for the low flow rate of the electromagnetic flowmeter, but as long as the reasons can be found out and the problems are solved according to the reasons, the accuracy of the electromagnetic flowmeter can be guaranteed. At the same time, in order to avoid the occurrence of these problems, it is recommended that users regularly maintain, clean and replace equipment.
