What are the common fault symptoms of electromagnetic flowmeters? What factors affect measurement accuracy? How to properly diagnose and resolve faults? The induced voltage signal of the electromagnetic flowmeter sensor is linearly related to the average flow velocity, thus ensuring high measurement accuracy. There are no flow obstructing elements inside the pipeline, so there is no additional pressure loss ； Although electromagnetic flowmeters have good reliability and generally do not get damaged, due to their operating principle, the sensor electrodes are in constant contact with the liquid; over time, the surface of these electrodes is prone to contamination. Therefore, for electromagnetic flowmeters, whenever the customer has the means to do so, it is recommended to remove them and clean the electrodes every one to one and a half years in order to maintain the measurement accuracy of the entire flowmeter. Faults in electromagnetic flowmeters are primarily caused by damage to their components, while faults resulting from external factors are mainly due to issues such as the pipeline system and installation not meeting requirements, interference from the operating environment on the meter, and interference from the fluid being measured on the flowmeter’s measurement process. Among the common problems of electromagnetic flowmeters, those that occur during the commissioning phase are usually caused by installation issues or improper selection, while the problems that arise during normal operation are generally due to changes in operating conditions or the emergence of new interference sources. Therefore, problems that occur during normal operation can generally be attributed to the instrument’s resistance to interference.
