Electromagnetic flowmeters are essential precision instruments for industrial fluid measurement, featuring high stability and accuracy. However, they often encounter operational faults due to improper installation, harsh field environments and insufficient daily maintenance, undermining measurement reliability.
Common typical faults cover zero output, unstable readings, measurement deviation and zero drift. Zero signal failure is mainly caused by unfilled pipelines, power faults or damaged electrodes. Unstable readings usually result from medium impurities, air bubbles and electromagnetic interference. Measurement errors arise from incorrect parameter settings, non-standard installation and pipeline scaling, while zero drift is related to electrode contamination and missing calibration. Most system alarms are triggered by circuit damage and configuration errors.
Standardized installation, regular electrode cleaning, parameter recalibration and routine inspection are critical to eliminating common faults and maintaining the long-term stable operation of electromagnetic flowmeters in industrial systems.
