Overview

The definition of electromagnetic flowmeter sensor: It can sense the measured data and convert it into usable signal devices or equipment by installing certain rules. It is usually composed of sensitive elements and conversion elements. Sensors are irreplaceable in the effectiveness of electromagnetic flowmeters. Its effect is not only in detecting the size of the flow rate, but also in the conversion of its signal. Intense sensation can cause damage to the electromagnetic flowmeter sensor. Causing the sensor to malfunction, resulting in various situations such as no display of the meter head, no flow rate displayed on the meter head, or unstable flow rate. When the electromagnetic flowmeter presents a violent explosion or sensation on site, the seismic source is close to the electromagnetic flowmeter, and the explosion causes intense vibration. When the vibration is too large, it will exceed the capacity of the electromagnetic flowmeter itself. The electromagnetic flowmeter itself has an excitation coil, and the magnetic field generated by the excitation coil is the measurement condition of the entire electromagnetic flowmeter. When the impact force caused by its shock is too large, it will cause the excitation coil to deform and crack. The inability to generate a working magnetic field or abnormal working magnetic field will affect the measurement accuracy of the electromagnetic flowmeter, and some electromagnetic flowmeters may even be unusable. Various situations such as displacement, deformation, cracking, etc. may occur due to the internal components of the electromagnetic flowmeter. The internal components of the electromagnetic flowmeter cannot be restored by themselves, making it impossible for each component to perform its intended function, and also resulting in the malfunction of the electromagnetic flowmeter. Possible causes and solutions for electromagnetic flowmeter display alarms. Facing the diversity on site, please carefully refer to the instruction manual.

electromagnetismflowmeterPossible reasons for displaying alarms:Corresponding handling measures:

1Excitation alarm1Check the resistance of the excitation coilFind the open circuit (short circuit) point, replace the converter with a normal resistance value

IIAir traffic control alarm (air traffic control threshold)2Check if there is any medium in the pipeline or check the conductivity of the medium

IIITraffic status alarm3Check if the flow rate meets the requirements

The main reasons for the excitation alarm of the electromagnetic flowmeter are the above-mentioned ones. I hope it can help everyone. If you want to learn more knowledge, please pay more attention to Huayun Instrument!
