Faults and Countermeasures of the Electromagnetic Flowmeter

In industry, the electromagnetic waste water flow meter is one of the instruments commonly used to measure the flow of conductive liquids. The magnetic flow meter can measure a variety of corrosive media and slurry with suspended particles.

It should select the installation position of the mag flow meter according to the need. The mag flow meter sensor can be installed inclined or vertically. Regardless of the form to install the magnetic waste water flow meter, it is necessary to ensure that the axis of the two electrodes is approximately in the same horizontal direction.

When installing the mag flow meter, it should make sure the sensor of the magnetic water flow meter installed in the measuring pipe filled with the measured medium. The sensor of the magnetic flow meter is not particularly sensitive to vibration. If installing the magnetic flow meter in the place of strong vibration, it is necessary to install the sensor on both sides of the pipe to install support.

Faults that occur during the operation of the mag flow meter refer to faults that occur after the waste water flow meter has been debugged and operated normally for a while. Common mag flow meter failures during operation are generally caused by factors such as failure of the adhesive layer on the inner wall of the sensor of the mag flow meter, lightning strikes, changes in operating environmental conditions, and changes in system zero position.

Magnetic water flow meters often measure the flow measurement of industrial water. After the magnetic flow meter has been running for some time, the adhesion layer on the inner wall of the sensor will be scaled, which will affect the operation of the electromagnetic waste water flow meter. It is necessary to clean it in time to keep the electromagnetic waste water flow meter measuring pipe clean and smooth.

In the electromagnetic flow meter operation for some time, the sensor wall attached layer will have scaling, which affects the mag flow meter work. Be sure to clear the scale, to keep the magnetic water flow meter measurement pipeline clean and smooth.

In the instrumentation line, lightning strikes make it easy to sense high voltage and larger intensity current, thus causing mag flow meter in the operation process by lightning strike damage. Lightning into the magnetic water flow meter is the main way for the power line, excitation coil, and flow signal line. Lightning through the conductor current increases instantly, beyond the electromagnetic flow meter current carrying degree, thus causing electromagnetic flow meter failure.

When the debugging environment of the mag flow meter is interfered with by pipeline current dissipation or strong electromagnetic waves in space, the measurement results will be seriously affected. If the above situation occurs, timely measures need to be taken to reduce the degree of interference.
