What are the factors affecting the split electromagnetic flowmeter?

Split-type electromagnetic flow meters use the latest technology in the world. The use of constant-current low-frequency rectangular wave or dual-frequency rectangular wave excitation not only has the advantages of rectangular-wave magnetic field, but also overcomes the shortcomings of the sine-wave magnetic field; it can also eliminate power supply voltage fluctuations, power supply frequency changes and changes in the impedance of the excitation coil Errors; excellent zero stability and immunity to fluid noise interference. Therefore, it has the characteristics of high stability and high reliability.

The common debug-time failures of the split electromagnetic flowmeter are generally caused by improper installation, environmental disturbances, and fluid characteristics.

1. Generally, electromagnetic flow sensors, faults caused by incorrect orientation of the device, are often located at the highest point of the pipe system where gas can easily accumulate, and can be discharged. The fluid is directly discharged into the atmosphere and constitutes a non-full pipe within the measuring pipe.

2. Debugging fault debugging debugging expects that the fault is generally present during debugging of the external device. Once it is cleaned, it will not be presented again under the same conditions in the future.

3. In the fluid to be measured, the fluid does not normally affect the normal operation of the electromagnetic flowmeter. However, as the size of the bubble increases, if the bubbles are large enough to cover all the external surfaces of the electrode, the bubble will flow intermittently as the bubble flows through the electrode. The road will make the output signal appear more shaken.

4. The environment is generally mainly disturbed by stray currents in the pipeline, disturbed by strong electromagnetic waves in the space, and disturbed by the magnetic field of a large-sized motor. The stray current disturbance of the pipeline generally adopts excellent independent grounding maintenance to obtain satisfactory results. The space electromagnetic wave interference is generally introduced through the signal cable, and the single-layer or multi-layer shielding is generally used for maintenance.
