Gas flow controller Xiao Bian tell you electromagnetic flowmeter replacement installation precautions

Electromagnetic flowmeter is a new type of flow measuring instrument developed rapidly with the development of electronic technology in the 50s and 60s of the 20th century. An electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow of a conductive fluid based on the electromotive force induced by the conductive fluid when an external magnetic field is applied.
Today, the gas flow controller Xiaobian talks about the matters that need to be paid attention to when replacing and installing the electromagnetic flowmeter.
1. Medium: The medium is the transmission of fluctuating energy, which requires the quasi-elastic collision of certain material elementary particles. The composition, shape, density, and motion state of this material determine the direction and speed of wave energy transfer. This material, which plays a decisive role in the propagation of waves, is called this wave medium. Including media type, temperature, pressure, flow range;
Second, as far as possible to avoid ferromagnetic objects and equipment with a strong electromagnetic field, so as not to affect the magnetic field sensors and flow signals.
Third, the electromagnetic flowmeter electrode corrosion resistance requirements are extremely high, does not allow corrosion, but very low corrosion in the practical application of engineering still exists. Therefore, when it is used in important places, it is necessary to conduct corrosive tests on site.
Fourth, the distance between the straight pipeline. Choose a convenient place for maintenance and activities. The flowmeter should be installed at the rear of the pump and must not be installed on the suction side. The valve should be installed on the downstream side of the flow.
The above are the matters needing attention for the replacement and installation of electromagnetic flowmeters. I hope that I can help you.
