What is the difference between electromagnetic flowmeter and magnetoelectric flowmeter?

The magnetoelectric flowmeter is called the magnetoelectric intelligent flow (unit: cubic meters per second). Vortex Flowmeter This product features advanced circuit, low power consumption, wide range ratio, simple structure, low resistance loss, ruggedness, wide application, long service life, stable operation and easy installation and debugging. It is mainly used for flow measurement of industrial pipeline medium fluids, such as gases, liquids, vapors and other media. The advantage is that it combines the advantages of vortex flow (also known as: Foucault current) meter and electromagnetic flowmeter, and is one of the most economical intelligent flow meters. Adopting advanced single-chip technology and new micro-power technology, it has the advantages of simple structure, no moving parts, small pressure loss, high measurement accuracy, wide range ratio, no zero drift, easy installation and maintenance, etc. It can measure conductive liquids including) The volume flow rate of strong corrosive liquids such as acid, alkali and salt, and pulp, mud, waste water and solid-liquid two-phase suspensions. The product is generally used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries and environmental protection, municipal management (guǎnlǐ), water conservancy construction and other fields.

Electromagnetic Flowmeter

The electromagnetic flowmeter is equipped with two symmetrical symmetrical coils on both sides of the flow tube of the flowmeter according to Faraday's electromagnetic induction law. The magnetic field conductor medium (determining substance) passes through the magnetic field. There are two more symmetric electrodes that generate the induced electromotive force to collect the flow rate of the induced electromotive force. In addition to measuring the volume flow of general conductive liquids, the sewage flow meter can also be used to measure the volumetric flow rate of strong corrosive liquids such as strong acid and alkali, and uniform liquid-solid two-phase suspension liquids such as mud, slurry and pulp. Widely used in petroleum, chemical, metallurgy, textile, paper, environmental protection, food and other industrial sectors and municipal management, water conservancy construction, river dredging and other fields of flow measurement. The electromagnetic flowmeter acts to produce a uniform DC or AC magnetic field. The DC magnetic circuit is realized by a permanent magnet, which has the advantages of simple structure and less interference by the alternating magnetic field, but it is easy to polarize the electrolyte liquid in the measuring duct, so that the positive electrode is surrounded by negative ions, and the negative electrode is positive ion Surrounding, that is, the polarization phenomenon of the electrode, and causing an increase in internal resistance between the two electrodes, thus seriously affecting the normal operation of the meter. The Electrocurrent meter is made by combining the characteristics of a vortex flowmeter and an electromagnetic flowmeter. It places a permanent magnet above the flowmeter and a sounding body at the inlet end of the fluid. The conductor medium generates a vortex through the sounding body, and the magnetic sensation line is divided by the vortex to generate an induced electromotive force and the electrode collects the induced electromotive force.

The amount of magnetic current (unit: cubic meters per second) is more troublesome to manufacture. Therefore, the price of the magnetoelectric flowmeter is relatively expensive. In addition, the magnetoelectric flowmeter has a horizontal installation and the angle is required to install it before and after the tube is broken. Not strict.
