The role of flowmeter in industry

The role of the flowmeter, according to the different role of the flowmeter can be divided into rotor flowmeter, throttling flowmeter, fine seam flowmeter, volumetric flowmeter, electromagnetic flowmeter, ultrasonic flowmeter.According to the medium can be divided into liquid flowmeter and gas flowmeter.In addition, there are target flowmeters, positive displacement flowmeters, turbine flowmeters, differential pressure flowmeters, variable area flowmeters, vortex street flowmeters, coriolis mass flowmeters and so on.

In the industrial field, the measurement of fluid flow meter is collectively known as the flowmeter or flowmeter.It is one of the important instruments in industrial measurement.With the development of industry, the accuracy and range of flow measurement requirements are increasingly high, in order to adapt to a variety of USES, various types of flowmeters have come out, widely used in petroleum and natural gas, petrochemical, water treatment, food and beverage, pharmaceutical, energy, metallurgy, pulp and paper and building materials and other industries.

Magnetoelectric converters are generally magnetoresistive in China, which consists of magnetic steel and induction coil wound externally.When the fluid rotates the steering wheel, the magnetoresistance of the blade is small when the blade is directly under the magnetic steel, while the gap between the two blades is large when the steel is under the magnetic steel. The turbine is rotating and constantly changing the magnetic flux of the magnetic circuit, so that the changed induced potential in the coil can be fed into the amplifying and shaping circuit and become the pulse signal.
