Description of the use of electromagnetic flowmeter

The electromagnetic flowmeter is a flow meter with high precision, high reliability and long service life. The fluid to be tested should not contain more ferromagnetic substances or bubbles. The pressure level, lining material, electrode material and instrument structure should be selected according to the temperature, pressure, corrosion and wear properties of the fluid to be tested. As a professional manufacturer of electromagnetic flowmeters, because of its reliable quality, the products are widely used in various industries across the country.

In the industry, the flow meter is a flow measuring instrument, and the electromagnetic flow meter is also a kind of flow meter. Generally, the type of the electromagnetic flow meter used in different occasions is also different.

1. In the food hygiene, medicine and other industries, the sensor of the electromagnetic flowmeter is required to be easily disassembled, so that it is also convenient to clean, and it is convenient to steam sterilize it regularly. Therefore, in the health industry, electromagnetic flowmeters must comply with hygienic specifications.

2. In the metallurgy, papermaking, sewage treatment and other industries, the electromagnetic flowmeter is generally a separate type, large-diameter flanged type; in the biomedical, chemical and other industries, the use of small-diameter, integrated clip-on connection There are many more, and the specifications of electromagnetic flowmeters required in different fields are different.

3. In some special places, such as some explosion-proof occasions, the instrument needs to have good explosion-proof and flameproof performance. In these occasions, the energy of the excitation current is very large, and the electromagnetic flowmeter can be classified into airtight type. , diaphragm type and sand filling type. With the rapid development of technology, the power of the excitation current has dropped a lot. Therefore, the most common flowmeter in the explosion-proof situation is the safety spark type. It is composed of the sensing part and the conversion part of the flow, mainly used in Within the danger zone.

4. The instruments used in the channel are submersible, mainly used in industrial drainage and sewers, and they rely on the power of the hoist to perform related drainage work. At the same time, the sensor of the electromagnetic flowmeter should be installed under the baffle of the open channel, and should be immersed under the water for a long time.

The classification of electromagnetic flowmeters will be different according to the different classifications. Generally, the conventional ones will be classified into three categories: integrated electromagnetic flowmeters, split electromagnetic flowmeters, plug-in electromagnetic flowmeters, and so on. Different types of flowmeters for different occasions, the correct selection of electromagnetic flowmeters is a powerful boost in work efficiency.
