What are the general types of electromagnetic flowmeter
Mar 09, 2018
The task of electromagnetic flowmeter is to measure the volume flow of conductive liquid, including water, food, beverage, chemicals, mud, pulp and pulp with magnetic particles. There are three models of these precision electromagnetic flowmeters.
Whether it is a standard flowmeter with rectangular wave pulse excitation technology, a High-Performance AC pulse excitation flowmeter, or a battery powered electromagnetic water meter, an electromagnetic flowmeter from zhongruineng instrument production line can reduce the difficulty of flow management. Zrn-ldc electromagnetic flowmeter produced by zhongruineng instrument is a precision product trusted by users all over the world.

1. In metallurgy, papermaking, sewage treatment and other industries, electromagnetic flowmeter is generally separated and large-diameter flange connected; However, in biomedicine, chemical industry and other industries, many small-diameter and integrated clamping connection methods are used, and the specifications of electromagnetic flowmeter required in different fields are different.
2. In some explosion-proof occasions, the instrument is required to have good explosion-proof and flame-proof performance. In these occasions, the energy of exciting current is very large. Electromagnetic flowmeter can be divided into air tight type, diaphragm type and sand filled type. With the rapid development of science and technology, the power of exciting current has decreased a lot. Therefore, the most common flowmeter in explosion-proof occasions is safe spark type. It is composed of flow sensing part and conversion part, which is mainly used in dangerous areas.
3. In industries such as food hygiene and medicine, the sensor of electromagnetic flowmeter is required to be easily disassembled, which is also convenient for cleaning and steam sterilization on a regular basis. Therefore, in the health industry, the electromagnetic flowmeter should meet the sanitary specifications.
4. The instruments used in the channel are submersible type, which are mainly used in industrial drainage and sewers. They should carry out relevant drainage work with the help of hoist. At the same time, the sensor of the electromagnetic flowmeter shall be installed under the baffle of the open channel, and shall not be immersed under the water for a long time.
Of course, the classification of electromagnetic flowmeter is not only these types. In different industries, the use requirements of battery flowmeter are different. Just like the specifications of conveyor belt in logistics transmission, there are many types of electromagnetic flowmeter, which can meet the needs of different fields.
