About The Classification Method Of Electromagnetic Flowmeter


Electromagnetic flowmeters are used very large in current industrial occasions such as chemical production. Generally, as long as it involves liquid measurement, the first consideration is the electromagnetic flowmeter. Because of its own measurement characteristics, the electromagnetic flowmeter has obvious advantages in the measurement process. The advantages of electromagnetic flowmeters are mainly manifested in high measurement accuracy, PTFE lining resistance to acid and alkali, corrosion resistance, high pressure resistance, integrated liquid crystal display on the meter head, integrated flow, instantaneous flow, velocity, no moving parts in the pipeline, no blockage, full digital processing , Strong anti-interference ability, there are two kinds of pipe split and plug-in type, which can measure the flow of liquid-solid two-phase flow, high-viscosity liquid flow and salt, strong acid, strong alkali and other corrosive liquids.

about the classification method of electromagnetic flowmeter

Universal type: In metallurgy, petrochemical, papermaking, printing and dyeing, textile, water supply, sewage treatment and other industries, split type medium and large diameter flange connection methods are generally used; small diameter and small diameter meters are commonly used in industries such as medicine, biology, and fine chemicals. , Electromagnetic flowmeters with integrated clamp connection or threaded connection are suitable for many places.

Explosion-proof type: Explosion-proof electromagnetic flowmeter is used in places with flammable atmosphere. Since most of the electromagnetic flowmeters have large current energy, they are usually designed as flameproof, sand-filled, encapsulated, and airtight. However, the excitation power of some electromagnetic flowmeters has been greatly reduced, and there is also an intrinsically safe type, which was previously called a safe spark type. The flow sensor part and the conversion part are conditionally integrated, and all are installed in the hazardous area.

Hygienic type: cheese, food, medicine, biochemistry and other industries require regular steam sterilization. The sensor should be easy to disassemble and clean. The connection part with the pipeline requires a hygienic specified structure for quick loading and unloading. The material in contact with the liquid should be non-toxic harmless. The sanitary electromagnetic flowmeter was developed to meet the above requirements.

Rain-drenching type: used in manholes installed under the ground, can withstand water intrusion for a short time, equivalent to enclosure protection class IP67 or NEMA6; there are also electromagnetic flowmeter products equivalent to protection class IP68, which can withstand long-term diving.

Submersible type: used to measure the water flow under the free surface of open channels or partially filled culverts, such as industrial drainage and sewage. The sensor is installed in the lower part of the open channel interception baffle and is immersed in water for a long time. It is used to install multiple shunt models with the same shape as the sensor at the time of large flow to expand the flow.
