Electromagnetic flowmeter is a kind of induction meter which is made according to Faraday’s law of electromagnetic induction to measure the volume flow of conductive medium in the tube. In the 1970s and 1980s, the electromagnetic flow has made a great breakthrough in technology, making it a widely used kind of flowmeter, and the percentage of its usage in the flow meter is rising.
Overview of Application:
Electromagnetic flowmeter is widely used in the field of large diameter meters are more used in water supply and drainage engineering; Small and medium-sized caliber is often used in high requirements or difficult to measure occasions, such as iron and steel industry blast furnace cooling water control, paper industry measurement paper slurry and black liquid, chemical industry strong corrosion liquid, pulp of nonferrous metallurgy industry; Small caliber, small caliber is often used in the pharmaceutical industry, food industry, biochemistry and other places with health requirements.
Advantages:
1. Measurement channel is A smooth straight pipe, which will not block, and is suitable for measuring liquid-solid two-phase fluid containing solid particles, such as pulp, mud, sewage, etc.
2. Does not produce pressure loss caused by flow detection, and has good energy saving effect;
3. The measured volume flow rate is actually not significantly affected by changes in fluid density, viscosity, temperature, pressure and conductivity;
4. large flow range, wide caliber range;
5. Corrosive fluids may be used.
Disadvantages:
1. Can not measure very low conductivity of liquid, such as petroleum products, pure water, etc.;
2. cannot measure gases, vapors and liquids with large bubbles;
3. cannot be used at high temperatures.
