JC-090 Electromagnetic Flow meter
Description Of Products
Electromagnetic flowmeter is a kind of inductional instrument designed by Faraday’s law of electromagnetic induction to measure flow of conductive media in the tube. It adopts the technology of insertion of single chip to realize digital excitation and employs CAN local fieldbus.
Electromagnetic flow meter can realize local indication and output electrical current signal of 4-20mA which can be used to record, adjust and control. Electromagnetic flow meters are widely used in industrial sectors such as chemical industry, environmental protection, metallurgy, pharmaceutical, paper making, water supply and removal etc.
Besides measuring flow of general conductive liquid electromagnetic flowmeter can measure flow of liquid-solid mixed fluid, high-viscosity fluid and salt, strong acid and strong alkali.
PERFORMANCES & FEATURES
● Simple structures, firm, no movable parts and long operation life
● No intercepting fluid parts, no pressure loss and fluid clogging
● No mechanical inertia, quick response and good stability, apply in automatic examination, adjustment and controlling
● Measuring accuracy not influenced by physical parameters such as style, temperature, viscosity, density and pressure.
● Employ Teflon or rubber liner and different combination of electrode material such as Hastelloy C, Hastelloy B, 316L,
● T itanium and adapt the need of different mediums.
● Supply many styles of flowmeters such as inline type and insertion type, etc.
● Adopt EEPROM memory to measure operation data, safe and reliable protection of memory.
● Integral type flowmeters and remote type flowmeters.
● LCD back light display with high clearness
