Description
Electromagnetic flow meter is a kind of induction 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 flow meter can measure flow of liquid-solid mixed fluid, high-viscosity fluid and salt, strong acid and strong alkali.
Features
1. Simple structures, firm, no movable parts and long operation life.(Guarantee in 1 years)
2. No intercepting fluid parts, no pressure loss and fluid clogging.
3. No mechanical inertia, quick response and good stability, application in automatic examination,adjustment & controlling.
4. Measuring accuracy not influenced by physical parameters such as style, temperature, viscosity,density and pressure.
5. Employ Teflon or rubber liner and different combination of electrode material such as Hastelloy C,Hastelloy B, 316L, and Titanium and adapt the need of different mediums.
6. Supply many styles of flow meters such as inline type and insertion type, etc.Adopt EEPROM memory to measure operation data, safe and reliable protection of memory.
7. Integral type flow meters and remote type flow meters.
8. LCD back light display with high clearness. (Option: LED back light display)
