Negative Pressure Resistance Electromagnetic Flow Meter with LED Display for Sewage Treatment
Negative Pressure Resistance Electromagnetic Flow Meters With LED Display Used For Sewage Treatment Water
Electromagnetic Flow Meter is an 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.
- Simple structures, firm, no movable parts and long operation life (Guarantee in 1 years)
- No intercepting fluid parts, no pressure loss and fluid clogging
- No mechanical inertia, quick response and good stability, application in automatic examination, adjustment & controlling
- Measuring accuracy not influenced by physical parameters such as style, temperature, viscosity, density and pressure
- 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
- High pressure sensor with PFA liner is resistant to high pressure and negative pressure, and available to chemistry and corrosive solution
- It is applicable not only to general process, but also in tough applications such as mining, papermaking, pastry, etc.
