Electromagnetic Flow Meter
Reference Standard
Uni-Tech's Electromagnetic flow meter model U-MAG 20 is designed for flow measurement of conductive liquids with no moving parts and a PTFE lining. Electromagneticflow meter is suitable for measurement of flow of conductive liquids, which is based on Faraday's law of Electromagnetic induction, according to which a voltage is induced in electrically conducting body moving in a magnetic field & this voltage is directly proportional to the velocity. Standard outputs include analog, frequency, Rs485 or GSM/GPRS connectivity. Local-and remote-display models are available. They meet the most demanding requirements on high measurement precision, long-term stability and hygienic standard.
