Electromagnetic flow meter

magneticvolumefor liquids

Construction of Electromagnetic Flow Meter Electronic Part consists of head type Flow Indicator which contains Microprocessor Controller chip mounted on the electronic circuit. It has the LCD display, Which shows the Current flow rate & Total commutative flow. Also, has a transmission feature of 4-20 mA output & RS 485 Communication with High & Low Flow Alarm. To operate it requires an external power supply of 24 VDC or 230 VAC. The mechanical part consists of Flow Tube, Lining such as of PTFE Or Neoprene, Electrode, Magnetic Coil, Flange connection. Flow Tube Material is non-wetted part and should be of the nonmagnetic material such as SS 304 Or SS 316. Selection of Lining Material must be according to temperature, corrosive property & compatibility of the measured fluid. Neoprene can resist general weak acid, alkaline corrosion and can withstand temperature unto 80˚C, but it has wear resistance. As PTFE (Teflon) has low wear resistance and have good compatibility to almost all strong acid, chemical, alkaline corrosion, ETP Water, Waste Slurry. And can withstand temperature up to 180˚C. Selection of Electrode Material must be according to corrosiveness of measured fluid Silent Features Total / accumulated total / flow rate Auto empty-full pipe check Ultrafast response time 4-20mA and pulse output high and low alarm (2-relay output) Modbus (RS485) Can handle slurries and heavy particulates Good accuracy (0.5 to 1%) Can respond well to fast changing flows
