Product Detailed

water flow meter-metal tube variable area flowmeter features high precision, low drift, strong capability of anti-interference

water flow meter-MTF metal tube variable area flowmeter

MTF intelligent metal tube float flowrate meter is developed and manufactured one of intelligent series instrument. It is one kind of a combined that integrates analog circuit, digital circuit and microprocessor. It converts fluid flow signal into corresponding analog voltage signal which then is changed into 4-20mA two wire system current output signal on which HART protocol communication is superimposed. The meter adopts HART bus intelligent transmitter. Because of HART bus technology, it features high precision, low drift, strong capability of anti-interference, etc. It can realize functions for remote configuration, monitoring, maintenance and calibration, etc. It can compose production procedural measurement, monitoring control system. The meter can be classified into basic type ( horizontal mounting type, vertical mounting type), jacket type, damping type. It shapes a beautiful appearance that shows the modern fashionable case design with operating chambers separated.
