MTF Metal Tube Variable Area Flowmeter

Summary
MTF metal tube variable area flowmeter is one of the intelligent instruments that are developed and manufactured
in DDTOP. It integrates analog circuit, digital circuit and microprocessor. It converts the analog voltage signals
correspondingly to the flowrate signals into 4-20mA two-wire system current output signals on which HART
communication protocol may be superimposed on it. 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 the functions of 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.
