Displacer Liquid (Interface) Level Transmitter

Not only can the transmitter indicate the liquid level in a vessel directly on field, but also it can output 4~20mA analogue signals and digital signals being in conformity with HART PROTOCAL and being superimposed on it. For ZTD-GZ type transmitter, it can be used to constitute production process measurement and monitoring management systems to realize remote configuration, monitoring, maintenance and calibration, etc functions since it adopts HART bus technique.

The transmitters characterize themselves with high precision, low drift, and strong anti-interference ability. So, they can be used extensively for measuring liquid levels of dirty, inflammable, explosive and corrosive fluids, etc. and transferring the levels signals into analogue signals and transmit them out.

They are ideal level measurement instruments for production process control in petroleum, chemical, metallurgy, electrical power and light industrial products industries. The transmitters figure themselves with their fashionable shell structures, elegant appearances and high safety reliability because of separated chambers.
