1. product introduction
Ultrasonic flow module/RTU is widely used in all kinds of liquid for long time measurement, neither need broken tube nor block installation. The main unit uses guide installation, and the sensor was installed in the measurement pipelines. The main unit and sensor connected by the ultrasonic flow meter’s special power cable, not only can complete the flow measurement, but also complete the measurement of the quantity of the heat. This series are widely used to meausre the form a complete set of system integration, water resources, energy saving, water supply and drainage, heating network monitoring projects such as flow rate, heat metering.
2. the features
High accuracy: accuracy can reached to 1 %.
Wide measuring range: Several types transducer for selection, pipe size from DN15mm to DN6000mm
High reliability: Low voltage, pulse transmission circuit, high measurement accuracy, Improve the service life and reliability.
Strong anti-interference ability: Adopt double balanced differential signal transmitting and receiving circuit to resist inverter, television tower, high tension line
interference effectively.
Powerful Functions: Current output: 4-20mA, one channel, can be used for flow/heat transmitter;
OCT output: two channels, can be used for flow /heat switch;
Current input: 4-20mA, three channels, can be used for data collector;
Tri-wire resistance signal input (PT100): two channels, can be used for calorimeter.
Far transmission distance: Connecting module and secondary meter through RS-485 interface, transmission distance up to 1000m.
Support the heat measurement: measuring the heat through connect with the temperature sensor.
