Product Description


KDRL Type Ultrasonic heat meter is developed on the basis of ultrasonic water flow meter and utilizes ultrasonic transit-time principle.

In the heat-supply system, the hot water supply heat(cool) through releasing(absorbing in cooling syetem ) heat to users, in certain period of time, the heat is proportional to the hot water differential temperature of the inlet and outlet, and as well as the hot water volume through the pipe.

The hot water amount flowing through the flow sensor is transported to the calculaor, the differencial temperature of the inlet and outlet of the pipe is also transported to the calculator by the paired termperature sensor installed on the pipe, the calculator can calculate the energy consumption through time integration according to the hot water volume and temperature difference flowing through the pipe.

Our ultrasonic heat meter support RS485 teletransmission or M-BUS output for heat meter network management to make wireless reading. And the digital display part can be taken down from the sensor to read conveniently, no moving parts,no pressure loss, small and light with nice apperance are also the advantage of our Ultrasonic Heat Meter.
