The Ultrasonic Heat Meter is the meter that measures the flow volume and displays the heat energy released or absorbed by water flow when passing through the heat exchange system. It measures and captures the physical quantity - the flow volume of the heat carrier and the temperature of inletandoutletbytwokindsofsensors,anditcapturestheheatenergyvalue by the compensation of the density and the heat energy and the integral computation.

Installation Installation positions of all parts of the flow meter(inc.the parts of flow sensor, temperature sensor and calculator) should avoid being approached by sun light, flooding, freezing, chemicals and electromagnetic pollutions, and should facilitates dismounting and metering. Installation of ultrasonic heat meter
Before installation should thoroughly clean the system piping,and clear the sand and other debris, avoid water meterfailure;
Body level or vertical installation, Building water meter installation should be less than 0.8m from theground;
Water flow direction should be consistent with the direction of the arrow marked on the meterbody;
Before and after the pipe diameter to be consistent with the bodydiameter;
When installing the water meter, should be reserved length of DN*10 in front of the water meter. Or should be reserved the length of DN*8 behind the water meter. (DN is the diameter of the heatmeter);
After installation, the meter body should be connected to the nut and pipe; and should put the lead seal between the flow sensor and resistance. 2.Temperature sensorinstallation
The temperature sensor should be installed inthemeterbody temperature measuring hole, and put the leadseal;
The temperature sensor circuit can't to be changed. Temperature sensors with red labels should be installed on the inlet pipe and the temperature sensor with blue label should be installed on the returnpipe.
