● Before installation, check the pipelines in the cleansing system thoroughly and remove silk, hemp, sand ,gravel and any other masses to avoid any flow hindrance.
● The heat meter should be installed in horizontal level, with the display window facing upward.
● The water flow direction should be consistent with the arrow on the flow meter;
● The diameter of the front and the back pipes should fit the flow meter
● 10DN straight pipeline and 5DN straight line should be saved (DN is what we call the diameter of the heat meter)
● Must use the gasket and connecting pipeline specially designed and manufactured by our company.
● The sewage filter and the valve should be fixed at both ends of the flow meter for the convenience of filth removing, maintaining and replacing.
● After the installation ,seal between the connecting bolt of the capsule and the heat meter, between the temperature measuring ball valve and the platinum resistor.
● Inlet and the outlet pipe optional installation, easy construction (need to specify when ordering).
The RC type ultrasonic heat meter is a measuring instrument used to measure and display the heat (cold) in the heat exchange circuit in the heat exchange circuit. The measured unit KWh shows the heat (cold), which consists of flow sensor, temperature sensor, calculator three parts.
