Product Description

Ultrasonic heat meter

Ultrasonic heat meter is an instrument used to measure and display the heat energy released or absorbed by water flowing through the heat exchange system.When water flows through the Heat meter installed in the heat exchange system, calculate and display the heat energy released or absorbed by the system through a calculator according to the flow rate given by the flow sensor, the inlet and return water temperature signals given by the paired temperature sensor, and the time of water flow.

 INSTALLATION REQUIREMENTS

1,Heat meter must be installed in dry accessible place. 2,Using professional installation tools to install the heat meter. 2,The heat meter both can be installed in Inflow pipe or Return flow pipe (factory default installed in the inflow pipe, if need to install on the return pipe, must be clearly indication before the factory during the production). When installation, should pay attention to the flow direction of medium is as the same as the arrow on the heat meter pipe body.Special note: no matter the heat meter installed on inflow pipe or return flow pipe, the temperature sensor should be properly connected ( red label for inflow pipe, blue label for return pipe).

4,When install the heat meter, front straight pipe length should not be less than 5 times of the pipe diameter, back straight pipe length should not be less than 2 times of the pipe diameter.

5,Pipe should be kept horizontal as much as possible, and pipeline's sectional area should be not big changes. 7,In order to ensure the meter accuracy, the cable of temperature sensor shall not be cut short or make longer. 7,When the meter is vertical installation in the same position in each floor, between each meter should have partition wall, prevent pipeline leaking or other things falling to damage the meter. 8,Heat meter horizontal installation as the best location, which is beneficial to the meter is normal working . 9,Suggest the meter installed in special box, and with lock, in order to avoid damage. 10,Replace the battery must by professional staff. 11,Wiring Guidelines: M-BUS wiring: black, white (non polarity)RS-485 wiring: red wire to VCC (24VDC+), blue wire to GND (24VDC -), brown wire to A, gray wire to B.
