    The meter can be mounted horizontally or vertically, ensuring that the display window data is easy to read.

    (4) The direction of water flow should be consistent with the arrow on the flow meter, and the flow direction of water flow must be upward when installed vertically.

    (5) Before and after the diameter of the pipe to be consistent with the diameter of the flowmeter, and the front of the inlet straight pipe should not be less than 10 times the pipe diameter, the outlet pipe at the front end should not be less than 5 times the pipe diameter.

    (6) A dirt filter should be installed at the inlet end of the heat meter, and shutoff valves should be provided at both ends to facilitate the removal of dirt and maintenance and replacement.

    (7) The heat meter can be installed on the inlet or return pipe (pre-selected) according to the actual situation. It is recommended to install the inlet pipe.

    (8) It is recommended to configure a dedicated hot meter box for management.

    (9) When the installation space of the heat meter is limited and the environment is poor, we recommend using a split meter.

    (10) The installation process should be carried out gently to prevent damage to the instrument.

    (11) After installation, seals shall be made between the connection nut and the heat meter of the inlet and outlet of the heat meter and between the temperature measuring ball valve and the temperature sensor.

    2. Temperature sensor installation

    When the heat meter is installed in the water inlet pipe: The temperature sensor with red label should be installed on the temperature measuring hole of the heat meter body, and the temperature sensor with blue label should be installed on the temperature measuring seat dedicated to the return pipe.

    When the heat meter is installed in the return pipe: The temperature sensor with the red tag should be installed on the dedicated temperature measuring seat for the inlet pipe. The temperature sensor with the blue tag should be installed on the temperature measuring hole of the heat meter body.

    Temperature sensor wires must not be arbitrarily increased or decreased.
