Main functional characteristics

1.    Non magnetic flow meter without magnetic interference.
2.    High sensitivity, Perfect data storage, Long life of lithium battery.
3.    The controller can rotate freely, so as to observe the readings conveniently.
4.    Complete data display, Guarantee the accuracy of measurement.
5.    Small pressure loss, strong anti-theft ability.

Installation notes and Instructions:
1. Before installation, the pipes should be cleaned up firstly in case of pipes block which will influence normal working of heat meter. And we suggest that it will be better to install filter device in front of the heat meter.

2. Heat meter should be installed at the place of water outlet of the pipe, to avoid pollution, and make it easy for dismantling and check.

3. Heat meter should be installed horizontally (with the side of display upward), the direction of arrow should be the same with that of the water flow direction in the pipe.

4. The inlet temperature sensor (line with red label) should be installed on the joint of the water entrance, and the outlet temperature sensor (line with blue label) should be installed on the joint of the water exit.

5. Don’t use excessive force when connecting meter and pipe in order to avoid crushing sealed washer and cause water leaking.

6. Handle with care when delivery and avoid store the meters in strong magnetic field.
