Installation
Technical requirements
1. The installation shall be performed according to the water flow direction mark on the pipe runs, and vertical installation shall ensure that the water flows from top to bottom;
2. The valves shall be provided before and after the meter, and the accessibility shall be ensured for the maintenance;
3. The straight pipe runs shall be provided before and after the meter. For the length of straight pipe runs, refer to the “Installation method”;
4. Avoid direct sunshine and high frequency radiation sources such as motor inverter;
5. Heat meter can be installed on the water supply and return pipes, but red Pt resistance must be installed on the water supply pipes;
6. For the installation of heat meter, the location where it cannot be filled with the water shall be avoided;
