3. Kurulum
Attention: Installation should be performed by trained personnel. The thermal cycle system must be a mechanical forced circulation system, as natural heat circulation cannot satisfy the pressure loss requirements of the heat meter.
- The heat meter must be installed in a dry, accessible location.
- Use professional installation tools for proper installation.
- The heat meter can be installed in either the inflow pipe or the return flow pipe. By default, it is factory-installed for the inflow pipe. If installation on the return pipe is required, this must be specified before production.
- When installing, ensure the flow direction of the medium matches the arrow indicated on the heat meter's pipe body.
- Özel Not: Regardless of whether the heat meter is installed on the inflow or return flow pipe, the temperature sensor must be connected correctly. The red-labeled sensor is for the inflow pipe, and the blue-labeled sensor is for the return pipe.
Installation Position Guidelines:
- Correct Positions:
- M-1: Horizontal installation.
- M-2: Vertical installation.
- Yanlış Pozisyonlar:
- M-3: Easy to accumulate bubbles, affecting measurement accuracy.
- M-4: Although vertical installation, there is no back pressure behind the meter, which may cause the fluid to not be completely full of pipes, affecting measurement accuracy.
