| Permissible installation orientation | The sensor can be installed upright to horizontal. The sensor may not be installed in a hanging position. |
| Installation in return | Installation in the return is recommended. |
| Dimensioning | The thermal energy meter is dimensioned to the nominal flow (qp). The flow rate may increase to the highest flow (qs) for a short time (<1h/day). |
| Inlet section | There are no requirements for straight inlet sections prior to the flow sensor. Product has been tested to and fulfills the requirements of EN1434-4:2022 |
| Water quality requirements | The water quality requirements specified in VDI 2035 must be adhered to. |
| Servicing | Thermal energy meter are maintenance-free. Before any service work on the thermal energy meter is carried out, it is essential to isolate the thermal energy meter from the power supply (by unplugging the electrical cables if necessary). Any pumps in the part of the piping system concerned must also be switched off and the appropriate slide valves closed (allow all components to cool down first if necessary and always reduce the system pressure to ambient pressure level). The system must not be returned to service until the thermal energy meter has been correctly reassembled in accordance with the instructions and the pipeline has been refilled by professionally trained personnel. |
| Flow direction | The direction of flow, specified by an arrow on the housing, is to be complied with, since otherwise the flow rate will be measured incorrectly. |
| Avoiding cavitation | To avoid cavitation, the system pressure at the outlet of the thermal energy meter must be a minimum of 14.5 psi (1.0 bar) at qs (highest flow) and temperatures up to 195 deg F (90 deg C). At a temperature of 250 deg F (120 deg C) the system pressure at the outlet of the thermal energy meter must be at least 36.3 psi (2.5 bar). |
| Cleaning of pipes | Before installing the thermal energy meter, the circuit must be thoroughly rinsed to remove impurities. |
