Fig. 3: Fig. 7: Integration for circuits with mixing; placement of the temperature sensor

Fig. 4: Fig. 8: Integration for circuit with e.g. throttling circuit (flow sensor in the direction of flow prior to

control valve / differential pressure controller)

Please note the following torques for tightening screws and bolts on the meter:

● Screws on lock to the device cover (Fig. 1, No. 4): At least 1 Nm

● All other screws: Hand tighten, ca. 0.5 Nm

Required position for the cooling energy meter

To avoid the formation of condensation on cooling energy or combined heat/cooling energy

meters, make sure the cover on the measuring tube points to the side or downward. Install

the protection pockets so that the temperature sensor is horizontal or vertical, pointing down.

Forms a loop down using the connected wires. Mount the processor unit away from the flow

measuring section (e.g. on the wall). Make sure that condensation cannot run along the

connected lines, entering the processor unit (forming a loop downward).

Permissible mounting position when metering cooling energy:
