The following tasks are necessary for installing the energy meter:
1. Install the flow sensor, see Section 6.1.1
2. Install the calculator, see Section 6.1.2
3. Connect the temperature sensor, see Section 6.1.3
4. Install the temperature sensor, see Section 6.1.4
6.1.1 Installing the flow sensor
NOTE
Thoroughly flush out the system before installing the flow sensor. It is recommended
that a strainer be fitted before the flow sensor or at another suitable position in the
heating or cooling circuit. The straight calming length of inlet pipe to the flow sensor
and the straight calming length of outlet pipe at the output of the meter may be 0 DN,
but an inlet pipe length of 10 DN is recommended before the meter for heating
systems without temperature mixing or with temperature stratification.
The meter can be installed in either horizontal (Fig. S, item 2) or vertical pipes
(Fig. S, item 1).
We also urgently recommend installing the flow sensor in a tilted position (45°) in
order to remove possible air bubbles from the circuit.

Installation in this position is not allowed or not approved
Select the installation position to suit the design of the meter. Check the information in the display
loop 3 to determine whether the meter is intended for installation in the hot or cold line of the
system.
Select the installation position to avoid air bubbles collecting in the meter (Fig. S, item 1 and 2).
