Installation Notes

Examples of installation

To install the meter proceed as follows:

Determine the place of installation according to the mark on the meter.
Note: For a heat meter the mounting place of the flow sensor cold
side is equivalent to return. The mounting place of the flow sensor
hot side is equivalent to flow.
Note: For a cooling meter the mounting place of the flow sensor
hot side is equivalent to the return. The mounting place of the flow
sensor cold side is equivalent to flow.

Observe the dimensions of the meter and check whether there is sufficient
space available.

Rinse the system thoroughly before installing the meter.

Fit the meter vertically or horizontally between 2 slide valves so that the ar-
row on the housing and the flow direction match. Also observe the installa-
tion situations and the following examples of installation.

Fit the temperature sensors in the same circuit as the meter.

Seal the temperature sensor and the fittings to protect against manipula-
tion.

If you install the meter for cooling metering, follow the appropriate notes.
Inlet or outlet sections are not necessary. If you install the meter in the com-
mon return of two circuits, choose a place of installation with a minimum dis-
tance of 10 × DN from the T-piece. This distance ensures a good thorough
mixing of the different water temperatures. You can install the temperature
sensors in T-pieces, ball valves, directly immersed or in pockets depending on
the version. The temperature sensor ends must reach to at least the middle of
the pipe cross section.
Note: During installation it must be ensured that no water can
enter the electronic unit during operation.
