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.
Installation 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.
