Installation
To install the meter proceed as follows:
•
Determine the place of installation in line with the inscription on the meter.
Note:
For a
heating 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 two slide valves so that the
arrow on the housing and the flow direction match. Also observe the instal-
lation situations and the following examples of installation.
Note:
Only use the rubber EPDM flat seals that are supplied.
•
The meter must not be exposed to tensions or forces caused by pipes or fit-
tings. If this cannot be permanently guaranteed, it is necessary to improve
the point of installation or fix the lines in position, by means of suitable con-
necting brackets for example.
•
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.
Recommendation:
If you are installing several meters, the same installation
conditions must be consistent for all meters.
Installation Notes
Inlet or outlet sections are not necessary. If you install the meter in the com-
mon return of two circuits, determine a place of installation with a minimum
distance 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:
Protect the meter against damage through impacts or vibra-
tions at the place of installation.
