Installation notes for sensor adapter set
A mounting set is included for meters with 5.2 × 45 mm temperature sensor.
With this you can fit the temperature sensor directly immersed into an insert or
a ball valve for example.
1.
Install with O-ring at the point of installation with the fit-up aid/pen provided.
2.
Place both halves of the plastic bolting round the 3 notches of the tempera-
ture sensor.
3.
Press the bolting together and screw the bolting hand tight into the point of
installation until it comes to a stop (tightening torque 3 ... 5 Nm).

Asymmetric mounting (temperature sensor)
The meter can be mounted asymmetric, too. This means one temperature
sensor is directly immersed in the volume measuring tube, whereas the other
temperature sensor is mounted in a protection pocket. For the lower value of
the temperature difference is then 5 K valid at the respective lower flow limit
qi. For this kind of installation the mentioned protection pockets must be used.
Furthermore the national regulations of the respective country have to be ob-
servered.

4.1 Installation for cooling metering and combined heat/cooling meters
Fit the electronic unit separate to the volume measurement unit, e.g. on the
wall for water temperatures below 10° C. Make a loop downwards in order to
prevent condensation running along the connected lines into the electronic
unit. Install the temperature sensors into the pipe from below.
Note:
Wall adapter plates are available as an accessory.
