Electronic Unit - Siemens WSx6 Serie Manual De Manejo Y De Montaje


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 direc-
tion match. Also observe the installation situations and the
following examples of installation.

Fit the temperature sensors in the same circuit as the me-
ter. Please observe admixtures.

Seal the temperature sensor and the fittings to protect
against manipulation.

If you install the meter for cooling metering, follow the ap-
propriate notes.
Recommendation: If you are installing several meters, the
same installation conditions must be consistent for all meters.
Installation notes
Note: When installing the meter, the locally applicable
installation regulations for meters must be observed.
Inlet or outlet sections are not necessary. If you install the
meter in the common 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 mixing of the different
water temperatures. You can install the temperature sensors in
T-pieces, ball valves, directly immersed or in pockets depend-
ing 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 vibrations at the place of installation.
Note: Ensure the electronic unit is protected against any
ingress of water.
Recommendation: Do not install the meter on the intake side
of a pump. Maintain a minimum distance of 10 x DN on the
outlet side.
Examples of installation (directly immersed sensor)
You can install the meter in any position e.g. vertically or hori-
zontally. In order to avoid accumulation of air and disruption in
operation, fit the meter in a vertical installation position and not
in the uppermost area of a pipeline.

This position is not permitted for cold
meters and in cases where moisture can
enter the electronic unit due to conden-
sation (e.g. during an interruption in the
summer).

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

3.1 Installation of cooling meters and combined
heat/cooling meters
Observe the following installation instructions to avoid conden-
sation water.

Mount the cooling meter so that the black cover on the
measuring section points sidewards or downwards.

Mount the electronic unit separated from the volume meas-
uring unit e. g. on the wall.

Form a loop downwards with the connected cables.

Mount the protection pocket so that the temperature sensor
stands vertically downwards or horizontally.

Mount the temperature sensor horizontal or vertical in the
pipe from below.

Electronic unit

The ambient temperature of the electronic unit must not ex-
ceed 55 °C. Avoid direct sunlight.
Mount the electronic unit separated from the volume meas-
urement unit e. g. on the wall if the water temperatures are
below 10 °C and above 90 °C
