Note: In the following text, the term meter WSM5.. re-
fers to both the heat meter WSM5.. and the cold meter
WSB5.., unless they are otherwise differentiated.
1. General
1.1 Use
The WSM5.. meter measures the heat or cold consumed in
heating plants.
The meter consists of a high-tech plastic volume-measuring
unit, two temperature sensors connected in a fixed position and
an electronic unit which calculates the energy consumption
from the volume and temperature difference. The meter com-
bines modern microcomputer technology with innovative ultra-
sonic measuring technology for which no mechanically moving
parts are necessary.
This technology is thus wear free, robust and largely mainte-
nance free. High precision and long-term stability guarantee
precise and equitable cost accounts.
Note: The meter cannot be opened without damaging
the security seal.
1.2

General notes

The meter left the factory in a faultless condition where safety
is concerned. The manufacturer will provide additional tech-
nical support on request. Calibration-relevant security seals on
the meter must not be damaged or removed. Otherwise the
guarantee and calibration validity of the meter will lapse.

Keep the packaging so that you can transport the meter in
its original packaging following expiry of the calibration va-
lidity.

Lay all cables at a minimum distance of 500 mm to high
voltage and high frequency cables.

A relative humidity of < 93% at 25°C is permissible (without
condensation).

Avoid cavitation in the whole system due to overpressure
i.e. at least 1 bar at qp and approx. 2 bar at qs (applies for
approx. 80°C).

Safety Information

The meters may only be used in building service engi-
neering plants and only for the applications described.
The meter is designed in accordance with the guidelines
of the environment categories M1+E1 and must be fitted
in line with these regulations.
The local regulations (installation etc.) must be adhered
to.
Adhere to the operating conditions according to the dial
plate during use. Non-adherence can cause hazards
and the guarantee will become null and void.
Do not under any circumstances carrying out welding,
drilling or soldering work close to the meter.
The meter is only suitable for circulating water in heating
plants.
The meter is not suitable for drinking water.
Adhere to the AGFW requirements regarding circulating
water (FW510).

Recommendation: If you are installing several meters, the
same installation conditions must be consistent for all meters.
UH068 – 006a
Only trained staff may install and remove the meter.
Only fit or remove the meter when the appliance is free
of pressure.
Carry out a leak test with cold pressure following instal-
lation.
Guarantee and calibration validity will become null and
void if the calibration relevant security seal is broken.
Only clean the meter from outside with a soft, lightly
wetted cloth. Do not use any spirit or cleaning solvent.
As far as disposal is concerned, the WSM5.. is a waste
electronic appliance in the sense of European Directive
2002/96/EC (WEEE) and it must not be disposed of as
domestic waste. The relevant national, legal regulations
must be observed as the appliance must be disposed of
via the channels provided for this purpose. The local
and currently valid legislation must be observed.
You can return the lithium batteries to the manufacturer
for appropriate disposal following use. When shipping
please observe legal regulations, in particular, those
governing the labelling and packaging of hazardous
goods.
Do not open the batteries. Do not bring batteries into
contact with water or expose to temperatures above
80 °C.
The meter does not have any lightning protection. En-
sure lightning protection via the in-house installation.
Installation
Determine the place of installation in line with the inscrip-
tion on the meter.
Installation into
return-flow:
Observe the dimensions of the meter and check whether
there is sufficient space available.
Clean the appliance 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.
Note: Only use the rubber EPDM flat seals that are
supplied.
The meter must not be exposed to any of the stress or
forces caused by pipes or shaped pieces. 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 connecting brackets for example.
Fit the sensors in the same circuit as the meter.
Seal the temperature sensor and the fittings to protect
against manipulation.
If you install the meter as a cold meter, observe the appro-
priate notes.
