1. General information
Read this guide before installing the energy meter. If the meter is installed
incorrectly, Kamstrup’s guarantee obligations will no longer apply.
Please note that the following installation conditions must be obeyed:
- Pressure stage ULTRAFLOW®:
PN16/PN25/PN40, see marking. Marking of flow
part does not cover included accessories
- Pressure stage Kamstrup
sensor set type DS:
PN16
- Pressure stage Kamstrup
stainless steel pockets:
PN25/PN40 - depending on type
If the medium temperature exceeds 90°C we recommend to use flange meters and
to mount MULTICAL® 601 on the wall.
2. Mounting of temperature sensors
Temperature sensors used to measure flow and return temperatures make
up a matched pair of sensors and must never be separated.
Usually, MULTICAL® 601 is supplied with mounted temperature sensors. According
to EN 1434 or OIML R75 the cable length must not be changed. Replacement of
sensors, if required, must always be made in pairs.
One sensor is marked with a red sign, and must be installed in the flow pipe.
The other sensor is marked with a blue sign, and must be installed in the return
pipe (see paragraph 8 on page 11).
2.1 Pocket sensor pair
Preferably, sensor pockets must be mounted in tee-pieces or in 45°C lateral
Y-pieces. The tip of the sensor pocket must be placed pointing towards the
flow direction and in the middle of the water flow.
Temperature sensors should be inserted to the bottom of the pockets. If a quick
response time is required, “non-hardening” heat conducting paste can be used.
Push the plastic sleeve on the sensor cable into the sensor pocket and secure the
cable with the supplied M4 sealing screw. Fasten the screw with your fingers only.
Seal the pockets using seal and sealing wire.
