Installation requirements
Prior to installing the flow sensor part, ULTRAFLOW
®
24, the installation ought to be flushed while a fitting
pie e is epla i g the ete . ‘e o e adhesi e afe s f o the ete s i let a d outlet a d ou t the
flow sensor with couplings. You must always use new gaskets in original quality.
The flow sensor part must be correctly placed according to the drawings overleaf. See paragraph 7.2
The flow direction is indicated by an arrow on each side of the flow part.
Mounting the flow part you must make sure that the threaded length of the couplings does not prevent
proper tightening of the sealing surface and that PN10 or couplings/gaskets are used (PN16
couplings/gaskets can be used).
Using strainer and/or anti-pollution check valve (only to be used in cold water meters) the enclosed thicker
PE gaskets must be used to avoid damaging strainer or anti-pollution check valve.
Whe ou ti g the se so s o e tio a les
, please make sure that condensation water cannot
penetrate the sensor.

Electrical installations
MULTICAL® 62 is available for both 24 VAC and 230 VAC mains supply. The mains connection consists
of a two-wire cable without safety ground.
Use a strong connection cable with an outer diameter of max. 7 mm and ensure correct cable relief
for the meter.
National regulations for electric installations must be observed, including e.g. the cable cross section
used i elatio to the i stallatio s fuse size sho
t circuit current). Max fuse 6 A.
Installation in Denmark is subject to an SIK announcement 27/09 from The Danish Safety Technology
