3 Mounting of flow sensor

Prior to installation of the flow sensor, the system should be flushed and protection plugs/plastic
diaphragms removed from the flow sensor.
Correct position of the flow sensor appears either from the calculator's type label or from the
display where ( indicates the position in inlet, whereas ) indicates the position in outlet. The
flow direction is symbolised by an arrow on the flow sensor.

3.1 Mounting of couplings and short direct sensor in flow sensor

The flow sensor can be used in connection with
either PN16 or PN25 (see marking).
Any provided blind plug, extension and gland
can be used with both PN16 and PN25.
In connection with flow sensors with the
Gasket
nominal dimensions G¾Bx110 mm and
Moment ~4 Nm
G1Bx110 mm, it must be checked if the thread
run-out is sufficient.
Gasket
Couplings and gaskets are mounted as shown
in the figure. Make sure to position the gasket
correctly in the recess of the gland as shown in
the details excerpt in the figure.
Kamstrup flow sensors require neither straight inlet nor straight outlet to meet the Measuring
Instruments Directive (MID) 2014/32/EU, OIML R75:2002 and EN 1434:2015. A straight inlet section
will only be necessary in case of heavy flow disturbances before the meter. It is recommended to
follow the guidelines of CEN CR 13582.
