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
Flow sensor and any mounted blind plug can be
used in connection with both PN16 and PN25.
The flow sensor is available with either PN16
or PN25 marking as required. Any provided
extensions and glands can be used for both
PN16 and PN25.
In connection with flow sensors with the
nominal dimensions G¾Bx110 mm and
G1Bx110 mm, it must be checked if the thread
run-out is sufficient.
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.
