Fitting the sensor in
the in-line probe housing Observe the operation and safety instructions contained in the
ProMinent ®
• Ensure the flow does not fall below the minimum flow rate
of 20 l/h! Monitor the flow on the connected measurement
and control equipment. If the measured value is used as a
control, switch off the control by reducing to below the
minimum flow rate or switch to basic load.
• Use the sensor only in in-line probe housing types DLG III A
(914955), DLG III B (914956) or DGM (module 25 mm) in order
to guarantee the required flow conditions!
There is no guarantee provided for use with other in-line
probe housings.
• Avoid installations which allow air bubbles to build up in the
sample water.
Air bubbles that cling to the diaphragm of the sensor can
cause the measured value to be too small and thus may lead
to incorrect metering in the control system.

DLG III Push the O-ring up over the sensor as far as the terminal block.
Insert the sensor into the DLG III.
Tighten the sensor with thread plugs.
DGM Push the O-ring up over the sensor as far as the terminal block;
leave a plain washer in the DGM.
Insert the sensor nto the DGM and fit tightly with terminal screw
until the O-ring is sealed: the terminal block determines the
correct depth for fitting the sensor.
