✓
Make sure that the membrane does not come into contact with
other objects to avoid damage and obstruction of the membrane.
✓
Once the probe has been positioned on the probe holder, it is
recommended to slowly open the delivery cock to protect the
membrane from the pressure front produced by the water flow.
✓ After installation, the sensor must always be kept wet, e.g. the
probe holder must never run dry.
2.5 F
LOW ADJUSTMENT
To ensure correct operation of the probe, the flow rate of fluid passing through
the probe holder must be between 30 l/h and 60 l/h and with a pressure
between 0 bar and 1 bar (the recommended working range for probe is 0.3 -
0.5 bar).

ATER FLOW
Do not exceed the recommended working range:
✓
do not use the sensor with a lower or higher range than the indicated
limits;
✓
before commissioning the probe, the flow rate must be measured
using suitable measurement methods.
INSTALLATION INSTRUCTIONS
Avoid installations that create air bubbles in the sample water. The air bubbles
adhering to the sensor membrane can cause an insufficient measurement
value. An insufficient measured value can lead to incorrect dosing in a control
circuit.
