Residual risks
3.5.1 Slippage of the sensor
If the sensor is inadequately secured, it may become loose due to the
pressure of the water or due to vibration. This results in the following
risks:
Due to the pressure of the water the sensor may slip out of the flow
chamber.
The sensor may slip down into the flow chamber due to its own
weight.
Depending on recommendation in the data sheet, use a variant with a
retaining ring (see section 1.2, p. 5).
Make sure that the screw fastening cannot come loose during
operation.
Check the sensor regularly for secure attachment.
3.5.2 Water pressure that is high or fluctuating
The membrane may be damaged if the water pressure exceeds the
maximum permissible value, or if the water pressure fluctuates greatly.
Comply with the permissible pressure stated on the data sheet (see
section 1.2, p. 5).
Keep the pressure constant.
