Free-field measurement with flooding protection tube
The flooding protection tube ensures the sensor measures the maximum level even
if it is completely flooded.
In free-field installations and/or in applications where there is a risk of flooding,
the flooding protection tube must be used.
The flooding protection tube can be ordered as an accessory or together with the device
via the ordering option Accessory enclosed .
Figure 10.8 Function of flooding protection tube
The tube is screwed directly onto the sensor and seals off the system by means of an O-ring
making it air-tight. In the event of flooding, the air pocket that formed in the tube ensures
the measurement of the maximum level at the end of the tube. Due to the fact that the blocking
distance is inside the tube, multiple echoes are not analyzed.
