Installation in partially filled pipes
A partially filled pipe with a gradient necessitates a drain-type configuration. The empty pipe
detection (EPD) function offers additional protection by detecting empty or partially filled pipes.
• Do not install the sensor at the lowest point in the drain: risk of solids accumulating.
• It is advisable to install a cleaning valve.

Orientation
The direction of the arrow on the sensor nameplate helps you to install the sensor according to
the flow direction.
An optimum orientation position helps avoid gas and air accumulations and deposits in the
measuring tube.
Vertical
This is the optimum orientation for self-emptying piping systems and for use in conjunction with
empty pipe detection.

Horizontal
The measuring electrode plane must be horizontal. This prevents brief insulation of the two
measuring electrodes by entrained air bubbles.
With horizontal orientation, empty pipe detection only works if the transmitter housing is
pointing upwards as otherwise there is no guarantee that the empty pipe detection function
will actually respond to a partially filled or empty measuring tube.
