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.

For very heavy sensors
If the nominal diameter DN
³
350 (14 in), mount the sensor on a foundation of adequate load-
bearing strength.
NOTICE
Very heavy!
Risk of damaging the metal casing and the internal magnetic coils.
►
Do not support the weight of the sensor on the metal casing.

Orientation
The direction of the arrow on the sensor nameplate helps you to install the sensor according to the
flow direction (direction of medium flow through the piping).
An optimum orientation position helps avoid gas and air accumulations and deposits in the measuring
tube.
The measuring device also offers the empty pipe detection function to detect:
• Partially empty measuring pipes
• Outgassing fluids
• Applications with variable process pressures
Vertical
This is the optimum orientation for self-emptying piping systems and for use in conjunction with
empty pipe detection.
