Orientation
An optimum orientation helps avoid gas and air accumulations and deposits in the measuring tube. However,
the measuring device also offers the additional function of empty pipe detection (EPD) for detecting partially
filled measuring tubes or if outgassing fluids or fluctuating operating pressures are present.
Vertical orientation
This is the ideal orientation for self-emptying piping systems and for use in conjunction with empty pipe
detection.
Vertical orientation
Horizontal orientation
The measuring electrode axis should be horizontal. This prevents brief insulation of the two measuring
electrodes by entrained air bubbles.
Caution!
Empty pipe detection only works correctly with horizontal orientation if the transmitter housing is facing
upwards. Otherwise there is no guarantee that empty pipe detection will respond if the measuring tube is only
partially filled or empty.

1 EPD electrode for empty pipe detection (not for DN 2 to 15 / 1/12 to ½")
2 Measuring electrodes for signal detection
Vibrations
Secure the piping and the sensor if vibration is severe.
Caution!
If vibrations are too severe, we recommend the sensor and transmitter be mounted separately. Information on
the permitted shock and vibration resistance → ä 18, Section "Shock and vibration resistance".
