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 filled
measuring pipes in the event of outgassing fluids or variable process pressures.
Vertical

Optimum for self-emptying pipe systems and for use in conjunction with empty pipe
detection.
Horizontal

1 EPD electrode for empty pipe detection
2 Measuring electrodes for signal detection
3 Reference electrode for potential equalization
• The measuring electrode plane must be horizontal. This prevents brief insulation of
the two measuring electrodes by entrained air bubbles.
• 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.
Inlet and outlet runs
If possible, install the sensor upstream from fittings such as valves, T-pieces or elbows.
Observe the following inlet and outlet runs to comply with accuracy specifications:
