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).
Orientation Recommendation
A Vertical orientation
A0015591
B Horizontal orientation, transmitter at
top

1)
C Horizontal orientation, transmitter at
bottom
A0015590

3)
D Horizontal orientation, transmitter at
side
A0015592
1) Applications with low process temperatures may decrease the ambient temperature. To maintain the
minimum ambient temperature for the transmitter, this orientation is recommended.
2) Applications with high process temperatures may increase the ambient temperature. To maintain the
maximum ambient temperature for the transmitter, this orientation is recommended.
3) To prevent the electronics module from overheating in the case of a sharp rise in temperature (e.g. CIP or
SIP processes), install the device with the transmitter component pointing downwards.
Horizontal
• Ideally, the measuring electrode plane should 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.

1 EPD electrode for empty pipe detection
2 Measuring electrodes for signal detection
3 Reference electrode for potential equalization
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:
