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

B Horizontal orientation, transmitter at
top

1)
C Horizontal orientation, transmitter at
bottom
A0015590
2) 3)
D Horizontal orientation, transmitter at
side

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 (available from DN > 15 mm (¹⁄₂ in))
2 Measuring electrodes for signal detection
Measuring devices with a nominal diameter < DN 15 mm (¹⁄₂ in) do not have an EPD
electrode. In this case, empty pipe detection is performed via the measuring
electrodes.
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:
