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
1)
B Horizontal orientation, transmitter at
top
A0015589
2)
Exceptions:
→ 6, 23
C Horizontal orientation, transmitter at
bottom
A0015590
3)
Exceptions:
→ 6, 23
D Horizontal orientation, transmitter at
side
A0015592
1) This orientation is recommended to ensure self-draining.
2) Applications with low process temperatures may decrease the ambient temperature. To maintain the
minimum ambient temperature for the transmitter, this orientation is recommended.
3) Applications with high process temperatures may increase the ambient temperature. To maintain the
maximum ambient temperature for the transmitter, this orientation is recommended.
If a sensor is installed horizontally with a curved measuring tube, match the position of the
sensor to the fluid properties.
A0028774
6 Orientation of sensor with curved measuring tube
1 Avoid this orientation for fluids with entrained solids: Risk of solids accumulating.
2 Avoid this orientation for outgassing fluids: Risk of gas accumulating.
