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

1) Applications with low process temperatures may reduce 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.
If a sensor is installed horizontally with a curved measuring tube, match the position of the sensor to
the fluid properties.

 18 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.
Inlet and outlet runs No special precautions need to be taken for fittings which create turbulence, such as valves, elbows
or T-pieces, as long as no cavitation occurs (→  47).
