Orientation
Make sure that the direction of the arrow on the nameplate of the sensor matches the direction of flow
(direction of fluid flow through the pipe.
Vertical (view V)
Recommended orientation with upward direction of flow. When fluid is not flowing, entrained solids will sink
down and gases will rise away from the measuring tube. The measuring tubes can be completely drained and
protected against solids buildup.
Horizontal
The transmitter can be installed in any orientation in a horizontal pipe run.
m
= To ensure that the maximum permitted ambient temperature for the transmitter (–20 to +60 °C,
optionally –40 to +60 °C) is not exceeded, for low-temperature fluids, we recommend the horizontal
orientation with the transmitter head up (Fig. H1) or the vertical orientation (Fig. V).
