Orientation

Vertical orientation
We recommend the sensor be mounted where there is upward direction of flow. With this
orientation, entrained solids will sink down and gases will rise away from the sensor when the fluid
is stagnant.
Horizontal orientation
We recommend the sensors be mounted within an angle of ±60° to the horizontal (area shaded gray
in the graphic). With this orientation, flow measurement is less affected by any gas or air
accumulation in the upper area of the pipe or by buildup at the bottom of the pipe.
