Installation
Orientation
Vertical
Recommended orientation with upward direction of flow (View A). With this orientation,
entrained solids will sink and gases will rise away from the sensor when the fluid is stagnant.
The piping can be completely drained and protected against solids buildup.
Horizontal
In the recommended installation range in a horizontal installation position (View B), gas and air
collections at the pipe cover and problematic deposits at the bottom of the pipe have a smaller
influence on measurement.
