Down pipes

Notwithstanding the foregoing, the installation suggested below permits installation in an open
down pipe. Pipe restrictions or the use of an orifice plate with a smaller cross-section than the
nominal diameter prevent the pipe from running empty while measurement is in progress.

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.
