Installation

The sensors are to be mounted in such a way that the sample medium
flows directly into the sensor through the orifice at the tip and re-emerges
through the vent holes. Any other installation position of the sensors can
create the risk of formation of airlocks, or of contamination through depos-
its of solid matter.
Flow of medium must be accross the face of the sensor. Air bubbles and
solid matter deposits are to be avoided. A minimum clearance of 30 mm
(1.18") between sensor and pipe wall must be maintained (see drawing
above).
Vertical mounting (top entry) in a pipe is recommended only if the pipe is
full and no air bubbles are able to develop in the flow.
In the event of side mounting (side entry) of the sensor, vertical upward
flow of sample process medium must be ensured.
