Orientation
The sensor operates in all orientations, but Siemens has the following recommendations:
• Vertical installation with an upwards 󹪞ow
Figure4-7 Vertical orientation, upwards 󹪞ow
NOTICE
Abrasive liquids / liquids containing solid particles
A vertical installation minimizes wear and deposits in the sensor
Note
Gas/air bubbles in the liquid
A vertical installation minimizes any negative e󹪜ect of gas/air bubbles in the liquid
• Horizontal installation, terminal box upwards or downwards
Figure4-8 Horizontal installation, various terminal box positions
NOTICE
Do NOT mount the sensor with the terminal box sideways
This will position the electrodes at the top where there is possibility for air bubbles and at
the bottom where there is possibility for mud, sludge, sand etc.
Note
Empty pipe detection
For applications with empty pipe detection, the sensor can be tilted 45°, as shown above.
