Installation in tanks containing one liquid and foam
•
Drill a pressure equalization hole in the stilling well above the maximum level.
•
Deburr the hole.
•
If the probe has a counterweight, make sure that there is enough space between the
counterweight and the wall of the stilling well.
Installation in tanks containing more than one liquid
•
Drill a pressure equalization hole in the stilling well above the maximum level of the top liquid.
•
Drill more holes along the length of the stilling well. Distance between holes
≥
25 mm / 1
¨
(depends on the minimum layer to be measured)
i
These holes help the liquids to move freely.
•
Deburr the holes.
•
If the probe has a counterweight, make sure that there is enough space between the
counterweight and the wall of the stilling well.
Floating roofs
If the device is for a tank with a floating roof, install it in a stilling well.
