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.
