Stilling wells - general notes
Installation in tanks containing one liquid and foam
Drill an air circulation hole (max. Ø10 mm / 0.4¨) in the stilling well above the maximum level.
Remove the burr from the hole.
Installation in tanks containing one liquid or more without foam
Drill an air circulation hole (max. Ø10 mm / 0.4¨) in the stilling well above the maximum level.
Drill 1 or more liquid circulation holes in the stilling well (if there is more than 1 liquid in the
tank).
i These holes help the liquid to move freely between the stilling well and the tank.
Remove the burr from the hole.
Stilling wells - reference point
We recommend that you attach a flat cruciform target at the bottom of the stilling well. It must
have a width of 1/3 of the internal diameter of the stilling well tube. This target is the limit of the
measuring range in the stilling well.
