Obstacles inside the tank
Rough-surface liquids or liquids which can foam

°
min. 80 mm
min. 30 cm
The fixed obstacles inside the tank may
generate false echos.
Ensure there is no obstacle within the beam
cone.
If this is impossible, mask the obstacles by
means of deflectors or use a meter tube as
for the rough-surface liquids (see hereafter).
When the tank filling-up generates waves or
foam, extend the meter tube as far as under
the surface of the liquid.
A meter tube makes it also possible to have
stable measurements. It makes it possible to
ignore the obstacles inside the tank.
The meter tube cannot be used with
clogging products.
