INSTALLATION
The fixed obstacles inside the tank may genera-
te 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.
