Material cone
Note when installing the electrodes into the
vessel, that material cones can be caused with
solids which can change the switch point. We
recommend to choose an installation place
where the electrode detects an average value
of the material cone.
According to the position of the filling and
emptying opening in the vessel, the electrode
must be installed appropriately. To
compensate meas. errors caused by the
material cone, you should install the electrode
at a distance of approx.
d /
6
from the vessel wall.
