Strong product movements
Strong turbulence in the vessel, e.g. caused
by powerful agitators or strong chemical
reactions, can seriously interfere with the
measurement. A surge or bypass tube (see
illustration) of sufficient size always enables
reliable and problem-free measurement even
if strong turbulence occurs in the vessel,
provided there is no product buildup in the
tube.
Products with a tendency to light buildup can
be detected by using a measuring tube with
100 mm nominal width or larger. In such a
measuring tube, light buildup does not cause
any problems.
Buildup
If the sensor is mounted too close to the
vessel wall, product buildup and other de-
posits on the vessel wall cause false echoes.
Position the sensor at a sufficient distance
from the vessel wall. Please also note chapter
"4.1 General installation instructions“.
Inflowing material
Do not mount the instrument in or above the
filling stream. Ensure that you detect the
product surface and not the inflowing mate-
rial.
