Strong product movements
Heavy turbulences in the vessel, e.g. by
strong stirrers or strong chemical reactions,
aggravate the measurement. A surge or
bypass pipe (figure) of sufficient size always
allows, provided that the product causes no
build-up in the pipe, a reliable measurement
even with strong turbulences in the vessel.

The max. height of water to be expected
determines the installation height to keep the
min. distance of the transducer even with
highest high water. The low water edge
should be covered with a shield in the trans-
ducer range.
Inflowing material
Do not mount the instrument in or above the
filling stream. Ensure that you detect the
product surface and note the inflowing mate-
rial.
Mounting on the vessel
If the sensor is mounted too close to the
vessel wall, build-up and adhesion of the
filling material to the vessel wall cause false
echoes. Please position the sensor at a suffi-
cient distance from the vessel wall. Please
also note chapter "4.1 General installation
instructions".
