Do not mount the instrument in or above the

filling stream. Ensure that you detect the

product surface and not the inflowing mate-

rial.

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

"3.1 General installation instructions“.

Mounting and installation

Vessel installations

Vessel installations, such as e.g. ladders,

often cause false echoes. Make sure when

planning your measuring location that the

radar signals have free access to the meas-

ured product.

Ladder

Struts

Struts, like other vessel installations, can

cause strong false echoes that are superim-

posed on the useful echoes. Small baffles

effectively prevent a direct false echo recep-

tion. These false echoes are scattered and

diffused in the surrounding space and are

then filtered out as "echo noise“ by the meas-

uring electronics.
