Performance characteristics

Every application is different in terms of its shapee (such as influential reflexion edges), medium as

well as the properties of the medium (such as attenuation and moisture levels) and therefore always

requires an individual basic setup of the flow indicator.

The ambient temperature has no direct influence on the measuring system (FTR20 is temperature-

compensated internally)�

Distance of FTR20 from the medium

The measuring signal is influenced by the distance between the device and the medium. With

significantly deviating distances, the device should be installed, if possible, such that the distance

is as constant as possible. If this is not possible, the flow indicator must be adjusted under the least

favourable conditions in this case too�
