Types and versions
The antenna is available with or without horn.
Versions with horn are characterised by very
good antenna gain. High measurement reli-
ability can be achieved even in case of prod-
ucts with very poor reflective properties. The measuring tube acts as a conductor for
radar signals. The running period of the ra-
dar signals changes in the tube and de-
pends on the tube diameter. The tube inner
diameter must be programmed into the sen-
sor so that it can take the altered running time
into account and deliver precise level signals.
