The selection "Standpipe" opens a new window in which the inner
diameter of the applied standpipe is entered.
Following the characteristics of the applications and the metrological
features of the sensor are described.
Note:
Probably the operation of the instrument in these applications is sub-
ject to national restrictions in respect to the radio license (see chapter
"For your safety"):
