3.2 Installation conditions
3.2.1 Dimensions
The dimensions and the fitting lengths of the measuring sensors and the transmitter are
on Page 152 ff.
3.2.2 Mounting location
Correct measuring is possible only if the pipe is full. Avoid the following mounting
locations:
Do not install at the highest point in the run. Risk of air accumulating.
Do not install directly upstream from an open pipe outlet in a down pipe.
Fig. 4: Mounting location
Down pipes
Notwithstanding the above, the installation proposal below permits installation in an
open down pipe. Pipe restrictions or the use of an orifice plate with a smaller cross-
section than the nominal diameter prevent the pipe from running empty while
measurement is in progress.
