Installation location

Correct measuring is possible only if the pipe is full. Avoid the following installation
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.

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.
