3.2 Installation conditions
3.2.1 Installation dimensions
The dimensions and the fitting lengths of the sensors and the transmitter are on Page 104 ff.
3.2.2 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.
