Mounting location
Correct measuring is possible only if the pipe is full. Avoid the following locations:
• Highest point of a pipeline. Risk of air accumulating.
• Directly upstream of a free pipe outlet in a vertical pipe.
Vertical pipes
Notwithstanding the above, the installation proposal below permits installation in an open vertical
pipe. Pipe restrictors or the use of an orifice with a smaller cross-section than the nominal diam-
eter prevent the pipe from running empty while measurement is in progress.
Installation in a vertical pipe
1 = Supply tank, 2 = Flow measuring sensors, 3 = Orifice plate, pipe restriction, 4 = Valve, 5 = Filling tank
