If possible, install the flow measuring sensors well clear of fittings such as valves, T-pieces,
elbows, etc. If several flow obstructions are installed, the longest inlet or outlet run must be con-
sidered. Compliance with the following requirements for the inlet and outlet runs is recommended
in order to ensure measuring accuracy.

1 = Valve, 2 = Pump, 3 = Two pipe bends in different directions
Shielded cables are offered in the following lengths:
5 m and 10 m
In order to ensure measuring accuracy, comply with the following instructions during installation:
Route the cable well clear of electrical machines and switching elements.
Environment
• Transmitter Prosonic Flow 92:
