Prosonic Flow 92 3 Installation
Hauser 15
3.2.3 Orientation
Vertical orientation
Recommended orientation with upward direction of flow (View A). Entrained solids sink
down. Gases rise away from the measuring sensor when fluid is not flowing. The piping
can be completely drained and protected against build-up.
Horizontal orientation
In the recommended installation range (C) with horizontal orientation (View B), gas and
air collections at the top of the pipe and problematic deposits at the bottom of the pipe
have a minor influence on the measurement.
Fig. 6: Orientation (A = Vertical, B = Horizontal, C = Recommended installation range max. 120°)
3.2.4 Inlet and outlet runs
If possible, install the sensor well clear of assemblies 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 rec-
ommended to ensure measuring accuracy:
