5.2 Interference in the pipe system
Components integrated in the pipes, bends, valves, reductions, etc� lead to turbu-
lence of the medium� This affects the function of the unit�
►
Adhere to the distances between sensor and sources of interference:
S
S
5...10 x D
3...5 x D
D = pipe diameter; S = sources of interference
5.3 Alignment
►
To achieve the optimum measuring accuracy: mount the sensor in a way that
the flow goes to the larger of the two key surfaces (1)�
On units with an external thread, a bore hole in the key surface (2) indi-
cates the flow direction�
