Line cross sections
By reducing line cross sections you have the possibility of installing smaller sensors in pipes
of larger rated widths.
This has the advantage that the speed in the sensor increases with small flows and thus a
better measuring accuracy is achieved.
To avoid the formation of eddy currents in the sensor, the angle of reduction should not be
greater than 8°.

Note
Reductions cause losses in pressure.
