3.4.3 Pipelines with control valve
3.4.4 Preferred mounting position for device without pressure sensor
INFORMATION!
To ensure smooth and correct measurement, the manufacturer recommends not installing the
measuring device downstream from a control valve. This would run the risk of vortex formation,
which would distort the measuring result.
Figure 3-6: Pipelines with control valve
1
Recommended: installing the device before the control valve at a distance of
5 DN
2
Not recommended: installing the device directly downstream of control valves, due to vortex formation
