3.4.3 Pipelines with control valve
3.4.4 Preferred mounting position
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 3-4: Pipeline with control valve
1 Recommended: installing the device upstream
