3.4.3 Pipelines with control valve

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.

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
