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.

Figure 3-4: Pipeline with control valve

1Recommended: installing the device upstream from the control valve at a distance of 5 DN

2Not recommended: Installing the flowmeter directly downstream of control valves, due to vortex formation.

3.4.4Preferred mounting position

Preferred mounting position

1Above a horizontal pipe

2underneath a horizontal pipe (not permitted with lines at risk for condensate )

3On a vertical pipe

INFORMATION!

Depending on the installation position, you may have to rotate the display and/or the connection housing. For further information refer to Turning the display on page 24.
