Identify suitable location for flow measurement

The GF U1000 V2 WM/WHM requires an even and uniform flow profile, since distortions in the flow can cause unpredictable
measurement errors.
In many applications, however, it is not possible to have a uniform flow rate through 360°. This may be, for example, because there
are air bubbles inside the top of the pipe, or turbulence in the pipe, or sludge at the bottom of the pipe.
Possible air gap
Possible deposits
(sludge)
5x inner diameter
Experience has shown that the most accurate results are obtained if the guide rail of the transducers is not mounted vertically to
the pipe, but turned at an angle of about 45° to the right
or left on the pipe.
Turbulent flow profile
Possible sensor position
Laminar flow profile
