8.1 Positioning the transducers
The U1000 V2 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.
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.
