Two-path measurement with FlowDC
1)
(standard configuration)
In the case of two-path measurement with FlowDC, the flow is measured by two
measurements at the measuring point.
For this, the two sensor sets are installed on the measuring pipe, offset at a specific angle
to one another (180° for 1 traverse, 90° for 2 traverses, angle tolerance ±5°). This
arrangement is independent of the circumferential position of the two sensor sets on the
measuring pipe.
The measured values of both sensor sets are averaged. The resulting measurement error is
compensated based on the type of interference, the distance from the measuring point to
the disturbance point, and the Reynolds number. The error-compensated average thus
ensures that the specified maximum measurement error and repeatability are maintained
even under non-ideal flow conditions (see for example → 6, 20).
The configuration of the two measuring paths is only performed once and is adopted for
both measuring paths.
