Measuring mode
Two-path measurement with FlowDC
2)
(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). This is independent of the rotation position of the
two sensor sets on the measuring pipe.
The measured values of both sensor sets are averaged. Based on this average measurement value,
the measured value is compensated depending on the type of disturbance and the distance from the
measuring point to the disturbance point. This makes it possible to maintain the specified accuracy
and repeatability for measurements in non-ideal conditions (e.g. short inlet runs), with inlet runs up
to only 2x DN before and after the measuring point.
The configuration of the two measuring paths is only performed once and is adopted for both
measuring paths.

Single-path measurement (alternative configuration)
In the case of single-path measurement, the flow is measured at the measuring point without the
option of compensation.
For this, it is necessary to comply strictly with the specified inlet and outlet runs after the
disturbance points (e.g. curves, extensions, reductions) in the pipe.
To ensure the best possible measurement performance and measuring accuracy, the standard
configuration with two sensor sets

with FlowDC is recommended.
