Measuring mode
Single-path measurement
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. elbows, extensions, reductions) in the measuring pipe.
To ensure the best possible measurement performance and measurement accuracy,
the configuration with two sensor sets
Two-path measurement
In the case of two-path measurement, the flow is measured by two measurements (two
measuring paths/sensor sets) at the measuring point.
For this purpose, the two sensor sets are installed at a measuring point with one or two
traverses. The sensors can generally be arranged in one or two different measuring planes.
For installation with two measuring planes, the sensor planes must be rotated by at least
30° in relation to the pipe axis.
