Two-path measurement

The flow is measured redundantly at one measuring point in the case of two-path measurement.
The measured values of the two measuring channels can be processed and displayed differently. The
following measured values can be output for two-path measurement:
• Individual measured values per measuring channel (output independently of one another)
• The average of the two measured values.
The "Averaging" function generally provides you with a more stable measured value.
The function is thus suitable for measurements under conditions that are not ideal (e.g. short inlet
runs).
The two measuring channels can be configured individually. This makes it possible to independently
configure and select the display, outputs, sensor type and type of installation.
It is generally not necessary to individually configure the two measuring channels in the case of
two-path measurement. However, in certain situations individual channel configuration can be
used to balance out application-specific asymmetries.
