Note: It is possible to enter in the flow rate calculation a chord external to the converter (for example, a
Doppler velocity measurement). The settings to be defined for this chord are the same as those for the
internal chords, but the following must also be defined:
•
the internal chord associated with the external chord: when the internal chord is faulty, the external
chord takes over.
•
the input module which will serve as a velocity measurement: a 4-20 mA module may be used to
recover a Doppler velocity.
The main advantage of this virtual chord lies in being able to measure the flow using several measurement
methods.
