Liquid Velocity

Damping

The damping of the liquid velocity comes in addition to the damping set for the volume flow. The damping makes it possible to damp the fluctuations of the measured values of the liquid velocity:
  • on the display,
  • on the PLC inputs.
The damping of the liquid velocity comes in addition to the damping set for each analog output.
The damping is not applied to the new measured value if the 2 following conditions are met:
  • a Low, Medium or High damping level is active,
  • and the variation between 2 values that are measured one after the other is higher than 30 % (for example when charging the pipe or stopping the flow).
By default, the liquid velocity values are not damped.
