Process noise damping
Noise damping function
The dynamic sensitivity of the flow measurement signal to rapid changes in process flows
can be reduced by use of the process noise damping function. The function is typically used
in environment with:
● Strongly pulsating flow
● Changing pump speeds
● Large pressure variations
Process noise damping settings
Reduce interfering process noise by increasing the setting of the parameter Process Noise
Damping (Modbus address 2130).
● Centrifugal pump (1: low)
● Triplex pump (2)
● Duplex pump (3)
● Simplex pump (4)
● Cam pump (5: high)
The default value is Duplex pump. The damping affects all functions and outputs of the
sensor.
