Overview
Velocity Damping controls the amount of damping that is applied to the velocity
measurement.
Damping is used to smooth out small, rapid fluctuations in process measurement. Damping
Value specifies the time period (in seconds) over which the transmitter will spread changes
in the process variable. At the end of the interval, the internal value will reflect 63% of the
change in the actual measured value.
Procedure
Set Velocity Damping to the value you want to use.
The default value is 0.8 seconds. The range is 0.0–51.2 seconds.
The value is automatically rounded down to the nearest valid value. Valid values are as
follows: 0, 0.2, 0.4, 0.8, … 51.2.
4.5.3 Configure Flow Direction

ProLink III Device Tools > Configuration > Process Measurement > Velocity > Flow Direction

Overview
Flow Direction controls how forward flow and reverse flow affect velocity measurement and
reporting.
Flow Direction is defined with respect to the flow arrow on the sensor:
• Forward flow (positive flow) moves in the direction of the flow arrow on the sensor.
• Reverse flow (negative flow) moves in the direction opposite to the flow arrow on
the sensor.
Tip
Micro Motion sensors are bidirectional. Measurement accuracy is not affected by actual flow
direction or the setting of the Flow Direction parameter.
