6.Internal damping filters out noise or the effects of rapid changes in the variable without affecting measurement accuracy.
The damping value is the filter coefficient that approximates the time required for the output to achieve 63% of its new value in response to a step change at the input. The actual time depends on many factors, including sensor type and density of the process fluid. The meter rounds down the chosen damping value to the nearest programmed filter coefficient. Programmed filter coefficients, in seconds, are:
0.1 0.2 0.4 0.8 1.6 3.2 6.4 12.8
If desired, enter an internal damping value into the Damping text box in the Flow panel.
