Overview
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 Flow Damping to the value you want to use.
The default value is 0.8 seconds. The range depends on the core processor type and the
setting of Update Rate, as shown in the following table.

The value you enter is automatically rounded off to the nearest valid value. For example, if
the damping is currently set to 0.8 seconds, any value entered up to 1.2 seconds will be
rounded down to 0.8 seconds, and any value entered from 1.21 to 1.59 seconds will be
rounded up to 1.6 seconds.
