4.10 Damping
Damping helps the transmitter smooth out small, rapid measurement fluctuations. A damping value
specifies the period of time, in seconds, over which the process variable value will change to reflect
63% of the change in the actual process.
• A high damping value makes the output appear to be smoother because the output must change
slowly.
• A low damping value makes the output appear to be more erratic because the output changes
more quickly.
Damping can be configured for flow, density, and temperature (see Sections 4.3.2, 4.7.3, and 4.8.2.).
When you specify a new damping value, it is automatically rounded down to the nearest valid
damping value. Valid damping values are listed in Table 4-8.
Note: For gas applications, Micro Motion recommends a minimum flow damping value of 2.56.
Before setting the damping values, review the following sections for information on how the damping
values interact with other transmitter measurements and parameters.
