6.6Configuring the damping values

A damping value is a period of time, in seconds, over which the process variable value will change to reflect 63% of the change in the actual process. Damping helps the transmitter smooth out small, rapid measurement fluctuations.

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.

When you specify a new damping value, it is automatically rounded down to the nearest valid damping value. Flow, density, and temperature have different valid damping values. Valid damping values are listed in Table 6-2.

For the Model 1500 transmitter with the filling and dosing application, the default damping value for flow has been set to 0.04 seconds. For most filling and dosing applications, the default flow damping value is used. Contact Micro Motion customer support before changing the flow damping value.

Before setting the damping values, review Sections 6.6.1 through 6.6.3 for information on how the damping values interact with other transmitter measurements and parameters.

6.6.1Damping and volume measurement

When configuring damping values, be aware that volume measurement is derived from mass and density measurements; therefore, any damping applied to mass flow and density will affect volume measurements. Be sure to set damping values accordingly.

6.6.2Interaction with the added damping parameter

The mA output has a damping parameter – added damping. If damping is configured for flow, the mA output is configured for mass flow or volume flow, and added damping is also configured for the mA output, the effect of damping the process variable is calculated first, and the added damping calculation is applied to the result of that calculation.

See Section 4.5.5 for more information on the added damping parameter.
