OPERATION MT100 Multipoint Flow Meter
Flow Damping
The flow meter has a flow damping setting that is used to smooth out the flow signal output for applications in which process conditions are
erratic. Use the configurator software to adjust the flow damping setting (Advanced Setup/User Parameters) as required for your
application. Refer to the MT100 Configuration Software manual 06EN003461 for details.
As shown in Figure 33 below, an increase in flow damping value results in an output that is increasingly resistant to change (amplitude
variations). Compare the chart’s blue curve (value = 0.25 for 0% flow damping) with the chart’s black curve (value = 5.00 for 95% flow
damping). The black curve shows signal excursions that are much more constrained relative to the blue curve.
The minimum value that can be entered is 0.25 (0% flow damping). It is possible to enter a number greater than 5.0 (95% flow damping).
The practical limit, however, is 5.0 since 100% flow damping will never be attained regardless of the entered value.
High flow damping values results in reduced flow response. Make sure that alarm conditions are not affected when
using the flow damping feature.
