Damping smooths the flow rate output and optimises the flowmeter's response time to
the control system.
Damping is an exponential filter with a selectable time constant; it can be set between 0
and 32 seconds.
An eight second damping factor will pass 64% of the step change in this time period.
Damping applies to all outputs except the raw pulse output where no damping is
applied to the direct vortex shedding frequency.
Flow rate available as a 4...20 mA signal with the 20 mA value being set by the
configured full range flow rate.
