9.7 Internal damping
Enter internal damping values into the Damping text boxes under Flow,
Density, and Temperature.
Internal damping filters out noise or the effects of rapid changes in the
variable without affecting measurement accuracy. All transmitters use a
digital emulation of a Resistance Capacitance low-pass filter.
• The RFT9739 implements a selective digital filter on the flow, density,
and temperature outputs.
• The IFT9701 and IFT9703 implement damping by emulating the
effect of a low-pass resistance-capacitance (RC) filter on the flow
output.
• The RFT9712 and RFT9729 implement damping by emulating the
effect of a low-pass resistance-capacitance (RC) filter on the flow
and density outputs.
