Abstract
A flow meter filter system (200) according to an embodiment of the invention includes a noise pass filter (203) configured to receive a first version of a flow meter signal and filter out the flow meter data from the flow meter signal to leave a noise signal, a noise quantifier (204) configured to receive the noise signal from the noise pass filter (203) and measure noise characteristics of the noise signal, a damping adjuster (205) configured to receive the noise characteristics from the noise quantifier (204) and generate a damping value based on the noise characteristics, and a filter element (206) configured to receive a second version of the flow meter signal and receive the damping value from the damping adjuster (205), with the filter element (206) being further configured to damp the second version of the flow meter signal based on the damping value in order to produce a filtered flow meter signal.
