Patent ID: 7257495

Claim:
A flow meter filter system ( 200 ) comprising: 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.
