Flow meter filter system and method

摘要

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.
