Abstract
An electronic filter for conditioning a primary flow signal including alternating electrical signals generated in a flowmeter comprises a parallel bank of low frequency bandpass filters and high frequency bandpass filters, wherein the switching on or off of the individual low frequency bandpass filter is controlled by a command signal generated from an auxiliary flow signal provided by an accessory flowmeter supplying a crude but stable signal representing the level of fluid flow, and the switching on and off of the individual high frequency bandpass filters is controlled by a command signal generated from the frequency of the primary flow signal providing a highly accurate and extremely sensitive signal that represents the time rate of fluid flow.
