This patent describes a method for proof testing of an electronic gaseous fluid flow meter including a solid state fluid flow sensor and a signal processing circuit the flow sensor of the meter provides a signal output indicative of fluid flow measured thereby. The signal processing circuit of the meter includes timing means for generating periodically recurring timing signals defining sampling intervals for the meter, sampling means which samples the signal output of the fluid flow sensor during the sampling intervals to obtain flow measurement data representing the volume of fluid that has been passed through the meter, and memory means for storing the flow measurement data.
