Abstract: This paper discusses a novel high-speed piston prover that uses a clearance seal to achieve very low uncertainties. We will review the instruments design and provide an uncertainty analysis for three sizes of our internal reference provers, designed for flows of 10 mL/min to 50 L/min. The results were expanded single-reading uncertainties at 2X coverage range from 0.064% to 0.073%. The instrument also has the capability to average a number of readings, potentially reducing the above uncertainties by a significant amount.
