Abstract: The Sprague Pressure Pulse Prover is a new approach to automatic meter proving that represents a significant improvement in proving speed, versatility and reliability. Extensive testing of both 4 chamber and 3 chamber gas meters has shown that the differential pressure absorbed to operate gas meters has a fixed wave form for each particular meter. Additionally it has been demonstrated that this wave form is extremely repeatable from one cycle of the meter mechanism to the next. This information led to the development of the pressure pulse prover which utilizes the differential pressure pattern of any particular meter to control the operation of the pressure pulse automatic prover. Many unique features are provided by this latest type automatic prove
