Abstract of the Disclosure Apparatus for calibrating a fluid flow meter under test is disclosed as including a meter prover for directing a known volume of fluid through the meter including a chamber of known volume, a piston to be moved rectilinearly within the chamber and a motor for driving the piston, the chamber being coupled to the fluid flow meter under test to permit the flow of fluid between the fluid flow meter and the chamber. There is included a measuring device in the illustrative form of a rotary encoder coupled to the fluid flow meter to provide a first indication in the form of a first series of pulses indicative of the fluid flow as measured by the meter, and a second measuring device in the illustrative form of a high precision linear encoder coupled to the meter prover. The linear encoder is responsive to the movement of the piston for providing a second indication in the form of a second series of pulses indicative of the fluid drawn by the meter prover through the fluid flow meter. A control circuit in the form of a microprocessor is responsive to the movement of the piston to enable the accumulation of the outputs of the first and second measuring devices, e.g., counting the first and second series of pulses, and for terminating the accumula- tion, e.g., counting the first and second series of pulses, upon the accumulation of a given quantity or number of the first series of pulses, whereby the accumulated value or number of the second series of pulses provides a calibrated, precise manifestation of the fluid flow through the fluid flow meter as measured by the meter prover.
