Abstract
An apparatus for increasing the accuracy of meter factors of a flow instrument in conjunction with a prover having upstream and downstream prover detection switches and a flow computer including a computer program embodied on a computer readable medium for correcting errors in a meter factor of the flow instrument measured in a proving run and correcting effects of flow rate changes during proving. A computer program embodied on a computer readable medium whose contents causes a processor to increase the accuracy of meter factors of a flow instrument in conjunction with a prover having upstream and downstream prover detection switches and a flow computer. A method for increasing the accuracy of the meter factors of a flow instrument in conjunction with a prover having upstream and downstream prover detection switches and a flow computer.
