ABSTRACT:
In a prover loop used to calibrate positive displacement meters, such as those used on a LACT-unit (Lease Automatic Custody Transfer) in the petroleum industry, a control system is provided for operating the prover loop valve. This control system is designed to operate so that each prover loop test is conducted under identical conditions. The system design permits easy conversion from the conventional hydraulic systems.
