Patent number: 11867546Abstract: A system includes upstream process equipment and downstream process equipment. The upstream process equipment is configured to transmit a predetermined fluid to the downstream process equipment. A manually operated valve fluidly couples the upstream process equipment to the downstream process equipment. A removable ultrasonic wireless flow meter is coupled to piping downstream from the manually operated valve. A control system is coupled to the manually operated valve and the removable ultrasonic wireless flow meter. The control system determines an optimum time and speed to actuate the manually operated valve using a predictive model based on a valve size of the manually operated valve, a valve age of the manually operated valve, fluid type, a criticality index of the manually operated valve, a measured flow rate from the removable ultrasonic wireless flow meter, and corresponding coefficients.Type: GrantFiled: January 19, 2022Date of Patent: January 9, 2024Assignee: SAUDI ARABIAN OIL COMPANYInventors: Mishal Alsaiari, Abdulaziz Moshaweh, Mohammed A.
