  • Autonomous inflow control device for live flow monitoring
    Patent number: 11480029
    Abstract: A production system and method of operating the production system. A fluid flows through a flow control device. The flow control device having an element that generates an acoustic signal indicative of a value of a parameter of the fluid in response to the fluid flowing through the flow control device. The processor receives the acoustic signal from the element, determines the value of the parameter of the fluid from the parameter of the acoustic signal, and changes an operation of the production system based on the value of the parameter of the fluid.
