Title: METHOD AND SYSTEM FOR COMMUNICATION BY CONTROLLING THE FLOWRATE OF A FLUID
Abstract:
A method and system of communicating with a device by controlling the flow rate of a fluid. The method comprises transmitting an encoded message with a flow control device by controlling the flow rate of a fluid and generating a signal indicative of the flow rate with a receiver. The method also comprises decoding the message by analyzing the signal using amplitude shift-keying. The system comprises a flow control device, a receiver, and a controller. The flow control device is in fluid communication with a tubular string and transmits an encoded message by controlling the flow rate of the fluid flowing through the tubular string. The receiver generates a signal indicative of the flow rate of the fluid in the tubular string. The controller is in communication with the receiver and decodes the message by analyzing the signal using amplitude shift-keying.
