The electronics includes a signal processor configured to receive a flow signal from a flow sensor that is configured to measure a flow rate of the pulsating flow, generate a flow rate signal and a noise reference signal from the flow signal, and generate a cancelling signal from the noise reference signal. The electronics also includes a controller coupled to the signal processor and configured to determine a flow rate control signal. The electronics includes a signal generator communicatively coupled to the signal processor and the controller and configured to receive the flow rate control signal, generate a valve signal based on the flow rate control signal and the cancelling signal, and provide the valve signal to a valve to control flow rate and attenuate pulses of the pulsating flow of the fluid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active cancellation of a pulsating flow with a flow signal noise reference","description":"An electronics for active cancellation of a pulsating flow with a flow signal noise reference.
