Title: Innovations of William Stephen Woodward
Introduction
William Stephen Woodward is an accomplished inventor based in Chapel Hill, NC (US). He holds two patents that showcase his expertise in fluid measurement technologies. His innovative contributions have significantly advanced the field of acoustic flow measurement.
Latest Patents
One of his latest patents is the Acoustic Displacement Flowmeter. This device determines the flow rate of a fluid in a path containing a controllable valve. It establishes fluid flow along the path, directing it to a transducer with a displacement element. The flow path is restricted to generate a signal from the transducer, which represents displacement due to fluid flow. The transducer is then used to determine the fluid flow rate, and the flow path is reestablished by removing the restriction. The transducer signal helps calculate the flow rate by providing an analog reference signal, integrating it for a predetermined time, and using the time required for the deintegration signal to reach a threshold value. A temperature correction signal is also generated to adjust the calculated flow rate for temperature variations.
Another significant patent is the Method and System for Digital Measurement of Acoustic Burst Travel Time. This invention determines fluid flow along a path by measuring the travel time between two transducers of oppositely traveling acoustic burst waves. The phase difference between the received signals and phase reference signals is calculated to determine flow velocity. The transducer drive signals are adjusted to minimize phase differences, ensuring accurate measurements.
