Title: Innovations by Donald B Heckman
Introduction
Donald B Heckman is a notable inventor based in Purcellville, Virginia, with a significant contribution to the field of flow measurement technology. He holds four patents that showcase his innovative approach to fluid dynamics and measurement systems. His work has been instrumental in advancing the efficiency and accuracy of flow measurement devices.
Latest Patents
One of his latest patents is the "Open channel flowmeter utilizing surface velocity and lookdown level." This invention features a flowmeter that employs velocity measurements at the fluid surface and lookdown level sensors, allowing installation without requiring entry into a manhole. The system generates energy signal beams that reflect back to the sensors, producing a surface velocity signal based on the Doppler frequency shift. This signal is then modified to yield a mean velocity signal, while a level signal is derived from the air space between the sensor and the fluid surface. This innovative approach enables accurate fluid flow calculations based on the mean velocity and fluid level signals.
Another significant patent is the "Port forward sensor for liquid level gauge or flowmeter." This improved sensor measures the level of liquid flowing in a conduit or pipe. It features an initially air-filled pressure transmitting passage that communicates between a pressure port and a pressure transducer. The design allows hydraulic pressure to force liquid into the passage, compressing the air and exerting pressure on the transducer that corresponds to the liquid level. The unique cross-sectional area and high surface energy of the material used prevent liquid migration to the transducer, enhancing measurement reliability.
