Title: Innovations of David Winsor Marsh
Introduction
David Winsor Marsh is an accomplished inventor based in North Scituate, Rhode Island. He holds three patents that showcase his expertise in the field of measurement systems and fluid dynamics. His innovative contributions have significantly advanced the technology used in conductivity measurement and fluid flow monitoring.
Latest Patents
One of his latest patents is for the "Calibration of Conductivity Measurement System." This invention provides a system and method for calibrating a digital conductivity and temperature measuring system. A connector is interposed between a sensor and transmitter of the system, allowing for accurate calibration using selectable resistors with known values. The sensor measures a raw resistance for a selected resistor, and the system calculates a calibration factor by comparing the raw resistance to the known value.
Another notable patent is the "Ultrasonic Vortex Flowmeter Having Remote Signal Processing." This improved ultrasonic vortex fluid flowmeter features a sensor housing that includes a slip-on yoke portion, which can be easily attached to a bluff body conduit connector. This design eliminates the need to shut down fluid flow during servicing and prevents external contaminants from entering the fluid. The control and processing circuitry is located remotely to enhance the isolation of the sensor from the monitored fluid conduit.
