Patent number: 8960220Abstract: A liquid mass measurement and fluid transmitting apparatus includes a container for measurement of a mass of fluid therein. A sensor is coupled to the container which measures a mass of fluid within the container independent of variations of pressure within the container. A diaphragm sensor may be located on the bottom of the container whereby electrical signals representing the mass of fluid within the cylinder are created by movement of the diaphragm caused by the mass of fluid thereon. A pressure equalizer which equalizes the pressure within the container to the pressure on the opposite side of the diaphragm allows the measurement of the mass to occur independent of any variations and pressure within the container. Liquid within the mass of liquid within the container can be accurately measured such that a desired mass of liquid may be transmitted for further use. The liquid may be vaporized and transmitted as a vapor.Type: GrantFiled: April 18, 2011Date of Patent: February 24, 2015Assignee: Ceres Technologies, Inc.Inventor: Donald B Rodgers

Patent number: 6588458Abstract: The invention relates to a system, apparatus, and method for measuring and transferring the contents of a vessel. The apparatus includes an outer vessel having a liquid disposed therein and an inner vessel positioned to float in the liquid of the outer vessel. A liquid is also disposed in the inner vessel. An input passageway is associated with the inner vessel and at least one output passageway is associated with the outer vessel. A magnet or other sensed member is positioned on the inner vessel and a sensor, such as a Hall-effect sensor, is associated with the outer vessel. The sensor is configured so as to read the position of the inner vessel relative to the sensor to determine the weight of the inner vessel.Type: GrantFiled: July 6, 2001Date of Patent: July 8, 2003Assignee: Icon Dynamics, LLCInventor: Donald B. Rodgers

Patent number: 6325094Abstract: A bubbler container assembly particularly adapted for use in vapor generating systems comprising a main outer vessel, an inner bubbler vessel, a carrier gas inlet and a vapor outlet such that the inner bubbler vessel is contained within the main outer vessel and the bubbler container assembly is constructed so as to self-meter an incoming supply of vaporizable liquid during the introduction of a carrier gas and extraction of resulting vapor. Preferably, the system further provides for magnetic induced centering and positioning of the inner buoyant bubbler vessel, fluid temperature sensing and control, connection of a fluid makeup supply, carrier gas inlet supply, and vapor extraction outlet.Type: GrantFiled: September 3, 1999Date of Patent: December 4, 2001Assignee: Icon Dynamics, LLCInventor: Donald B.
