Publication number: 20080115561Abstract: Descriptions are provided for implementing flowmeter zero checking techniques. In operating a flowmeter, it may be the case that, even if previously calibrated, the flowmeter will produce erroneous measurements, e.g., will indicate a non-zero flow during a period of zero flow. Therefore, zero checking features are provided that allow for fast and accurate determinations of the zero-flow values, for use in adjusting later measurements. The zero-checking features include a button attached to an exterior of a flowmeter, so that it is easily accessible to an operator of the flowmeter. The button, in conjunction with an internal zero checking system, allows for a display of a zero value in response to a request from the operator of the flowmeter.Type: ApplicationFiled: January 18, 2008Publication date: May 22, 2008Applicant: Invensys Systems, Inc.Inventor: Robert Dutton

Publication number: 20080034892Abstract: A flowmeter is disclosed. The flowmeter includes a vibratable flowtube, and a driver connected to the flowtube that is operable to impart motion to the flowtube. A sensor is connected to the flowtube and is operable to sense the motion of the flowtube and generate a sensor signal. A controller is connected to receive the sensor signal. The controller is operable to determine an individual flow rate of each phase within a multi-phase flow through the flowtube.Type: ApplicationFiled: March 5, 2007Publication date: February 14, 2008Applicant: Invensys Systems, Inc.Inventors: Michael Tombs, Manus Henry, Mihaela Duta, Robbie Lansangan, Robert Dutton, Wade Mattar

Publication number: 20060144136Abstract: A measurement system (200) is disclosed comprising a Coriolis flow meter (222) and a control system (224). A base fluid (250) is first flowed through the Coriolis flow meter. The Coriolis flow meter measures a density of the base fluid and transmits a base fluid density measurement to the control system. A proppant (252) is then added to the base fluid to create a fracture fluid (202). The fracture fluid is then flowed through the Coriolis flow meter. The Coriolis flow meter measures a density of the fracture fluid and transmits a fracture fluid density measurement to the control system. The control system determines an amount of proppant in the fracture fluid based on the base fluid density measurement, the fracture fluid density measurement, and a density of the proppant.Type: ApplicationFiled: February 5, 2003Publication date: July 6, 2006Inventors: Robert Dutton, Christopher Russell

Publication number: 20060123923Abstract: A steam measurement system includes a Coriolis flowmeter associated with a vibratable flowtube to receive a flow of wet steam. A first sensor is associated with the flowtube to relay information about a motion of the flowtube by way of a first sensor signal. A second sensor determines a property of the flow and relays the property by way of a second sensor signal. A computing device receives the first and second sensor signals and is configured to calculate a steam quality of the flow from the first and second sensor signals. The computing device also may calculate the total heat energy flow rate of the flow. Other implementations may include a full or partial separator to separate the flow of wet steam into a substantially gas flow and a substantially liquid flow and a second Coriolis meter.Type: ApplicationFiled: February 1, 2006Publication date: June 15, 2006Inventors: Robert Dutton, Wade Mattar

Patent number: 4581373Abstract: A derivative of a biologically active substituted tin compound with a lipophilic strong acid containing sulphur or phosphorus, or a salt thereof. These derivatives are readily soluble in organic liquids and are thus readily formulated as emulsifiable concentrates.Type: GrantFiled: January 19, 1983Date of Patent: April 8, 1986Assignee: The Dow Chemical CompanyInventors: Patrick J. Mulqueen, Robert Dutton

Patent number: 3997872Abstract: When two asynchronous signals may occur at approximately the same time, only one of the signals being able to control consequent events, a circuit accounts for the conflict situation by selectively adding a delay until the conflict situation has settled. While the circuit does not determine which asynchronous event may control, the selective delay extends the time for the decision to be made. This circuit provides high reliability while minimizing delays and eliminates the need for indiscriminately adding a delay to each asynchronous event so as to resolve conflict situations. The circuit has particular applicability to volatile memory systems wherein conflict between processor requests and refresh requests to memory occur and allows processor requests to proceed with minimum delay in nearly all situations.Type: GrantFiled: July 14, 1975Date of Patent: December 14, 1976Assignee: Digital Equipment CorporationInventors: David Andrew Cane, David Robert Dutton, John M.
