Patent number: 9046400Abstract: A control and measurement system for a coriolis flowmeter having a flowtube, a driver adapted to vibrate the flowtube, and a pair of sensors adapted to generate signals indicative of movement of the flowtube when it is being vibrated by the driver, wherein the sensors are positioned relative to one another so the signals from the sensors are indicative of a mass flow rate of fluid through the flowtube. A digital drive signal generator is adapted to generate a variable digital drive signal for controlling operation of the driver. The digital drive signal generator can be adapted to cause the driver to resist motion of the flowtube during a first time period and amplify motion of the flowtube during a second time period. The digital drive signal generator can also be adapted to initiate motion of the flowtube by sending one or more square wave signals to the driver.Type: GrantFiled: March 29, 2013Date of Patent: June 2, 2015Assignee: Invensys Systems, Inc.Inventors: Manus P.

Patent number: 9037422Abstract: A method for detecting a leak in a fluid conducting conduit is disclosed. Inlet and outlet flowrates are measured for calculating a time derivative of average temperature of the fluid flowing in the fluid conducting conduit. A predicted difference in flowrate between a flowrate of fluid in the fluid conducting conduit adjacent the inlet and a flowrate of fluid in the fluid conducting conduit adjacent the outlet is calculated based on the calculated time derivative of the average temperature of the fluid flowing in the fluid conducting conduit. The predicted difference in flowrate is compared to a difference between the measured inlet flowrate and the measured outlet flowrate to determine whether a leak exists in the fluid conducting conduit.Type: GrantFiled: August 13, 2012Date of Patent: May 19, 2015Assignee: Invensys Systems, Inc.Inventors: Robert Terrence McHugh, Errol F.

Patent number: 9026413Abstract: A method of modeling phase characteristics of thermodynamic systems utilizing pseudo-properties strategy and a reduced number of variables is disclosed herein. The method describes a means of determining the probability of phase splitting of mixtures of materials at a given temperature, pressure, and composition by characterizing the functions that describe the system via pseudo-properties, and also by describing the system in n?1 or fewer variables, where n represents the number of components in the system of interest. In an embodiment, a multi-component system is characterized in one variable, thereby providing simplified thermodynamic models in a time-efficient manner. In addition, the information generated by this reduced-variable calculation can further be used as a starting point for calculations of equations of state.Type: GrantFiled: September 20, 2012Date of Patent: May 5, 2015Assignee: Invensys Systems, Inc.Inventors: Gang Xu, David Bluck
