Patent number: 6745135Abstract: A system, method, and software are disclosed that determine a proportion of a majority component of a fluid that is flowing through a Coriolis flowmeter. Circuitry receives pickoff signals and a temperature signal from the Coriolis flowmeter responsive to the fluid being flowed through the Coriolis flowmeter. The circuitry processes the pickoff signals and the temperature signal to determine a proportion of the majority component relative to the fluid. To determine the proportion of the majority component in one example, the circuitry determines a first volumetric flow rate based on a measured mass flow rate of the fluid and a reference density of the majority component. The circuitry then determines a second volumetric flow rate based on a measured volumetric flow rate, a temperature-varying density, and the reference density. The circuitry determines the proportion of the majority component based on the first volumetric flow rate and the second volumetric flow rate.Type: GrantFiled: April 21, 2003Date of Patent: June 1, 2004Assignee: Micro Motion, Inc.Inventors: Michael J.

Patent number: 6612186Abstract: An energy metering device includes a volumetric flow meter or mass flow meter in combination with a gas analyzer that provides telemetry regarding the constituents of a natural gas flow stream. An interpreter analyzes this information and provides a real time output corresponding to the enthalpy of combustion for the gas stream. This output is used to adjust or throttle the gas flow stream for purposes of delivering the flow stream according to a preselected parameter, which is related to desired operating conditions for a combustion device including a boiler or an engine.Type: GrantFiled: February 16, 2000Date of Patent: September 2, 2003Assignee: Micro Motion, Inc.Inventors: Andrew T.

Patent number: 6556931Abstract: An apparatus and method for determining a density compensated flow rate of a material flowing through a vibrating conduit. Signals are received from sensors affixed to the vibrating conduit. An uncompensated flow rate of said material is then calculated from the signals. A density compensation factor is then determined from the uncompensated flow rate and non-linear information relating density to errors in flow rate. The density compensated flow rate is then determined by applying the density compensation factor to the uncompensated flow rate.Type: GrantFiled: November 3, 2000Date of Patent: April 29, 2003Assignee: Micro Motion, Inc.Inventors: Paul J.

Patent number: 6092409Abstract: A System for validating a flow calibration factor for a Coriolis flow meter. In accordance with the present invention, the period of oscillation of a flow tube is measured as a material of a known density flow through the flow tube. The period of oscillation is used in an equation derived from an equation used to calculate the density of material flowing through the flow tube to find a result. The result is then compared to a result derived from the known density of the material to detect a possible error condition in the flow tube. If an error condition exists an error signal is generated that indicates the Coriolis flow meter should be inspected.Type: GrantFiled: January 29, 1998Date of Patent: July 25, 2000Assignee: Micro Motion, Inc.Inventors: Andrew T.

Patent number: 5497666Abstract: An increased sensitivity Coriolis flowmeter having one or more drivers oscillates a flow tube, or tubes, at pre-determined frequencies thereby producing active and/or static nodes at points along the flowtube(s). The increased sensitivity of the present flowmeter is provided by controllably locating sensors in close proximity to the static nodes and/or active nodes. In a first embodiment, the flowtubes are oscillated in a manner generating a single active node with sensors positioned in close proximity to, and on opposing sides of, the active node. In a second embodiment, the flowtubes are oscillated in a manner generating multiple active nodes where the sensors are located on opposing sides of each active node, or on opposing flowtubes where one sensor is above an active node on one leg and a second sensor below the active node on the opposing leg. In another embodiment, sensors are positioned in close proximity to static nodes in addition to the sensor positions for active nodes as previously stated.Type: GrantFiled: July 20, 1994Date of Patent: March 12, 1996Assignee: Micro Motion, Inc.Inventors: Andrew T.
