Filed:

Sep 19, 2001

Appl. No.:

09/955765

Inventors:

Robert E. Dutton - Louisville CO
Chad Steele - Denver CO

Assignee:

Micro Motion, Inc. - Boulder CO

International Classification:

G01F 174

US Classification:

73 6144, 7386104

Abstract:

A method and system of performing multiphase flow measurements. The method includes separating an incoming multiphase flow into a majority liquid component and a majority gas component. The majority liquid component comprises a water component and an oil component. The method further includes determining if the majority liquid component includes entrained gas. If the majority liquid component is substantially free from entrained gas, then the method further includes determining a water-cut of the majority liquid component, determining a density of the majority liquid component using a Coriolis flowmeter, and processing the water-cut and the density of the majority liquid component to determine a density of the oil component.

Appl. No.:

10/737856

Inventors:

Robert E. Dutton - Louisville CO, US
Wade M. Mattar - Wrentham MA, US

Assignee:

Invensys Systems, Inc. - Foxboro MA

International Classification:

G01F 1/84

US Classification:

73861354

Abstract:

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.

Appl. No.:

10/542119

Inventors:

Robert E. Dutton - Louisville CO, US
Christopher M. Russell - Cypress TX, US

Assignee:

Micro Motion, Inc. - Boulder CO

International Classification:

E21B 47/10

US Classification:

7315232

Abstract:

A measurement system () is disclosed comprising a Coriolis flow meter () and a control system (). A base fluid () 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 () is then added to the base fluid to create a fracture fluid (). 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.

Appl. No.:

10/430879

Inventors:

Robert E. Dutton - Louisville CO, US

Assignee:

Micro Motion, Inc. - Boulder CO

International Classification:

G01F 1/84

US Classification:

73861356, 73861357, 73861355

Abstract:

A Coriolis flowmeter is operable as a vibrating tube densitometer where a flowtube is driven to vibrate at a fundamental frequency from which density of the material flowing through the flowtube may be calculated. The drive gain is monitored as an indicator of multiphase flow including gas and liquid components where a substantial increase in drive gain indicates gas damping of the flowtube vibrations due to a transient bubble entering the flowtube. The gas damping effects of the transient bubble and the correspondingly reduced density readings are remediated by the use of historical density measurements corresponding to periods of flow when no transient bubble has entered the flowtube.

International Classification:

G01F 1/12
G01F 1/50
G01F 25/00

US Classification:

702100

Abstract:

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.
