20100217531, Aug 26, 2010

Filed:

Feb 26, 2009

Appl. No.:

12/393129

Inventors:

Donald M. Day - Cypress TX, US

Assignee:

DANIEL MEASUREMENT AND CONTROL, INC. - Houston TX

International Classification:

G01V 1/40

US Classification:

702 13

Abstract:

Hydrocarbon measurement station preventative maintenance interval determination. At least some of the illustrative embodiments are measurement stations configured to measure volumetric flow of hydrocarbons, where the measurement stations include a flow meter fluidly coupled to a piping system configured to carry at least one type of hydrocarbon flow, and a computer system comprising an interface device (the computer system electrically coupled to the flow meter and the computer system configured to maintain a plurality of parameters related to the volume of hydrocarbon flow in the piping). The computer system is configured to provide maintenance information for the measurement station, and the computer system provides the maintenance information at intervals determined based on constituents of hydrocarbons and based on parameters related to the volume of hydrocarbon flow in the piping.

Inventors:

Donald Merlyn Day - Cypress TX, US

Assignee:

Daniel Measurement and Control, Inc. - Houston TX

International Classification:

G01F 1/684

US Classification:

7320422

Abstract:

A flow meter and a temperature stabilizing cover for tie flow meter are disclosed. In some embodiments, the flow meter includes a spool member having a throughbore for fluids to pass therethrough, one or more transducers extending into the throughbore, and a cover disposed about the spool member and the one or more transducers. The cover includes a plurality of cover pieces fastened together. The cover pieces are formed of layers including an insulation layer, a radiant barrier, and an outer shell. The outer shell includes a material having a rigidity exceeding that of the insulation layer and that of the radiant barrier.

DANIEL MEASUREMENT AND CONTROL, INC. - Houston TX

International Classification:

G01F 1/28

US Classification:

7386171

Abstract:

Apparatus and methods for proving a flow meter at low temperatures. A flow meter measuring low temperature fluids (e.g., less than about −50 F., or less than about −220 F.) must still be proved. Low temperature fluids can be destructive to piston or compact provers, or may require indirect proving methods. The apparatus disclosed is a low temperature prover directly coupled into the pipeline carrying the low temperature fluids. In some embodiments, a magnetic pickup coil and a magnetic member communicate between the displacer and the flow tube. The magnetic target member may be carbon-free. In some embodiments, a pair of ultrasonic transceivers coupled to the flow tube communicate a signal across the flow tube and a displacer is moveable to interrupt the signal. In some embodiments, the flow tube includes an inner surface having a microfinish for lubrication. The displacer may be a piston rotatable while being moved axially.

Inventors:

Donald Day - Cypress TX, US

Assignee:

Daniel Measurement and Control, Inc. - Houston TX

International Classification:

G08B 21/00
G01F 1/66

US Classification:

340606, 702 48

Abstract:

A method for audibly detecting a fluid flow state change in a flow meter pipeline. The flow state change may be identified as an upset in the normal flow state. The upset may be corrected to improve the accuracy of the flow meter. A system includes acoustic sensors mounted in the flow meter pipeline, and a computer to collect audible data from the acoustic sensors and compare the audible data to a baseline to detect an upset in the normal fluid flow state.

US Classification:

702100, 73 116

Abstract:

A flow meter prover () is provided with multiple pairs of detectors to record multiple calibrated prover volumes with a single pass of the displacer . The prover conduit may be fitted with a first pair of detectors () for a first calibrated prover volume (V) and a second pair of detectors () for a second calibrated prover volume (V). A single pass of the displacer may trip more pairs of detectors () corresponding to more calibrated prover volumes (V, V, V). A flow computer may be configured to record more than two calibrated prover volumes (V, V, V, V) using only two pairs of detectors () and a displacer ().
