摘要： Detecting liquid in an acoustic flow meter. At least some of the illustrative embodiments are methods comprising flowing a gaseous substance through a central passage of a meter body, sending acoustic signals along respective chordal pathways across the central passage (none of the chordal pathways intersect a lower portion of the central passage where liquid, if present during flow of the gaseous substance, accumulates), calculating a flow velocity of the gaseous substance proximate to each chordal pathway based on transit times of the acoustic signals along the respective chordal pathways, and determining the presence of a liquid accumulated in the lower portion based on the flow velocity proximate to each chordal pathway.

摘要： A method and ultrasonic meter system for determining pipe roughness. At least some of the illustrative embodiments are ultrasonic meters comprising a spool piece, and a first transducer pair mechanically mounted to the spool piece. The ultrasonic meter is configured to determine diagnostic data based on acoustic signals transmitted between the first transducer pair. The ultrasonic meter is configured to determine changes in the roughness of a pipe mechanically coupled to the ultrasonic meter based on a trend of the diagnostic data (wherein the trend comprises a substantially constant value of about unity for both asymmetry and cross flow and a substantially changing value for profile factor).

摘要： A device and method for securing an orifice flowmeter and preventing unauthorized access to the flowmeter while in service is disclosed. The security device includes a housing having a top surface, a bottom surface, a closed end, an open end, a front surface, and a back surface forming a cavity. Through bores extend coaxially through the top surface and the bottom surface proximate the open end. Some embodiments include protrusions coupled to the interior of cavity. The protrusions together with the back surface of the housing are configured to surround exposed portions of the flowmeter, such that the addition of a shackle portion of a locking device through the through bores will prevent removal of the security device from the flowmeter and subsequently prevent access to the flowmeter.

摘要： 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.
