Detecting liquid in an acoustic flow meter. At least some of the illustrative embodiments are methods including 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.

Abstract:
Flow meter validation techniques are herein disclosed. An illustrative system includes a flow meter and display logic coupled to the flow meter. The flow meter is configured to provide information indicative of a parameter of fluid flow through the meter. The display logic is configured to provide a display of the information. The display includes an indication of a possible range of values of the parameter. An indication of a baseline portion of the range is also provided. The baseline portion of the range designates preferred values of the parameter. The display further includes an indicator designating the value of the parameter.
System And Method Of An Acoustic Flow Meter With Dual Flow Measurements
Acoustic flow meter with dual flow measurements. At least some of the illustrative embodiments are flow meters comprising a spool piece that defines a central passage, a first plurality of transducer pairs mechanically coupled to the spool piece, a second plurality of transducer pairs mechanically coupled to the spool piece, and meter electronics electrically coupled to the first and second plurality of transducer pairs (the meter electronics configured to determine a first value indicative of fluid flow through the central passage, the first value determined using only signals of the first plurality of transducer pairs). The meter electronics further configured to determine a second value indicative of fluid flow through the central passage, the second value determined using only signals of the second plurality of transducer pairs.
Temperature Verification For Ultrasonic Flow Meters
Apparatus and methods for verifying temperature measurements in an ultrasonic flow meter. In one embodiment, an ultrasonic flow metering system includes a passage for fluid flow, a temperature sensor, and an ultrasonic flow meter. The temperature sensor is disposed to measure temperature of fluid flowing in the passage. The ultrasonic flow meter includes a plurality of pairs of ultrasonic transducers and control electronics. Each pair of transducers is configured to form a chordal path across the passage between the transducers. The control electronics are coupled to the ultrasonic transducers. The control electronics are configured to measure speed of sound between each pair of transducers based on ultrasonic signals passing between the transducers of the pair. The control electronics are also configured to determine, based on the measured speeds of sound, whether a measured temperature value provided by the temperature sensor accurately represents temperature of the fluid flowing in the passage.
