Abstract: Vibratory meters (5), and methods for their use measuring a fluid are provided. Each vibratory meter includes a multichannel flow tube (300) comprising two or more fluid channels (302), a pickoff (170), a driver (180), and meter electronics (20) configured to apply a drive signal to the driver at a drive frequency ω, and measure a deflection of the multichannel flow tube with the pickoff. In examples, at least one fluid channel has an effective diameter that is related to velocity of sound and drive velocity. In further examples, the driver may apply a drive signal to the driver having a drive frequency proportional to the velocity of sound and effective diameter.

Abstract: A meter electronics (20) for a flowmeter (5) configured to receive a process fluid is provided. The meter electronics (20) includes an interface (201) configured to communicate with a flowmeter assembly of the flowmeter (5) and to receive a vibrational response. The meter electronics (20) comprises a drive gain threshold determination routine (215) configured to determine a first predetermined drive gain threshold (302), monitor a drive gain signal over a predetermined time period, and determine lowest points in the drive gain signal over the predetermined time period. A second drive gain threshold is determined based upon reaching a predetermined number of instances of low points of the drive gain signal.

Abstract: Coriolis direct wellhead measurement devices and methods are provided. The devices and methods allow for continuous monitoring, more frequent data, and greater accuracy in quantitative and qualitative measurements of well performance. In an embodiment: an entrained gas severity of a wellhead is determined based on a determined drive gain threshold, at least one variable is output based on the determined entrained gas severity, and a respective confidence indicator correlating to the at least one variable is output. One mode of operation includes continually averaging the at least one variable over a predetermined time interval and outputting a respective single averaged data value. Another mode of operation includes outputting at least one instantaneous variable at predetermined and uniform time intervals. Diagnostic information and user alerts are also output to provide reliable decision making information to an operator.

Abstract: A vibratory meter (5) including a multi-channel flow tube (130) is provided. The vibratory meter (5) includes a meter electronics (20) and a meter assembly (10) communicatively coupled to the meter electronics (20). The meter assembly (10) includes the multi-channel flow tube (130, 330, 430, 530) comprising two or more fluid channels (132, 332, 432, 532) surrounded by a tube wall (134, 334, 434, 534). The two or more fluid channels (132, 332, 432, 532) and tube wall (134, 334, 434, 534) comprise a single integral structure. A driver (180) is coupled to the multi-channel flow tube (130, 330, 430, 530). The driver (180) is configured to vibrate the multi-channel flow tube (130, 330, 430, 530). The two or more fluid channels (132, 332, 432, 532) and tube wall (134, 334, 434, 534) are configured to deform in the same direction as the single integral structure in response to a drive signal applied to the driver (180).
