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.
