Coriolis direct wellhead measurement apparatus and method

The invention relates to a Coriolis direct wellhead measurement apparatus and method. Apparatus and methods allow for continuous monitoring, higher frequency data, and higher accuracy in quantitative and qualitative measurements of well performance. In an embodiment, an entrained gas severity of the well 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 associated with the at least one variable is output. One mode of operation includes continuously averaging 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. 本申请涉及科里奥利直接井口测量设备和方法。设备和方法虑及连续监测、更高频率的数据和在井性能的定量和定性测量方面的更高准确度。在实施例中：基于所确定的驱
