1. A system for measuring flow rates for effluents of individual petroleum wells in a well pad, comprising:
a multiphase flowmeter comprising a pressure sensor; a valve assembly connected between each of the individual petroleum wells and the multiphase flowmeter, the valve assembly configured to connect and disconnect an effluent from a single selected individual petroleum well to the multiphase flowmeter; and means for performing custom-calibration of said pressure sensor for each individual petroleum well to enhance the accuracy of resulting flow rate measurements, wherein said custom-calibration means include a digital controller operably connected to the pressure sensor and the valve assembly, wherein the digital controller configured to determines a pressure drop range for each of the individual petroleum wells in the well pad, to selects and individual petroleum well for flow rate measurement, and to calibrates the flow meter with the pre-determined pressure drop range corresponding to the selected individual petroleum well.
