System and methods for analyzing a multiphase production fluid include a fluidic supply and analysis unit configured to transition the fluidic separation chamber to a static state after a complete gaseous phase column and a complete oil phase column are formed within the fluidic separation chamber; communicate with the fluidic separation detector to measure the absolute or relative sizes of the complete gaseous phase column and the complete oil phase column; and calculate an oil/gas volume fraction as a function of the measured sizes of the gaseous phase and oil phase columns in the fluidic separation chamber.

System and methods for analyzing a multiphase production fluid, calculating production fluid phase flow rates, and calculating an oil/gas and oil/gas/water volume fractions of the multiphase production fluid, are provided. Contemplated systems and method may utilize fluidic piping, a production fluid supply valve, a fluidic separation chamber, an inert gas exhaust valve, a separation chamber pressure sensor, a fluidic separation detector, and a fluidic supply and analysis unit.

A gas blending apparatus and an ambient pressure gas delivery and conservation system with such a gas blending apparatus for delivering gas at ambient pressure from a donor reservoir to a recipient. A main conduit body has a first port in fluidic communication with the donor reservoir and a second port for supplying gas to the recipient through ambient pressure tubing. A one-way inspiratory valve between the first port and the second port permits gas to be drawn from the reservoir but not to be received through the second port, through the first port, and into the donor reservoir. An air-input orifice permits ambient air to be blended with gas drawn from the reservoir. An orifice adjustment member is selectively repositionable relative to the air-input orifice to adjust the effective size of the aperture thereby to adjust the ratio of ambient air to gas drawn from the reservoir.
