Abstract
A method for determining the quality of steam flowing in a line used for steam injection, e.g. in an oil well. It has a vertical loop in the line, with an orifice in the up-flow side. The pressure, temperature and pressure drop at the orifice are measured before and after injecting a stream of water upstream from the orifice. The water stream is injected at a constant flow rate, and its temperature and pressure are measured. Using the measurements before and after the introduction of the water stream, simultaneous equations are developed related to the mass flow rate and to the heat flow rate, so that the steam quality may be determined.
