A most effective method of heavy oil production throughout the world now is thermal production through steam injection.During thermal recovery,to get full parameters as to guide production needs a test meter which could be used under high temperature ,high pressure,and steam water biphase conditions.Through investigation of present situation at home and abroad,there is no thermal recovery test meter which could test temperature,pressure,steam flow rate and mass dryness fraction in the same time.To change this situation,this paper proposes the idea of developing an four parameter test meter.Based on existing technique and products at home ,if studying as an item,field probation may be achieved within two or three years.

Conclusion This well head steam quality sampling unit works with minor measurement error. It is cheap, easy installed and technically feasible. Through optimizing the insulating condition, heat loss and quality loss of steam were reduced during pipeline delivery, each target of "eight-nine-eight-seven" system engineering set by CNPC had been attained.
