| Abstract: | Abstract： The importance and existing methods of steam dryness measurement in heavy oil exploitation are introduced and the shortcomings of existing methods are analyzed. The design idea of the optical fiber steam dryness sensor based on infrared absorption difference between steam and liquid water is proposed. The signal acquisition part adopts reflection type structure with double optical-paths. Transmitted through high temperature optical fiber, the modulated signals are demodulated after photoelectric conversion, amplification and software process . In the end, the dryness are displayed and changing curves of dryness are painted . |
