Gas Flow Measurement Method with Temperature Compensation for a Quasi-Isothermal Cavity

Pneumatic transmission is a technology that uses compressed air as power source to drive and control various mechanical equipment realize the mechanization automation of production processes. With development industrial automation, pneumatic technology, represented by muscle, increasingly becoming more widely used in fields. The current standards for research are complex measurement flow without flowmeter, some them do not consider influence temperature change on measurement, simplified adiabatic or isothermal models, which inaccurate methods actual practical application. This paper describes method determine rate measuring pressure process gas tank inflation. study compensation eliminate formula. structure was simple calculation accurate, has certain significance. Based this method, charging experiments were carried out with had volume 3 L 5 copper wire filling, experimental results processed research. parameters identified an environment different sizes tanks. tank. Finally, completed filled wire. After verification, quasi-isothermal formula close those measured high-precision sensor experiment. introduced novel accurate compared conventional method; furthermore, it can be real world situations need sensor.
