Experimental Study on Double-Piston Gas Prover

Article Preview

Abstract:

Existing piston gas provers use a single piston cylinder as standard which replace the standard flow of gas by the piston moving at a constant speed. In order to solve the problem that the piston proverflow ceiling is limited by the volume of piston cylinder, we have developed a double-piston gas prover. Firstly, the article introduces the devices principle and mathematical model simply. Then it presents a series of experiments and experiments results of the device. Finally,the paper analyzes the uncertainty of the equipment. The results show that the double-piston gas prover is available.
