| Abstract: | Measuring the gas pipeline in the artificial flow by using pitot tube is high accuracy，applicability，and economically viable. To promote the application of pitot tube in the mine gas extraction measurement，according to the principle of pitot tube，this paper introduced the method of pitot tube used in gas extraction measurement. In view of the main influencing factors of the pitot tube measurement，the corresponding optimization measures were proposed from three respects，including improving the precision of equipment，
standardizing the operation of pitot tube，and the simplification for the method of calculation and measurement. |
