Gas turbine flowmeter is a gas medium measurement instrument especially common in industrial production, its working principle is: the measured gas entering the flowmeter, accelerated by the deflector frame of cross-section shrinkage, through the inlet channel acting on the turbine blade, driving the impeller rotation. The impeller shaft is installed on the rolling bearing, and the number of impeller revolutions proportional to the volume of the measured gas is transmitted to the counter or flow computer after multiple decelerations to display the volume of the measured gas under actual conditions. In order to keep the instrument in a normal and stable working state, attention should be paid not only to the initial selection, but also to the correct and standardized operation in the subsequent installation and maintenance operations.
