This paper is pneumatic differential pressure principle of work, the mercury column measuring instrument of performance, appli-cation research. In the pneumatic pressure difference sensor measuring instrument, the mercury column pneumatic measuring instrument us-ing gas pressure constant, through the throttle nozzle, when the throttle nozzle and the measured gap between the workpiece increases caused by the increased flow, then between the throttle nozzle and nozzle pressure drop, change through a sensitive mercury column manom-eter indicates that the dimension of workpiece.
