Abstract

PURPOSE: To perform dynamic pressure comparing type isokinetic suction and achieve the improvement in accuracy by alternately changing over the Pitot tube differential pressure by the velocity of flow of exhaust gas and the ventury tube differential pressure by the velocity of flow of suction gas with a solenoid valve by the command signal of a time sequence circuit and changing these to electrical signals with one differential pressure detector.
