A new method is proposed for measuring the pulsating flow rate. Under pulsating conditions the output of conventional differential pressure flowmeters contains the acceleration term due to the fluid inertia, which causes a pulsation error in the measurement of the flow rate. In the proposed method, the stream to be measured is divided into two branch streams and each stream is constricted by the converging section of each branch channel. The pressure difference between the two channels is detected by a manometer at a point where the acceleration term of each stream cancels out. The instantaneous flow rate can then be obtained from the output of the manometer without being affected by the acceleration term. An experimental apparatus was built, and several experiments for air flow were performed with this apparatus. The results indicate that the proposed flowmeter is capable of measuring the instantaneous flow rate in the pulsating regime.
