The invention relates to the technical field of air volume measuring devices, in particular to a multi-point air volume measuring device. The rolling ball connected in the support mechanism in a rolling mode is matched with the threaded rod which penetrates through the rolling ball and is in threaded connection with the rolling ball to form a seesaw effect, the position of the rolling ball is adjusted through threads to achieve balance of the two sides, and the air inlet pipe assembly and the leeward pipe assembly which are arranged at the two ends of the threaded rod keep balance on the threaded rod. The umbrella-shaped adjusting assembly arranged on the leeward pipe assembly gradually rotates to the position with the uniform pressure due to uneven surface pressure when the air flow track changes, and therefore balance can be kept when the rolling ball rotates to any position. Therefore, the leeward pipe assembly and the air inlet pipe assembly are driven to correspondingly rotate to the position where the c
