Abstract
PURPOSE:To measure a flow rate without being affected by a disturbance of a flow velocity distribution, by measuring flow velocity at several points on a straight line crossing a flow to determine a flow rate based on an average flow velocity determined from the flow velocity distribution obtained. CONSTITUTION:A first vibrator 1 and seven second vibrators 2a-2g are mounted on the outer wall side of an upright tube section A provided in the course of a flow. The first vibrator 1 and the second vibrators 2a-2g are arranged at a position symmetrical to the center axis of the upright tube section A. The second vibrators 2a-2g as receiving vibrator are arranged on extensions of seven parallel lines Y1-Y7 crossing a straight line T at flow velocity measuring points a3-a-3. Thus, flow velocity is measured by a Doppler method at these several flow velocity measuring points to obtain a flow rate based on an average flow velocity determined from a velocity distribution of flow obtained from the resulting flow rate values.
