流量計。 A transparent conduit through which a fluid to be measured flows, a bubble generating means provided on the upstream side of the transparent conduit, and a polygon mirror skim provided on the downstream side of the transparent conduit to reflect a laser beam on a polygon mirror and irradiate the measured fluid. A drive signal for driving the bubble generating means is transmitted, and the bubbles generated in the measurement fluid by the transmission of the drive signal are visualized with a polygon mirror scanner and the profile of the measurement fluid is visualized through a camera. 1. A flowmeter, comprising: a calculation means for detecting the approximate profile, calculating the approximate profile, and using this to calculate the flow rate of the measured fluid.
