Abstract
A flow meter using digital signals constructed in a small size and outputting an electric signal of a position of a float in a tapered tube with high accuracy is provided. A first reflecting meanshas a rayentered from the entering meansand reflected, and a second reflecting meansreflecting the rayreflected from the first reflecting meanstoward the first reflecting meansat least once. An emitting meanshas the rayentered and emits it, and an image sensorhas the rayfrom the emitting meansentered and outputs an image of the floatin the tapered tube, while a control portion executes input processing of an image and outputs an electric signal Sindicating the flow rate of a fluidby detecting the position of the float
