Ultrasonic water meter


The semiconductor laser ① is focused on the measured object ⑥ by the lens ②. The reflected light is collected by the lens ③ and projected onto the CMOS array ④; The signal processor ⑤ calculates the position of light points on the array ④ through trigonometric function to obtain the distance from the object.
