Laser positioning ultrasonic flow sensor

The utility model belongs to the field of engineering detection, and particularly relates to a laser positioning ultrasonic flow sensor which comprises a shell, an ultrasonic flow sensor arranged in the shell and a laser positioning device. The ultrasonic flow sensor comprises an ultrasonic flow sensor body and an acoustic wedge; the laser positioning device comprises a laser positioning body and a laser diode; the bottom of the shell is provided with a sound wedge opening for accommodating the sound wedge; the side wall of the shell is provided with a laser opening for accommodating a laser diode; the laser diode is vertical to the acoustic wedge; fixed magnets are symmetrically arranged on the front side and the rear side of the acoustic wedge on the shell. According to the ultrasonic flow sensor, the laser positioning device is integrated on a traditional ultrasonic flow sensor, the whole device is installed on a to-be-measured pipeline through the fixed magnet on the lower portion of the shell, the two se
