[0001] This utility model relates to the field of ultrasonic flow meter technology, and in particular to an ultrasonic flow meter for flow detection. Background Technology

[0002] An ultrasonic flow meter is a non-contact instrument that can measure the flow rate of media in large-diameter pipes as well as media that are difficult to access and observe. It has high measurement accuracy, with clamp-on installations achieving an accuracy of up to ±0.5%. It is almost unaffected by various parameters of the measured medium and can especially solve the problem of measuring the flow rate of highly corrosive, non-conductive, radioactive, and flammable and explosive media that other instruments cannot.

[0003] Since transducers are prone to aging and have their service life affected by high temperature and high pressure environments, and their transmission and reception efficiency is easily affected, a new solution is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an ultrasonic flow meter for flow detection. The meter monitors the temperature using an infrared monitoring probe of a rotatable temperature sensor mounted on a clamping plate. When the temperature exceeds the optimal operating temperature, manual intervention can be performed to extend its service life.

[0008] By adopting the above technical solution, the angle of the temperature sensor can be adjusted by connecting the universal ball seat fixed on the connecting rod and the movable seat set at the bottom of the bracket, thus adapting to multi-angle monitoring.
