Problems solved by technology

[0003] The above technical solutions all clean the ultrasonic reflective sheet without disassembling the ultrasonic flowmeter, but the position or angle of the reflective sheet will change during the process of cleaning the reflective sheet with a motor or cleaning mechanism, which will affect the measurement accuracy.
At present, there is no ultrasonic flowmeter that can effectively correct the state of the ultrasonic reflector after cleaning. Therefore, an ultrasonic flowmeter that can adjust the reflector bracket is proposed.

Abstract

The invention discloses an ultrasonic flowmeter with an adjustable reflector plate bracket, which comprises an ultrasonic flowmeter shell, an ultrasonic transducer, a reflector plate below the ultrasonic transducer and the reflector plate bracket, and is characterized in that the reflector plate bracket is connected with an adjusting device for adjusting the angle and the position of the reflector plate bracket, and the adjusting device adopts an ultrasonic reflector plate abnormity correction algorithm to adjust the reflector plate bracket. According to the method, the problem of how to effectively correct the state of the ultrasonic reflector plate after the ultrasonic flowmeter is cleaned is solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent ultrasonic flowmeters, and in particular relates to an ultrasonic flowmeter with an adjustable reflector bracket. Background technique [0002] Ultrasonic flowmeters need to complete the measurement through ultrasonic emission and reflection. The long-term use of ultrasonic flow sensors and scale on the reflection sheet will seriously affect the measurement accuracy. At present, the technology for cleaning ultrasonic reflectors, such as the Chinese patent "Disassembly-free Cleaning Ultrasonic Meter" with publication number CN102410857A, proposes that the hand-held cleaning machine of the ultrasonic meter is connected with a connecting plug, and the cleaning energy on the hand-held cleaning machine is passed through the connecting plug. The cleaning energy is delivered to cleaning transducers, at least one of which is installed between the metering transducers. The Chinese patent "A Precise Me...
