Description

technical field [0001] The invention relates to an optical element measuring device, in particular to a micro-angle change measuring device for an ultrasonic water meter reflector. Background technique [0002] With the continuous promotion and application of ultrasonic technology, ultrasonic water meters are gradually replacing traditional mechanical water meters, and the demand is also increasing year by year. In the U-shaped reflective ultrasonic water meter, the ultrasonic reflective sheet is an important optical structure in the speed calculation and flow measurement of the ultrasonic water meter. Its importance is crucial for the U-shaped reflective ultrasonic water meter. [0003] At present, during the long-term use of ultrasonic water meters, due to the continuous impact of water flow, the influence of environment, temperature, pressure changes and other factors, the ultrasonic reflective sheet pillars, brackets, etc. will be deformed, and even the ultrasonic reflec...

Problems solved by technology

[0003] At present, during the long-term use of ultrasonic water meters, due to the continuous impact of water flow, the influence of environment, temperature, pressure changes and other factors, the ultrasonic reflective sheet pillars, brackets, etc. will be deformed, and even the ultrasonic reflective sheet will be deformed, resulting in ultrasonic Changes in the angle of the reflector will affect the propagation of ultrasonic waves, which will lead to changes in the direction of ultrasonic wave propagation, weaken the receiving end's receiving strength, or even fail to receive ultrasonic waves, which will affect the measurement accuracy

However, since the reflector is fixed in the pipeline and is not easy to disassemble, it is difficult to identify whether the angle of the reflector changes. Therefore, a convenient and easy-to-operate ultrasonic water meter reflector micro-angle change measurement device is particularly important.
