Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ultrasonic water meters, in particular to ultrasonic water meter reflector testing equipment. Background Art
[0002] With the continued promotion and application of ultrasonic technology, ultrasonic water meters are gradually replacing traditional mechanical water meters, and demand is growing annually. In U-shaped reflective ultrasonic water meters, the ultrasonic reflector, a key optical component used in velocity calculation and flow measurement, is crucial for these meters.
[0003] Currently, during prolonged use, ultrasonic water meters are subject to the constant impact of water flow, environmental fluctuations, temperature, and pressure, and other factors, which can cause deformation of the ultrasonic reflector's support and bracket. This can even cause deformation of the ultrasonic reflector, causing the reflector's angle to change, affecting the propagation and direction of the ultrasonic wave. This can weaken the receiving end's reception, or even eliminate the ultrasonic wave, affecting metering accuracy. However, because the reflector is fixed in the pipe and difficult to remove, determining whether the reflector's angle has changed is difficult. Furthermore, different ultrasonic water meters come in different sizes and lengths, making it difficult to adjust the laser emitter and camera positions during testing, which presents challenges.
