Influence of liquid level height on ultrasonic detection of water immersion

The influence of liquid level height on ultrasonic detection of water immersion directly affects the detection sensitivity and defect detection rate. According to relevant data, the thickness of water layer directly affects the detection sensitivity and defect detection rate in water immersion ultrasonic testing. In practical application, the installation error of scanning device will lead to the deviation of water layer thickness. By measuring the probe detection sensitivity under different water thickness, the influence law of water thickness deviation on detection sensitivity is obtained.
