摘要：

An ultrasonic acoustic leak detector was designed / manufactured to detect piping leakage. The ultrasonic acoustic leak detector board designed / manufactured in this paper was tested in accordance with the American Society for Testing and Materials ASTM E1002-05 class II. There were 10 ultrasonic leak detector boards designed / manufactured, and 2 outdoor, 1 indoor, and 2 mechanical noise environments were used for the tests. Performance verification tests were conducted in three ways. The intensity of the ultrasonic acoustic signal emitted from a nozzle having a size of 0.2 mm under a gauge pressure of about 70 kPa was measured at a distance of 5 m or more. The result of the experiment and verification is described. © ICROS 2020.
