Question

Which of the following leak detection methods is considered to be the most effective for locating the general area of a small leak?

1) Standing vacuum test
2) Electronic or ultrasonic tester
3) Halide torch
4) Audible sound

Answer 1

The most effective leak detection method for locating the general area of a small leak is the Electronic or ultrasonic tester. This method uses high-frequency sound waves to detect the change in sound frequency caused by the escaping gas or liquid.

Step-by-step explanation:

The most effective leak detection method for locating the general area of a small leak is the Electronic or ultrasonic tester. This method uses high-frequency sound waves that are emitted by the tester and then detected by receivers. These sound waves can easily locate the general area of a leak by detecting the change in sound frequency caused by the escaping gas or liquid.

For example, a small leak in a pressurized pipe would cause the ultrasonic tester to detect a higher frequency sound in the area of the leak. This method is considered highly accurate and efficient in locating small leaks.
