A leak detector that is ultrasonic makes use of sound to detect leaks. Leaks generate a high-frequency sound that can be detected by using an ultrasonic leak detector. The sound source and leak is recorded in an electronic meter, which gives information on the speed of leak as well as the location of the leak.
Utilizing ultrasonic sensors for detection of leaks is a new technology and widely used for investigation of gas leaks. They are perfect to detect leaks that generate sound that is outside of the human hearing range. The device's mechanism reduces the range of sound so that it is heard.

While a leak detector made of helium employs helium gas for examining closed systems by releasing helium inside the system, and then using it to gauge leakage. Helium contains extremely small molecules that allow it to rapidly determine the location of leaks effectively and reliably. Because it is inert and non-toxic, it's an extremely safe and reliable method of testing for leaks as it doesn't interact with chemicals in the system.
A leak detector made of helium, often referred to as the mass spectrometer leak detection (MSLD) is a device that detects and determines leaks using the gas helium as a tracer. The gas enters the device at pressure, and the pressure is then assessed to determine the presence of leaks.
The usage of leak detectors made from helium is a part of pressure and vacuum testing. The vacuum method is where an extrication pump is utilized to remove the system that is to be tested and helium is used to find the source of leakage. The pressure system is used to ensure that the component to be tested is put under pressure using the helium.
