Find leaks quickly with ultrasound technology! Ultrasound leak detection covers pressure or vacuum leaks of any kind, liquid or gas. Ultrasound instruments detect turbulent flow produced as the fluid (liquid or gas) moves from the high-pressure side to the low-pressure side of the leak. Ultrasound leak inspection is especially beneficial in areas where there is a saturation of gases, or where a wide variety of pressurized vessels and vacuum processes are located. Ultrasound leak detection is used in many facilities for safety, energy, environmental, and quality assurance reasons.
