How does it work? The sensor ultrasonically recognizes the attenuation and dielectric properties of the liquid or air present. Digital sampling insures precise interpretation. The resulting output signal identifies the condition sensed. (read more)

U.E. Systems, Inc.'s patented Liquid Leak Amplifier method (LLA), used in conjunction with any Ultrasonic Inspection System, is ideal for detecting extremely low-level pressure or vacuum leaks that produce minimal or no turbulence by enabling ultrasonic detectors to sense the sound of small bubbles bursting.
