#Ultrasonic Leakage detector, GS-5800 #Lutron GS-5800 ULTRASONIC LEAKAGE DETECTOR
THEORY OF ULTRASONIC LEAK DETECTION The human ear can hear sound frequency up to 18 kHz. The sound frequency above 20 kHz is categorized as ultrasonic sound which is not audible. Ultrasonic sound is very directional in nature. We can utilize this nature to pinpoint the exact origin of the sound source &/or where the leak is located. Physics tells us that the gas always flows from the higher pressure region to the lower one. When the pressure difference is only a small opening, the turbulence created by the gas through that small hole then generates an ultrasonic sound.
When any gas flows through a small opening at a rate greater than 10 F-5 atmospheric ml/sec(milliliter per second), the gas is then generally viewed in the viscous flow dominion. As you know, the bigger the pressure difference across an opening, the faster the velocity. As the velocity increases, the frequency of the emitted ultrasonic sound will become higher too. The overall spectra of the emitted ultrasonic sound is generally called “white noise”. The velocity and volume of a leaking gas are affected by the viscosity of the gas. The higher viscosity of the gas, the velocity is slower and the volume is lower through the opening.
Features This ULTRASONIC GAS LEAKAGE DETECTOR is designed to locate the source of the ultrasonic emissions generated by gas or air leaks. The leakage level is displayed by the “Bar LED Display Panel”, and is covered to audible sound by either internal buzzer or to an external earphone (optiona l).
