omega0615The Omega HHLT-1R amplifies and converts ultrasonic sounds to frequencies and levels that the human ear can hear. Ultrasonic sound (20 to 100 kHz) is generated by turbulence created by air or a gas forced through a small orifice. Ultrasonic sound is very directional in nature and can be used to pinpoint the exact location of the leak point. Leaking air or gas is generally considered to be viscous flow and as the flow velocity increases, the frequency of the ultrasonic sound emitted will become higher. The HHLT-1T transmitter supplies ultrasonic signals for locations where the gas/air leak does not have sufficient pressure to create an ultrasonic sound.
