#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).

(b) The instrument also features the ability to adjust the contrast of the display. This is achieved by controlling the “LCD Contrast Adjust” pot.

CALIBRATION PROCEDURE
The meter has been calibrated during manufacture. However, it may be necessary to re-calibrate periodically. Particularly if the instrument is used foe a long period or if the conductivity electrode is changed. To re-calibrate the instrument, follow the procedures shown below : (1) Prepare a ” 1.413 mS Calibration Solution “.
(2) Slide the ” Range Select Switch” to “2 mS” position.
(3) Immerse the ” Conductivity Electrode” into the solution up to the immersion level.
(4) Adjust the ” Calibration Adjust Pot “(VR4, Fig. 2), located within the battery compartment, until the display indicates the value of the calibration solution.

REPLACEMENT OF BATTERY
(1) When the left corner of LCD display show “LBT”, it is necessary to replace the battery. However, in-spec measurement may still be made for several hours after low battery indicator appears before the instrument become inaccurate.
(2) Slide the Battery Cover(3-11, Fig. 1) away from the instrument and remove the battery.
(3) Install a 9V battery(heavy duty type) and replace the cover.
