Digital Acoustic Leak Locator

 

The Aquascope-3 acoustic leak locator offers new levels of confidence in ground-mike leak sounding with innovative digital sound analysis and visualisation of the leak noise.

AQUASCOPE-3 — Digital Ground Microphone & Listening Stick

The digital Aquascope-3 can be supplied as a listening stick (for listening to leak noise activity from direct contact onto the pipe, valves or fittings) and tripod foot for surface listening on loose/uneven ground.

 

Alternatively, it can be supplied with a shrouded geophone foot (ground microphone) for improved sound monitoring above the suspected leak position.

 

By listening at regular intervals (above ground) along the line of the pipeline being surveyed, the user is able to identify both audibly (via the headphones) and visibly (from an integral display) where the strongest leak noise activity is located.

Features:

 

· Digital leak noise analysis displays real leak noise level

· Automatic memorisation of leak noise levels for comparison

· Ergonomic amplifier with comfortable waist belt – avoids neck strain

· High performance sensor developed for correlation technology

· Infinitely adjustable, narrow band-pass filter to suppress ambient noise

· Graphical and digital leak information on LCD display with backlight

· Robust Ground-Mike with wind-and-ambient sound proofing

· Hand-probe for direct ‘contact sounding’ on pipes and fittings

· Tri-pod foot for ‘surface sounding’ on soft ground

· Robust, field-proof design

· Extremely easy to use

Aquascope listening stick being used for 'contact leak sounding'

The AQUASCOPE-3 automatically samples and records the lowest noise level during the listening session, indicating the true leak noise without ambient interference. The exact value is shown on the LCD display in digital format, plus a visual graph of the actual noise level.

Digital leak noise analysis displays real leak noise level

The true leak noise level is automatically memorised during ‘sounding’. The operator can display and compare the last 8 leak noise levels for a greater level of confidence in achieving precise location or confirmation of the leak position.

Automatic memorization of leak noise levels for comparison

Although the AQUASCOPE-3 amplifier is extremely lightweight at 0.27 kg) it is ergonomically designed with a 'universal band', which can also be worn as a waistband or shoulder strap to avoid neck strain often related with more conventional acoustic locator amplifiers. The amplifier offers easy operation and a clear display of leak information on the backlit LCD display.

Universal amplifier belt offers superior user-comfort

The infinitely adjustable narrow band-pass filter allows the operator to suppress any unwanted interference and background noise, and to reduce the audible range to the exact leak noise frequency.

Narrow band-pass filter suppresses interference and ambient noises

The microphone ‘foot’ is robust, weather proof and acoustically shielded against non-leak interference. It incorporates the same high performance sensor especially developed for leak noise correlator technology.

Shielded, robust ground microphone with high performance sensor

The hand-probe incorporates a handle and the same high performance sensor as the microphone foot. It allows direct listening on fittings, includes 3 extension rods to adapt to on-site conditions, and is delivered together with a magnetically attachable tripod foot, allowing leak location on soft ground.

Versatile hand-probe for direct ‘sounding’ and leak location on soft ground

Special attention has been paid to extremely simple operation in spite of its powerful built-in features, rendering the AQUASCOPE-3 the perfect leak locating tool for any field operator, irrespective of his level of leak detection experience.
