For Difficult Leaks, the Key Is Not Louder Sound — It Is Identifying Leak Noise from Background Noise

Pipeline leak sounds are often masked by traffic, machinery, water flow, and structural noise. GRLE uses an amplifier, filter characteristics, piezoelectric sensor, and noise-reducing headphones to help technicians focus on suspected leak sounds, narrow down the repair area, and reduce misjudgment or unnecessary damage.

Features
Product Features
Built around high-gain amplification, piezoelectric sensing, noise-reducing headphones, and 100Hz–1000Hz filtering, GRLE supports leak sound identification in residential, commercial, and industrial environments.
High-Gain Amplification

56dB ±3% amplifier gain helps amplify weak leak sounds for on-site diagnosis.

100Hz–1000Hz Filtering

Filters the common leak sound frequency range and helps reduce some environmental interference.

Piezoelectric Sensor

Piezoelectric sensing detects vibration and sound from pipe or structural surfaces.

Noise-Reducing Headphones

23dB noise reduction rating helps technicians focus on leak sounds in field environments.

Wide Operating Temperature Range

Operates from -7℃ to 54℃ for most indoor and outdoor inspection conditions.

Complete Carrying Case

Carrying case supports organized storage, transport, and field service use.

Applications
Applications
Suitable for leak detection and acoustic leak location in indoor and outdoor pipelines, concrete slabs, walls, swimming pools, residential properties, commercial buildings, hydrants, and related piping systems.
Indoor and Outdoor Pipeline Inspection

Suitable for identifying leak sounds in residential, commercial, and industrial water pipes.

Concrete Slabs and Walls

Can be used around concrete slabs, walls, and concealed piping areas.

Swimming Pool Leaks

Suitable for detecting suspected leaks in swimming pools and related piping systems.

Hard-to-Locate Leaks

The SAM acoustic manifold helps amplify leak sounds to assist more accurate leak location.

Hydrants and Pipe Equipment

Can be used for leak detection around hydrants, valves, fittings, and water supply pipes.

Residential and Commercial Inspection

Suitable for leak detection service in homes, commercial properties, and maintenance jobsites.
