Gutermann AQUASCAN TM2 Leak Detector

Description

Gutermann AQUASCAN TM2 Leak Detector – High-Performance Trunk Main and Long-Distance Water Leak Detection Correlator

The Gutermann AQUASCAN TM2 Leak Detector is a high-performance acoustic leak noise correlator specifically designed for locating difficult water leaks on large-diameter trunk mains, plastic pipes, and long-distance pipelines. It uses highly sensitive wireless stainless-steel accelerometer sensors, advanced signal processing, and automatic filtering to identify weak and low-frequency leak sounds.

The system can perform correlations over 1 km or more, depending on conditions and antenna configuration, while hydrophones can provide additional acoustic information when required.

What is the Gutermann AQUASCAN TM2 used for?
It is primarily used to locate underground water leaks, especially on large-diameter trunk mains, plastic pipes, and other difficult pipeline systems.

Can the AQUASCAN TM2 detect leaks on plastic pipes?
Yes. The system is specifically designed to work with both metallic and non-metallic pipe materials, including plastic pipes.

How far can the system correlate?
Gutermann documents correlation over 1 km or more under suitable conditions. Actual range depends on pipeline conditions, terrain, radio environment, antenna setup, and other factors.

What are the hydrophones used for?
Hydrophones can be connected at hydrants or directly to the pipeline to capture additional leak-noise information, which can be particularly useful when conventional surface-mounted sensors provide weak signals.

What does the Auto Filter do?
The Auto Filter automatically selects relevant frequency ranges to enhance the correlation peak, helping operators identify weak leak signals more easily.

Is the AQUASCAN TM2 a non-invasive leak detector?
Yes. The system uses externally mounted sensors and wireless communication, avoiding the need for drilling or intrusive access to the main pipeline.
