This document describes leak detection technologies from Trotec for drinking water systems, including acoustic and trace gas leak detectors, wireless data loggers, and pressure loggers. The LD6000 combi detector allows acoustic pinpoint leak detection and trace gas detection in one device. Wireless loggers like the LD5L can be used for long-term monitoring and localization of leaks by measuring sound levels overnight and transmitting data to a mobile receiver. Pressure loggers such as the LD5DL are designed specifically for monitoring water pressure networks.
