Abstract: The method serves the purpose of the acoustic leak detection in a district heating supply network (3), in which a heat transfer medium is circulated between a combined heat and power plant (1) and points of use (5). The points of use (5) have heat meters (10), which operate with ultrasonic flow meters, which operate with ultrasonic flow meters, which can be operated in a leak detection mode for the acoustic leak detection, whereby the acoustic signals detected in the leak detection mode are filtered to eliminate extraneous noises, in particular pump noises.
