The present invention involves a method for evaluating sensor data in a fluid carrying network (10) and a corresponding evaluation unit (70). Thereby the method comprises the steps of : - providing a numerical network model (40), which at least partly represents an acoustic property of the fluid carrying network (10); - receiving sensor data (SD) of at least one acoustic sensor (20i,...,20n) placed on the fluid carrying network (10); - calculating model data (MD) by using the numerical network model (40); and - evaluating the received sensor data (SD) by considering the model data (MD). This way efficient and reliable leak detection is achieved, including a precise localization of the detected leakage within the fluid carrying network (10). |
