This dataset contains the pressure and flow measurements for a water network with leaks at different locations. The experimental setup consists of a reservoir supplying a <i>1.5kW</i> pump. Water is pumped through a <i>25mm</i> diameter pipe with a length of <i>65m</i> . Leaks are introduced at <i>15m</i> , <i>30m</i> and <i>50m</i> and three different leak sizes are tested at each location. The dataset contains the pressures and flow measurements at the inlet and outlet of the pipe. The dataset is primarily used to investigate the effect of noise and model error for the identification of leaks using model-based leak detection strategies
