Errors are shown in l/s and %. Valves have the following size and type: SKL is DN100 GE, WLW is DN150 GE and LCW is DN100 GE. It should be noted that high errors on the WLW valve come from the fact that the valve in the ‘Field Lab’ operates in a narrow range of pressure combination through the model training process.
