Full Description

Usually calibrating a model involves adjusting data, but sometimes the process of calibration reveals that unusual conditions affected the measurements. Models predict system performance and pressures by calculating flow rates and head losses in pipes. For true calibration, the model must match both flow and head loss measurements. Matching one of the other is not good enough. Errors sometimes can compensate for each other and make an inaccurate model appear to be calibrated. Four case studies of successful calibration are presented.
