The technical development of hydraulic machinery has gone towards lighter components and higher power concentration levels. A deregulation of the power market world-wide means that the machines experience more transient loads and are sometimes operated at off-design points. Those facts demand a more precise dynamic analysis at the design level of hydraulic machinery than what was formerly customary. Mechanical engineering needs enhanced tools for this purpose. Prediction models need to be validated against experimental data. There are limited possibilities to perform experimental investigations of hydropower prototypes. Fundamental in an experimental dynamic analysis is to determine the forces acting on the machine. This paper is concerned with a monitoring system to estimate the angular resolved pressure field on the suction- and pressure side of a prototype Kaplan runner blade. By measuring the pressure at different positions on the runner blade, we have a tool to determine the hydraulic load acting on the runner. This is part of an experimental dynamic analysis of the behavior of 10 MW prototype of a low-head Kaplan prototype lodged in an old machine hall inaugurated 1914 situated above the polar circle in Porjus, Sweden.
