Set up facilitate investigation of a Francis turbine. It consists of closed water circuit with pump, motor, flow control valve and tank with optional cooling. Pump is provided with variable speed via frequency converter and flow rate can be adjusted via flow control valve. It is provided to load the turbine by use of a synchronous machine as generator. Rotor and guide vanes of the turbine are completely visible. Adjustable guide vanes are provided for setting different angles of attack. There is Non-contact speed measurement at the generator shaft and a force sensor for measuring the driving torque.
