In electricity generation process, one of the most common types of power plant is a hydro powered power plant. This power plant can be a large scale power plant (PLTA) or a small scale power plant (PLTMh). In electricity generation process with water as the main source of energy, hydraulic turbine is used as a energy conversion machine to convert fluids energy into kinetic energy. One of common used hydraulic turbine is crossflow turbine. Crossflow turbine commonly used for small-scale power plant. This turbine is suitable for rural areas in Indonesia since it can be operated on a wide range of head and flowrate of water. In order to determine the characteristics of crossflow turbine, a data acquisition system is created to record crossflow turbine’s data when operated. The data acquisition system is created using pressure transmitter, inductive proximity sensor, load cell, and orifice meter as a measurement tools. The measurement signal from each instruments are then send into a signal processing circuit and data acquisition hardware to be send into computer. The data then will be read by using LabVIEW. The data acquisition system then will be used to test crossflow turbine located in Fluid Machinery Laboratory, FTMD ITB. The test of crossflow turbine is conducted with water column head of 5 m and different flowrate. The result of the test shows that the maximum efficiency of crossflow turbine is 80,56% with maximum power output is 533 W. The maximum error of efficiency measurement is 4,71% and maximum error of power measurement is 1,15%.
