Level, speed and flow information of the 6x8x14000 mt power plant water channel, including in the regulator and forebay, were transferred wirelessly to the SCADA System in the powerhouse. It is aimed to evaluate the turbine efficiency with instant data of regulator and loading flow information and power plant production information. In addition, with retrospective reporting, how much production was made and how much water was consumed at what hours can be compared. Laser Doppler equipment was used to detect the velocity of the water passing through the channel.
