The specially designed flow measuring controller automatically collects the water level. And starting the cableway flow measuring equipment according to the water level change, and calculating the flow according to the collected data such as the water depth, the vertical line flow velocity, the corresponding water level, the starting point distance and the like.

Because the flow velocity of the vertical lines is measured by adopting the ADCP, the number of the vertical lines is set according to a standard precision measurement method. Therefore, high-precision flow achievement can be obtained for riverways with turbulent flow velocity vertical distribution and transverse distribution. The actual measurement depth of water of cableway ADCP also adapts to the section that the riverbed has the erosion and deposition change, and two limit switches on the limit travelling crane frame are connected on the ADCP control box.
The ADCP is embedded in the fish lead, and no matter the high-speed water flow or the extremely low flow velocity, the ADCP can be kept on the position of the vertical line in a normal posture, so that the measurement precision of the flow velocity of the vertical line is ensured.
