AUTOMATIC MEASUREMENT SYSTEM FOR HYDRAULIC EXPERIMENT

摘要

PURPOSE:To perform hydraulic experiments automatically according to preset experimental conditions by using a microcomputer for arithmetic processing in weir water level measurement and pressure measurement by manometer, and recording necessary hydraulic experiment results automatically. CONSTITUTION:A waterway is provided with plural motor-driven valves 32, weirs for flow rate measurement, and water level detectors 33 for the weirs, and pressure measurement holes are formed at respective necessary parts of the waterway; and opening-extent signals of the motor-driven valves 32 which links the holes to a manometer water level detector 34 equipped with a solenoid valve 15 for switching measurement points, measured values of the weir water level detectors 33, and measured values of the manometer water level detectors 34 are inputted to a central processing unit (CPU) 36 and an operation display board 37 through an interface 35 and displayed on the operation display board. The CPU36 controls the opening and closing operation of the motor-driven valves 32 according to the experimental conditions and input signals from respective detection terminals.
