Descrição Geral

The Computer Controlled Flow Channels, "CFGC", are hydrodynamic channels to perform multiple hydraulic tests. They consist of a rectangular section channel with tempered glass transparent walls through which water flows. Water is impelled by a pump from the storage tank and driven to the inlet tank through the pipe. In the inlet tank there is a flow stilling device that allows for performing different experiments without hydraulic disturbances. Afterwards, water flows through the channel and is discharged into the reception tank, finally returning to the storage tanks and completing the closed circuit.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
