General Description

Channel, through which water flows, of rectangular section with transparent walls that enable to observe all the experiments. Water is taken from the storage tank by means of a hydraulic pump, with speed regulation, and, by the pipe, it is driven to the inlet tank, where there is a soothing of flow. After that, the water flows through the channel that discharges in the reception tank. Finally it comes back to the storage tank, completing the closed circuit.

The unit includes the instrumentation and the suitable sensors (flow, pressure, etc.) to control and to measure the most representative parameters.

To regulate the flow through the channel, there is a valve at the output of the pump.

To measure the flow there is an orifice plate flow sensor and a Venturi type flow sensor. The flow also can be measured with the flow sensor of the Basic Hydraulic Feed System (FME00/B).

A limnimeter (CFRMC) is required to measure water level. Besides, a Pitot tube with tubes manometer board (CFTPC) us required to measure velocity/flow.

The channel is assembled on two supports, with a system to control the inclination of the channel.

There is a wide range of available accessories.

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.
