WFPC Computer Controlled Unit to Study Water Flow Principles
The Computer Controlled Unit to Study Water Flow Principles, "WFPC", is composed by both a closed and an open water circuit, thus allowing the observation of fluid's behavior in each of them.
The Computer Controlled Unit to Study Water Flow Principles, "WFPC", is composed by both a closed and an open water circuit, thus allowing the observation of fluid's behavior in each of them. The selection of the circuit can be made by means of a three-way manual valve with two outputs: one assigned to the pipe passage and another assigned to the open channel entrance. Both channels are transparent so the process can be fully visualized.
A computer controlled pump drives the fluid through the conduit. The consumption of the pump can be measured by computer. Depending on the disposition of the three-way valve, the fluid will enter the closed conduit or pass into the open channel. Before entering one of the two paths, the fluid passes through a flow sensor. The flow rate can be regulated by the control valves assigned to each path or by computer.
The closed conduit presents different singularities or accidents: two 90º angles and two bends, in different sections of the tube, an expansion, a Venturi tube, an orifice plate and a contraction. Three pressure sensors can be interchanged in the sixteen available measuring points in order to calculate the pressure drop in each of these sections.
The open channel has a broad-crested weir and a sharp-crested weir. It also has a limnimeter with displacement sensor to detect the water height that can be placed anywhere in the channel.
At the end of both circuits the fluid goes to a storage tank, where it remains until the pump is activated again.
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.
