The EDIBON Pipe Network Unit has been designed for enabling different pipe network installations, measuring the flow and pressure, always
using water as test fluid.
The objective of this unit is to simulate the problems that could be originated in pipe networks, having this pipes different lengths and diameters,
as it happens in the cities.
With these studies, the dimensions of the networks will be clearer, in order to obtain the flow and pressure necessary for them.
A typical case is, for instance, a water distribution network in a town. Predictions of pressure and flow and their variations that take place in a
network are of great interest, because, with these data, the pipe types required for such network could be determined with more accuracy.
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), including: Control Interface Box + Data
Acquisition Board + Computer Control and Data Acquisition Software, for controlling the process and the parameters involved.
