The equipment set up comprising flow manifold, electronic interfaces for dada generation and for solenoid valves driving
presented a weight about 1.5 kg. The electronic parts were installed into a metallic box with dimension of 20 cm
wide, 25 cm height and 20 cm depth. The solenoid valves ware installed at front face of the metallic box, thus permitting easily maintenance. In this sense, the downsizing requirement was achieved.
