Abstract
A system for blending fluids comprises a plurality of fluid sources to which utilization conduits are selectively connected. The blending operation for a predefined combination of fluids is controlled by a computer employing a software control program. An rf signal tag is mounted on each utilization conduit. When the utilization conduit is connected to a supply conduit for a given fluid source, a utilization signal input is provided to the computer and control program to provide assurance that the predefined fluids are connected for a given blending operation as well as the utilization conduit being properly locked on the supply conduit.
