Abstract : This Patent Application discloses an apparatus and method for accurately and efficiently metering at least one compressible fluid and at least one incompressible fluid for mixing, whereby pressure and therefore density is regulated with regard to each compressible fluid, and volume is regulated with regard to each compressible fluid as well as each incompressible fluid. Compressible fluids in particular are metered more accurately because the mass of each fluid is used as the variable measurement standard, both the density and the volume of each fluid being maintained at controlled and predictable levels. Independent regulation of the volume of each fluid, e.g., in terms of flow rate, along with independent regulation of the pressure of each fluid which is a compressible fluid, serve not only to optimize metering accuracy metering efficiency as well by accounting for relative compressibilities and viscosities between or among the fluids, thereby permitting minimization of lag times between or among the flows of the fluids, in this way furthering integration of the individual metering processes of all the fluids into one cooperative system whereby the flows of all the fluids are mutually and/or concurrently controlled.
