Continuous liquid stream digital blending system

摘要: The present invention consists of a method and apparatus providing for the continuous stream blending, preferably on mass ratio basis, two or more liquids. Each individual liquid is synchronously dosed in precise to common mixing point. flow each on-off digital. Repeated doses defined matching interval, referred as synchronous digital flow, interspersed with interval no constitutes at net rate sufficient meet exceed some required take-away blended In one preferred embodiment, dose produced measured by four element consisting servo motor controller, precision positive displacement pump, Coriolis meter shut-off device. controller establish control periodic intermittent necessary displace precisely interval. against millisecond clock. used only totalize define desired during device ensures delivery automatically adjusted electronics until delivered
