What is claimed is: 1. An apparatus for measuring and dispensing solid dry flowable material, comprising: a supply container for holding material, said supply container comprising a shut-off valve; a reserve hopper; means for connecting said supply container to said reserve hopper, said connecting means comprising a flexible, compressible conduit, an output transfer valve, and an input transfer valve, said compressible conduit being attached to the shut-off valve at one end and to an inlet on said output transfer valve at the other end, said output transfer valve capable of attachment to the input transfer valve, said input transfer valve connected to said reserve hopper; means for weighing said reserve hopper; means for dispensing material from said reserve hopper; and means for regulating the weight of material dispensed from said reserve hopper. 2. The apparatus of claim 1 wherein said weighing means comprises a load cell attached to said reserve hopper for measuring the amount of product dispensed from said reserve hopper. 3. The apparatus of claim 1 further comprising a housing. 4. The apparatus of claim 1 wherein said supply container is transportable, refillable and environmentally closed. 5. The apparatus of claim 1 wherein at least a portion of the sides of said supply container slope. 6. The apparatus of claim 1 wherein said conduit is a hose. 7. The apparatus of claim 1 wherein said output transfer valve and input transfer valve are both product specific. 8. The apparatus of claim 1 wherein said output transfer valve is one-way. 9. The apparatus of claim 1 further comprising a reserve hopper refill valve disposed between the input transfer valve and the reserve hopper. 10. The apparatus of claim 1 wherein said regulating means comprises a controller. 11. The apparatus of claim 1 wherein said dispensing means comprises a dispensing valve. 12. The apparatus of claim 11 wherein the dispensing valve is a magnetic solenoid. 13. The apparatus of claim 1 further comprising means for transporting material dispensed from said reserve hopper. 14. The apparatus of claim 13 wherein said transporting means is hydraulic, pneumatic, mechanical or portable. 15. The apparatus of claim 14 wherein said transporting means is a hydraulic or pneumatic conduit. 16. The apparatus of claim 15 further comprising means for monitoring the flow of fluid through said conduit. 17. The apparatus of claim 14 wherein said transporting means is a portable container. 18. The apparatus of claim 17 further comprising means for identifying said supply container and said portable container and means for regulating flow of appropriate materials thereinto. 19. A method for measuring and dispensing solid dry flowable material, comprising: placing a quantity of solid dry flowable material into the supply container of an apparatus of claim 1; discharging a portion of the material therefrom into the reserve hopper of said apparatus; weighing the reserve hopper; dispensing material from the reserve hopper; and regulating the weight of material dispensed from the reserve hopper.
