The invention claimed is: 1. An apparatus for the delivery of slurry solution, comprising: an ultrasonic flow meter that is connected to an inlet for slurry solution from a fluid preparation manifold and is positioned between the fluid preparation manifold and a slurry delivery arm; a proportional valve that is connected to the ultrasonic flow meter; and a shutoff valve positioned between and connected to the proportional valve and the slurry delivery arm. 2. The apparatus of claim 1, wherein the ultrasonic flow meter, shutoff valve, and proportional valve are encompassed by a drawer of the apparatus, and the drawer further comprises a controller and flow meter converter. 3. The apparatus of claim 2, wherein the controller and flow meter converter are housed in one assembly in the drawer. 4. The apparatus of claim 1, further comprising a drawer that encompasses the ultrasonic flowmeter, the proportional valve, and the shutoff valve. 5. The apparatus of claim 1, wherein an inlet to the ultrasonic flow meter is configured for flow of greater than 15 psi. 6. The apparatus of claim 1, wherein the proportional valve is positioned between the flow meter and the shutoff valve. 7. The apparatus of claim 6, further comprising a stepper motor connected to the proportional valve. 8. The apparatus of claim 1, wherein an inlet to the ultrasonic flow meter is configured for a flow of about 15 mL/min to about 1.5 L/min. 9. An apparatus for the delivery of slurry solution, comprising: an ultrasonic flow meter positioned to receive slurry solution from an inlet for fluid from a fluid preparation manifold; a proportional valve and stepper motor in communication with and connected to the ultrasonic flow meter, wherein the proportional valve and the stepper motor are connected; and a reverse flow restrictor in communication with and connected to the proportional valve and a slurry delivery arm, wherein the reverse flow restrictor is between the proportional valve and the slurry delivery arm. 10. The apparatus of claim 9, wherein the reverse flow restrictor is a degasser, two way valve, or check valve. 11. The apparatus of claim 9, wherein the ultrasonic flow meter, shutoff valve, and proportional valve are encompassed by a drawer of the apparatus, and the drawer further comprises a controller and flow meter converter. 12. The apparatus of claim 11, wherein the controller and flow meter converter are housed in one assembly in the drawer. 13. The apparatus of claim 9, further comprising a drawer that encompasses the ultrasonic flowmeter, proportional valve and stepper motor, and reverse flow restrictor. 14. The apparatus of claim 9, wherein an inlet to the ultrasonic flow meter is configured for flow of greater than 15 psi. 15. The apparatus of claim 9, wherein the proportional valve is positioned between the ultrasonic flow meter and the reverse flow restrictor. 16. The apparatus of claim 15, wherein an inlet to the ultrasonic flow meter is configured for a flow of about 15 mL/min to about 1.5 L/min. 17. An apparatus for the delivery of slurry solution, comprising: an inlet for slurry solution from a fluid preparation manifold; an ultrasonic flow meter that is connected to the inlet and is adapted to receive slurry solution from the inlet; a proportional valve that is connected to the ultrasonic flow meter to receive slurry solution from the ultrasonic flow meter; and a reverse flow restrictor that is connected to the proportional valve to receive slurry solution from the proportional valve and that is connected to an outlet for delivery of slurry solution to a slurry delivery arm. 18. The apparatus of claim 17, wherein the reverse flow restrictor is a degasser, two way valve, check valve, or shutoff valve. 19. The apparatus of claim 17, wherein the ultrasonic flow meter, reverse flow restrictor, and proportional valve are encompassed by a drawer of the apparatus, and the drawer further comprises a controller and flow meter converter. 20. The apparatus of claim 19, wherein the controller and flow meter converter are housed in one assembly in the drawer.
