ABSTRACT:
A transportable frame includes a plurality of liquid material storage tanks and dry material storage bins mounted thereon. There are smaller liquid material storage tanks and larger liquid material storage tanks. The metering system for the larger liquid material storage tanks has a flow rate range varying from a low end to a high end. The metering system for the smaller liquid material storage tanks has a second flow rate range varying from a low end to a high end. The low end of the second range is lower than the low end of the first range, and the high end of the second range is between the low and high ends of the first range. There are also larger and smaller dry material storage bins with similarly sized metering systems for the dry material storage bins. The dry material storage bins are partially supported from the transportable frame by load cells which are mounted on extendable hydraulic cylinders. The system also includes apparatus for controlling the storage and metering of the additives within the tanks and bins. This apparatus includes an element which determines how much additive is being discharged from an additive storage tank and an element for sensing how much of a primary substance is being discharged from a primary substance container. Based on the operation of these two elements, a third element controls the amount of additive discharged. This third element includes a microprocessor which controls the metering based on inputs from load cells, flowmeters, and manual data entry members of which the additive determining and primary substance sensing elements and the control element are comprised.
