Abstract
Apparatus and method for dispensing admixtures based upon weight. One or more admixture storage containers are supported in one embodiment by a suspended platform, and in another embodiment by brackets. A weight sensing system such as a single load cell is used for weighing the contents of the admixture storage containers. The platform or brackets are arranged so that the load cell is responsive to less than 100% of the weight in the containers. The containers are filled to a predetermined weight, and the contents are dispensed from each container in series or simultaneously.
Claims12
An admixture dispensing system, comprising:
- a. one or more admixture storage containers;
- b. means for supporting said one or more storage containers;
- and
- c. weight sensing means associated with said means for supporting said one or more storage containers, said weight sensing means coupled to said means for supporting said one or more storage containers, so as to support a proportion of less than 100% of the weight of said one or more storage containers on said admixture storage container support means.
A process for dispensing admixtures based upon weight, comprising:
- a. arranging one or more admixture storage containers on admixture storage container support means, each of said admixture storage containers having fill means and discharge means associated therewith;
- b. supporting less than 100% of the weight of said admixture storage container support means on weight sensing means;
- c. filling said one or more of said admixture storage containers with admixture via said fill means to a pre-determined weight as measured by said weight sensing means;
- d. discharging said admixture from one or more of said admixture storage containers.
