Formulating chemical solutions based on volumetric and weight based control measurements
First Claim
1. A system for formulating a chemical solution by combining water with at least one component concentrate, the system comprising:
- a storage tank for storing the at least one component concentrate;
an output port operable to receive the water from a water source and the at least one component concentrate from the storage tank and dispense the water and the at least one component concentrate to a solution container for forming the chemical solution therein;
a flow meter operable to measure volumetric readings representing a volume of the water communicated between the water source and the output port;
a weight measuring device operable to measure weight readings representing an actual weight of the at least one component concentrate contained in the storage tank; and
a controller operable to control supply of the water and the at least one component concentrate to the output port based on the volumetric readings and the weight readings to form a specified amount of the chemical solution.

Abstract
A system and method for formulating a chemical solution using both volumetric and weight based measurements of components of the chemical solution is disclosed. The components of the chemical solution include water and at least one other component, which may take any form, such as, without limitation, liquid, solid, powder or gaseous form. Formulation of the chemical solution is administered by combining water with the one or more other components at an output port, from which this combination is dispensed to a solution storage tank. In response to a user'"'"'s request to formulate a specified amount of the chemical solution, the volume of water provided to the output port is monitored by a flow meter and the weight of the other component(s) provided to the output port is monitored by one or more load cells. Based on such monitoring, appropriate amounts of water and the other component(s) are combined together to formulate the specified amount of the chemical solution in the solution storage tank.
