Problems solved by technology

If the desired concentration is not maintained in the solution and applied in the correct amounts on the streets, accidents may occur.
This correlation can, in some instances, be faulty.
This may in turn lead to an undesired salt concentration level for the solution based on fluctuations in the mixed solution.

first embodiment

[0151]In a first embodiment, aspects of the invention may be used in a corrosive environment such as mixing brine for deicing applications. Brine used for deicing is very corrosive. Minimizing the number of delicate instruments that contact the brine is important. For instance, adding a spinning flow meter in the solution may create severe maintenance problems due to continuous failure of the flow meter. While one may use a flow meter for this caustic environment, the cost of the flow meter may be high, thereby making the entire solution maker more expensive. One benefit of using this type of flow meter, however, is that it can provide highly accurate measurements of material flowing past it.

second embodiment

[0152]In a second embodiment, aspects of the invention may be used in other brining industries that have less caustic environments. For instance, aspects of the invention may be used in the cheese, beverage, or meat processing industries. Here, the food may be dipped in a brine solution that has a lower salt level than that of the deicing environment.

third embodiment

[0153]In a third embodiment, aspects of the invention may be used in industrial water supply environments in which large supplies of water or other liquid chemicals need to be mixed before being provided for subsequent processing or use. For example, hospitals, processing plants, energy generation plants and the like may require large amounts of treated water or other materials. Aspects of the present invention may be used to help mix solutions for these applications.

Abstract

A solution making system and apparatus are described. The solution maker mixes a chemical or slurry with a solvent to a desired concentration. The concentration of the solution is monitored by one or more methods. Based upon this measurement, the concentration of the solution may be adjusted.

Description

RELATED APPLICATION INFORMATION[0001]This application is a Continuation-in-Part of U.S. application Ser. No. 11 / 190,395, filed Jul. 27, 2005, whose contents are expressly incorporated herein by reference.TECHNICAL FIELD[0002]Aspects of the present invention relate to an apparatus and method and control system used to produce chemical solutions (for instance, a brine solution). More specifically, aspects of the invention relate to an apparatus for dissolving a chemical in a solvent to produce a solution of a specific concentration.BACKGROUND[0003]Chemicals dissolved in a solvent at a specific concentration are used in a myriad of industries. For example, the application of a salt solution to reduce the amount of snow and ice from roads, sidewalks, driveways and other surfaces is a common industrial practice. Salt solution is generally created by mixing rock salt and water to produce a solution. The concentration of the solution may then be adjusted by adding fresh water to dilute the...
