CHEMICAL DELIVERY DATA ACQUISITION SYSTEM
First Claim
1. A car wash, comprising:
- at least one dispensing system for directing one or more car wash cleaning solutions onto a vehicle during a car wash cycle;
at least one mixing system for mixing a concentrated cleaning agent with a water stream to form the car wash cleaning solution, said mixing system including a concentrate flow control; and
at least one supply system for supplying the concentrated cleaning agent from a bulk storage container, wherein the supply system includes a monitoring assembly for determining an amount of the concentrated cleaning agent supplied to the mixing system on a per car basis.

Abstract
A system for controlling and monitoring the chemical usage in a car wash systems that form an aqueous cleaning solution by diluting a cleaning chemical concentrate in a process water stream to form. Level sensors are mounted to the bulk containers containing the chemical concentrate to measure and track the usage of the chemical concentrates. The usage data is collected and used to adjust flow rate controllers controlling the dilution of the concentrate into the process water stream. The system can be integrated into continuous processes where the aqueous cleaning solution is dispensed immediately after production and batch processes where the cleaning solution is stored temporarily before being dispensed onto a vehicle.

10. A method for monitoring and controlling cleaning agent usage in a car wash, comprising:
-
providing a supply system including a monitoring assembly for measuring an amount of a concentrated cleaning agent in a bulk storage container; regulating the amount of concentrated cleaning agent supplied to a mixing system with a concentrate flow control such that the concentrated cleaning agent can be combined with a water stream at a predetermined dilution ratio to form the car wash cleaning solution; and measuring the amount of concentrated cleaning agent supplied to the mixing system for each car wash event. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
