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.
