Abstract:
A system for controlling delivery of water and a plurality of chemical products to a washer comprising:a) distribution means for distributing a plurality of chemical products to a specified washer having man input line;b) a water supply reservoir coupled through a water line to an input end of said distribution means;c) a plurality of chemical holding containers, coupled to said distribution means through separate corresponding pump means, whereby a chemical product is selectively drawn from such containers by said corresponding pump means into said distribution means, said pump means outputs are coupled to said distribution means downstream of said input end of said distribution means;d) displacement pumping means for pumping said chemicals and water through said distribution means to said specified washer;e) mixing means coupled to said distribution means for mixing said chemicals with the water from said reservoir;i) a fluid pressure sensor coupled to said distribution means downstream of said mixing means;g) controller means for controlling delivery of water and chemical products, said controller means coupled to said fluid pressure sensor for monitoring and detecting pressure in said distribution means, whereby a high or low pressure level acts as an interrupt signal whenever a corresponding chemical product or water is needed for said specified washer.
