Abstract
A system for the operation of a number of commercial washing machines and automatically feeding liquid chemicals to the washing machines. The system has chemical reservoir pods with a pressure sensor and an output valve on each. The chemical pods are supplied with liquid chemical by refill pumps. The quantity of chemical in a chemical pod, and the quantity of chemical dispensed from each chemical pod is calculated from information received by a controller from the pressure sensor to determine when to open and close the valve. A further pressure sensor is provided in the supply pipe to each washing machine to verify and measure flow quantity of water and chemical to the machine.
