Abstract
A method of delivering a liquid detergent product which may be caustic, is described. In particular, a predetermined volume of water is dosed into a container using a flow meter, a valve means, and, optionally, a water supply pump means. A pump means is activated to deliver the liquid detergent product into the container until it is completely filled as controlled by a level sensor located in the container. The contents of the container are then delivered. A device for carrying out the method is also described.
