A method and system for routing a delivery vehicle to a chemical usage facility is disclosed. The chemical usage facility includes one or more chemical dispense systems that dispense one or more chemical product. The quantity of each chemical product remaining is measured and communicated to a central management facility. The central management facility analyzes a trend in product usage to predict when the product quantity will reach a threshold depletion point. The chemical usage facility is scheduled on the route according to the predicted time associated with the threshold depletion point.

Scheduling delivery of chemical products based on a predicted estimated time of exhaustion

A flow verification sensor apparatus () is used with a constant volume pump () that pumps a liquid product () from a container (). A plummet () is positioned in a flow tube (). A sensor () is positioned upward from the lower end of the flow tube (). A timer () measures the length of time for the plummet () to move from a first position to a second position after activation of the pump (). Suitable alarms () are operated to indicate low flow or out of product conditions.

Flow verification mechanism

A conveyor and lubricating apparatus includes a conveyor and a dispensing device. The conveyor includes a conveyor surface and is provided for transporting items on the conveyor surface. Exemplary items that can be transported include plastic bottles, glass bottles, cans, and cartons. The dispensing device provides a spray pattern of a lubricant composition onto the conveyor surface. The dispensing device includes a nozzle that generates the spray pattern, a lubricant dispensing line that supplies the lubricant composition to the nozzle, a nozzle valve that opens and closes in response to the pressure conditions within the lubricant dispensing line to control flow of the lubricant composition to the nozzle, and a spray valve constructed to move between a first position and a second position, wherein the first position causes pressurization of the lubricant dispensing line and the second position provides depressurization of the lubricant dispensing line. A dispensing device is provided and a method for applying a lubricant composition to a conveyor is provided.
