Abstract:
A solution dispenser for dispensing, at a metered rate, a solution contained within a storage tank into a flow of fluid in a flow line, the solution dispenser comprising:an inlet connection and an outlet connection for accepting fluid diverted from the flow line and for returning fluid to the flow line; a crossover connection connecting the inlet connection to the outlet connection providing a fluid flow path that allows fluid diverted from the flow line to move in path that is in parallel with a path of the flow line; an agitation tube in fluid communication with the crossover connection proximate to the inlet connection for placing the crossover connection in fluid communication with the storage tank; a pickup tube in fluid communication with the crossover connection proximate to the outlet connection for placing the crossover connection in fluid communication with the storage tank; and a vent port associated with the pickup tube for use in exhausting air from the storage tank into the flow line and, thereafter, for determining a mix ratio of fluid returned from the storage tank and fluid in the flow line.
