Abstract: Apparatus for adding measured quantities of concentrates or solutions, e.g., particularly fluoride salt solutions, to a second liquid, e.g., fresh water as supplied by municipalities to ordinary residences. The apparatus is particularly adapted to be fitted into a conduit carrying a supply of fresh water to a source to be supplied with fluorinated water, e.g., a residence. It is constituted generally of an outer vessel within which a tubular flow nozzle is enclosed. The nozzle is provided with high pressure and low pressure sides, and lateral outlets from such high and low pressure sides. A flexible bag containing, e.g., a fluoride solution for injection into the fresh water, can be operatively connected to the low pressure outlet, while the external portion of the bag is placed under the influence of the high pressure outlet such that when fresh water is passed through the nozzle the differential pressure causes solution to be metered via the low pressure outlet into the axial opening within the tubular flow nozzle where it is picked up, admixed or dissolved within the fresh water, and dispensed through the conduit as fluorinated drinking water.
