ABSTRACT:
Fluid inductor and metering device for handling and mixing concentrated chemicals such as herbicides and pesticides. In one mode of operation, the concentrated chemicals are first drawn by a transfer pump from their storage container or containers into a graduated chamber and thereafter added into a primary water flow in a metered manner. In addition to being operable in a batching manner, the apparatus of the present invention can also be used to continuously inject the concentrated chemicals into the primary water flow directly from their storage containers as well as to back flush water through the storage containers to clean them. In the preferred embodiment, all of these operations can be accomplished using only the force of one transfer pump and by the manipulation of a single valve member.
