ABSTRACT:
An automated chemical dispenser for the dispensation of a chemical into a liquid whereby premature contact of the chemical with the liquid's condensate is to be avoided. The device is, for example, especially well suited for the dispensation of sodium dichlor granules into swimming pool water as it is not susceptible to malfunction due to encrustment. A ganged valve arrangement is actuated from above to prevent any deposition of chemical on the actuation mechanism and thereby allows the chemical to freely drop into water filling a mixing basin situated directly therebelow. The actuation of critical valves at the proper moment and in a preselected sequence is governed by a controller that is preferably prompted by a sensor probe disposed within the dispenser that is capable of accurately monitoring the chemical's concentration within the pool.
