FLUID DISPENSING APPARATUS AND METHOD

摘要

A fluid dispenser and method of operating the same. The fluid dispenser c an include a wheel driven by diluent passing along a flow path in the fluid dispenser. The wheel can be connected to a pump to pump fluid from a reservo ir for dispense into the diluent. In some embodiments, the ratio of wheel ro tations to pump cycles is selected to provide a desired and repeatable dilut ion ratio of concentrated fluid to diluent. The fluid dispenser can be porta ble and/or disposable, and in some embodiments is adapted for installation o n an upper rim of a reservoir wall. Also, the fluid dispenser can be provide d with a baffle limiting the velocity and impact of incoming diluent to the wheel driving the pump, thereby improving dosing accuracy of the dispenser i n some embodiments.
