Abstract
The invention provides an apportioning system comprising a first apportioning chamber having a first outlet and fillable with liquid to a first defined level such that if liquid is added to fill the first apportioning chamber above the first defined level, then the extra fluid drains through the first outlet, an inlet channel that distributes liquid to the first apportioning chamber, and a first electrode-based pump for moving liquid in the first apportioning chamber out the first outlet.
