Abstract

Fluid circulation and leveling systems and methods of using the same are described. A fluid circulation system includes a fluid mixing chamber and open fluid chambers in fluid communication with the fluid mixing chamber. Each open fluid chamber includes a microfluidic fluid leveling conduit with an orifice disposed in the open fluid chamber at a minimum fluid level associated with a corresponding minimum fluid volume. A controller causes a first pump to generate a first direction of fluid flow during a first time period between the open fluid chambers, and causes the first pump to generate a second direction of fluid flow during a second time period between the first and second open fluid chambers. The controller also causes a second pump to generate a flow of fluid during a third time period from one of the first and second open fluid chambers into the fluid mixing chamber.
