Abstract
Electroplating processing systems according to the present technology may include a recirculating tank containing a first volume of processing fluid. The recirculating tank may be fluidly coupled with a delivery pump. The systems may include a vessel configured to receive the processing fluid from the pump. The vessel may include an inner chamber and an outer chamber, and the inner chamber may be sized to hold a second volume of processing fluid less than the first volume of processing fluid. A liquid level sensor may be associated with the vessel to provide a liquid level indication in the outer chamber. The systems may include a return line coupled with an outlet of the vessel and coupled with an inlet of the recirculating tank. The systems may also include a return pump fluidly coupled with the return line. The return pump may be electrically coupled with the liquid level sensor.
