Abstract

The disclosure relates to a system for continuous delivery of a measured flow of liquid to a processing apparatus comprising a reservoir (10) for holding a bulk supply of the liquid and, an intermediate vessel (12). A first pump delivers liquid from the intermediate vessel to processing equipment at one rate. A second pump (13) delivers liquid from the reservoir to the intermediate vessel of a second much faster rate. A pressure transducer (14) continuously monitors the weight of the liquid in the vessel and controls the first pump accordingly to deliver the required weight of liquid at the required rate to the processing equipment. The pressure transducer determines when the weight of liquid in the intermediate vessel has reached a minimum position to initiate operation of the second pump (13) to refill the vessel and a further device terminates operation of the second means when the liquid level in the vessel reaches a maximum position.
