TIME VOLUMETRIC FLUID DISPENSING APPARATUS

摘要

A dispensing apparatus for dispensing predetermined volumes of fluid into receptacles receives the fluid to be dispensed from a fluid supply into a reservoir. A fill tube is connected to the fluid reservoir such that it forms a closed loop with the reservoir. The fill tube minimizes the fluid turbulence that occurs inside the reservoir while the reservoir is being re-supplied with fluid from the fluid source. Additionally, the fill tube holds the predetermined volume of fluid to be dispensed into the receptacle. A fluid level sensor is disposed along the fill tube to control the volume of fluid flowing into or out of the fill tube, while a timer controls a dispense valve to meter the flow of fluid into or out of a dispense tube.
