Abstract

Liquid filling apparatus and method of producing a fill or dose of a defined quantity of liquid based upon the mass of the liquid. In one embodiment, a servo motor driven rotary positive displacement pump is used to produce flow through a Coriolis mass flow meter to feed a positive shut-off filling nozzle, wherein mass flow data from the meter is used to control the servo motor- pump-nozzle to produce a precise fill dose of liquid based upon its mass.
