A FILL SYSTEM CONTROL APPARATUS

摘要

An apparatus for accurately filling packages in a filling machine (10). The filling machine (10) overcomes the problems of filling inaccuracies by providing means (22) for continuously controlling the rate of inflow filling fluid into the filling machine (10). Such filling machine (10) includes a balance tank (18) for storing a product fluid and a valve mechanism for controlling the flow of product fluid to the balance tank (18). The opening of the valve mechanism (16) is responsive to an input signal for controlling the size thereof in a generally continuous manner whereby a plurality of different sized openings may be used. A level probe (20) is positioned in the balance tank (18) for providing an output indicative of the level of the product fluid in the balance tank (18). A controller (22, 28, 30, 42, 44 and 46) responsive to the output signal of the level probe is used to provide the input signal to the valve mechanism in response to the sensed product fluid level to control the flow of product fluid into the balance tank (18).
