Apparatus for filling liquid.

摘要

A method for filling a predetermined amount of liquid in a container is improved so as to enable to speed up and precisely control the filling operation regardless of change of properties of the liquid. The improvements exist in that the weight of liquid contained within a weighing balance (9) is measured by said balance and a filling control valve (14) provided at an outlet of said metering container is controlled in response to a signal issued from said weighing balance (9), and thereby a predetermined amount of the liquid can be filled in a container (16) such as a bottle, a can or the like. An apparatus for practicing the improved method is also proposed, wherein a control unit for opening and closing the filling control valve (14) and a feed control valve (2) connected to a liquid feed source in response to a signal issued from the weighing balance (9) is provided, an inlet of the metering container (25) is connected via a flexible pipe (5) to an outlet of the feed control valve (2), and an outlet of the metering container (25) is connected via a flexible pipe (11) to an inlet of the filling control valve (14).
