Abstract: A system for controlling the flow of fluid through a line (3). The system may include first and second valves (A, B; and 6, 7) in the line (3). Between the first and second valves is located a chamber (52, 82), part of which may be filled with fluid having a variable volume (52), and another part of which is filled with a measurement gas (82, V.sub.1), such as air. The chamber may be isolated from the pressure effects in the rest of the line by closing both valves. The valves may also permit fluid to flow into or out of the chamber. The second portion of the chamber has a common boundary with the first part in such a way that the combined volume of the first and second parts is constant. A loudspeaker (22, 33, 571) creates sound waves in the gas in the second part of the chamber, in order to measure the volume of the fluid in the first part. A controller directs the operation of the valves and controls positive and negative pressure sources, which may be used to create subsonic pressure variations to produce the desired flow. The volume measurement is achieved by acoustic volume measurement techniques.

Abstract: A fluid metering device mixes a predetermined quantity of a first fluid with a larger quantity of second fluid supplied to the device at a higher pressure on each cycle. The pressure of the second fluid provides the force necessary to motivate a first pumping means which on movement to an ''outlet'' position within a housing displaces the mixed fluids on an outlet side of the first pumping means to their destination. Movement of the first pumping means actuates a second pumping means which pumps a predetermined quantity of the first fluid into the housing on each cycle. On the maximum pumping stroke of the first pumping means being reached at the ''outlet'' position, a passage is opened in the first pumping means which is then restored to an ''inlet'' position, the second fluid in the housing passing through the passage during such restoration and thus being available for despatch on the next pumping stroke. When the first pumping means reaches the ''inlet'' position the passage closes and a further pumping cycle commences.

The metering element in each unit has two spaces divided by a flexible impermeable diaphragm, each space accommodating a perforated limiting plate. These spaces communicate through inlet valves in each unit with a pump delivering the respective component from its storing reservoir and, through outlet valves, with the common, further reservoir. The units are fitted with sensors indicating the flow rate of the solution components.

First and second, quick-acting flow interrupting means are operatively associated with said fluid supply line at spaced locations thereon, and a cavity of substantially constant volume is formed between said flow interrupting means. In operation, and for the formation of each of said segments, said first flow interrupting means are opened to effect the filling of said cavity with said pressurized fluid whereupon said first flow interrupting means are closed and said second flow interrupting means opened to effect the flow of said pressurized fluid from said cavity into said fluid stream to form said segments. A form of the invention is disclosed wherein said fluid supply line is constituted by a compressible, resilient tube and said flow interrupting means comprise means to compress and close said tube at spaced locations thereon. In this disclosed form, the cavity is formed by the volume of the tube which extends between said flow interrupting means.
