The 6000 series flowmeters work according to variable area principle, which is obtained by a float that moves inside a borosilicate glass tapered tube. The fluid flows up through the tapered tube forcing the float to a position with sufficient free area to enable the flow to pass, where there is an equilibrium of forces. Each position of the float corresponds to a value of flow rate. 

A fluid flows upwards through a tapered tube in vertical position and displaces a float until it reaches an equilibrium point. Each position of the float corresponds to a different flow rate, which is shown by the equivalent scale engraved directly on the tube.

A spring C keeps a disk B in zero flow rate position. When the fluid flows through the disk at a specific speed, a force is made on the disk B, moving it to an equilibrium position.

The first figure shows the COVOL flowmeter at the beginning of a cycle, when the measuring chamber (in blue) is completely full. The flow of the liquid through the flowmeter makes a force on the oscillating piston, so that it starts turning. From this moment, the measuring chamber is divided in two parts: inlet (in red) and outlet (in blue).
