The present invention relates to a device for extracting a substance for the preparation of a drink. This device includes a first, fixed piece and a second piece that is movable relative to the first about an axis of rotation lying at the rear of the two pieces, with the front of each piece providing a cavity for the substance to be extracted. The device also includes a system for closing and opening the two pieces. This system possesses a two-armed closing lever and two traction rods. The two arms of the closing lever are arranged to rotate about a first pivot on each side of the second piece. The traction rods are arranged to rotate about a second pivot on each side of the first piece. The ends of the two arms of the closing lever and the traction rods are fixed by means of a third, movable pivot so as to interact mutually in order to cause the closing and opening of the device.

The method of claim 50, wherein the parameter indicative of the flow momentum is measured at a location having a restriction in the conduit. 52. The method of claim 51, wherein the restriction comprises a venturi. 53. The method of claim 50, wherein the restriction homogenizes the fluid mixture before the at least one parameter of the fluid mixture is measured. 54. The method of claim 50, wherein the flow meter is selected from at least one member of the group consisting of a flow rate meter and a phase fraction meter. 55. The method of claim 54, further comprising measuring the pressure or temperature of the fluid mixture. 56. The method of claim 55, further comprising calibrating either the flow rate meter or the phase fraction meter using the measured pressure or temperature. 57. The method of claim 55, wherein at least one parameter measured by the flow rate meter is indicative of the flow rate of th
