Abstract (en)
[origin: FR2781392A1] The device has two elements (24,25) for making volumetric measurements of an additive based on a pre-determined amount of liquid. The first device (25) is designed to make measurements for additions over a wide range e.g. from 2 to 10 percent. The second device (24) operates over a narrower range, e.g. 0.2 to 1.9 percent. The two devices are mounted in series upstream of a mixing device (28). The mixing device (28) mixes the amount of liquid containing the additives with other constituents of the final material.
