2.9 The regulating ring
Function of the regulating ring
Perfect separation of a liquid mixture is only possible when the bowl has been
correctly adapted to the density difference between the light liquid (e.g. oil) and
the heavy liquid (e.g. water).
To achieve this, select and fit the regulating ring from the set furnished (with dif-
ferent inner diameters) whose inner diameter corresponds to the difference in
density between the two liquid components.
