SONO-MIX MINI Version 2_7

5.2. Assembly Dimensions

SONO-MIX MINI can either be installed at the base or the side wall of a mixer. One fact to consider is
that the installation into the mixer base also enables the measurement of smaller material quantities.

A cut-out must be performed in the mixer base before welding on the mounting frame and it is
necessary to verify the fit of the frame and the probe at the base, respectively the wall.
