Base group consisting of:
- A transparent Plexiglas container equipped with couplings for feeding and discharge dimensions 750 x 281 x 292 h mm, capacity 47l.
- Stability of a floating body consisting of:
- Metric rule to measure the free water surface.
- Devices to support the balance.
- 2 floating profiles of different shape (with related panels for attachment to the balance).
- Metacentric height Centre of pressure consisting.
- Float (to put into the plexiglass container).
- Mobile set of weights which can be mouved laterally and longitudinally, in order to vary the inclination detected by an appropriate metering knob on a calibrated scale.
