The module consists of a cylindrical tank with lateral transparent surfaces where a nozzle, connected to the Hydraulics Bench (FME00), is aligned with a device in which the problem surface is fitted. The vertical force made by the water against the surface is measured using calibrated weights that balance this force. Taking as a reference a gauge, which has been previously adjusted to a zero reference, we measure the force thanks to a mark that appears on the surface where the masses were placed.

Adjustable supports that let the device balance.

Holes made on the tank base in order to drain the water. In this way, splashes are avoided.
