The principle of functioning of this float level switch is very easy to understand, when the level of the liquid has reached the float level switch, the float tilts and a contact with a circuit connected to an electrical panel will be established. 

Then, the arrival of the liquid will be closed or opened. But sometimes, tanks or containers have a narrow opening and it is very difficullt to access inside. Tuba range products have been conceived to fit every openings even the more restricted access. Indeed they have a very small diameter.  Tuba can be installed in different ways : vertically suspended, with external ballasts or horizontally mounted to the tank side.

ATMI is specialized in water and solid regulation systems. Two model of Tuba range are available : the TUBA 1” and the TUBA 1” 1/4
