This small TUBA 150 C tubular float level switches are equipped with a TEFLON cable and a specially designed PTFE housing for extremely aggressive liquids, such as for example sulfuric acid and very hot liquids reaching temperatures up to 150°C.

The TUBA 150 C tubular float level switches have a ball inside a sealed polypropylene cylinder that will activate a microswitch according to its position. This principle is extremely reliable.
The small diameter of this float (Ø 55 mm) allows its introduction by small holes often placed on the vertical walls of the tanks.

Emptying operation: The liquid reaches the float which by tilting gives the signal to the pump to start for emptying. Pumping allows to empty the liquid. The pumping stops as soon as the low regulator returns to the vertical position.

Filling operation: The filling starts as soon as the low regulator returns to the vertical position. The pump is used to fill the tank. The filling stops as soon as the high level regulator switches.
