Leakage control system for buried tanks

Accessories and spare parts

Safety system mod. LAG14ER, complete with control unit, antistatic plastic tank, two-electrode probe, assembly set. The system exploits the conductive property of water and by the two electrodes of the probe, set in the tank, it activates the possible alarm circuit.

The controller controls the probe; when a loss occurs, the liquid level in the tank decreases and, since they are no longer submerged in the liquid, the electrodes change their potential. This change is detected by the control unit and it activates the optical-acoustic alarm circuit.
