Non return valve TECMA

Our tank sensor is driven by the air pressure generated by the water level. It must be installed in the upper part of the tank with the rubber hose that enters the tank so that, when the level of the water increases reaching the rubber hose, the pressure switch effects the contact. The pressure switch, located outside the tank, is a normal on-off switch that, being electrically connected with the control panel of our WCs (grey/black cable), warns through a red led that the tank is nearly full (usually the led is green). The sensor may be used to commutate different alarms.
