Liquid leak detector LAG 14 ER

for industryfor storage tanks

LAG 14 ER is a class II (EN 13160-1:2003) leak detector with an intrinsically safe probe circuit for the monitoring of double skin tanks through a conductive fluid in the interstitial space between the skins. This system is composed of a control unit, a tank for leak monitoring fluid and a probe. LAG 14 ER can be installed on tanks which contain flammable liquids, non-flammable liquids or explosives - class AI, AII, AIII and B (Ref. VbF. Flammable liquids regulation). The control unit is connected through tubing inserted in the interstitial space of the tank and constantly monitors the seal of both internal and external wall of the tank. The liquid used to fill the interstitial and the control unit drip tray is propylene glycol (30% of the interstitial space), miscible with water for the complete filling. Operating principle: The system exploits the conductive properties of the detector fluid in which two electrodes are immersed and are responsible for the activation of the alarm circuit without any mechanical movement. The control unit constantly monitors the potential between the electrodes immersed in the liquid. In case of leak in the interstitial space, the liquid level in the tank lowers, changing the potential of the electrodes and, consequently, setting off the alarms, acoustic and optical. The alarms can be local, integrated in the system, and, where installed, remote via relay. The tank container LAG, made of permanent antistatic plastic material, can be installed in explosive zone. The electronic control unit cannot be installed in zones classified EX. A single control unit is able to monitor several tanks.
