Overfill Alarm Station

The Preferred Fil-A-Larm system is installed in conjunction with underground storage tanks and above ground main storage tanks. 

It is designed to be located near the tank fill terminal to notify of a potential overfill.  It triggers a high level alarm that alerts the filling operator that the tank is filled to its predetermined capacity.  When an overfill alarm occurs, the alarm bell sounds and the corresponding alarm light flashes. The bell is automatically silenced in 90 seconds or instantly silenced when the operator selects the “Alarm Silence” pushbutton.  The visual alarm is highly visible even in direct sunlight.  The enclosure top mounted flashing lamp is visible from 180°.  A “Test” pushbutton is provided to verify the operation of the flashing alarm light(s) and bell.  The alarm automatically resets when liquid level goes below the overfill alarm setpoint.  A digital display of tank volume is available.
