Liberty Overfill Prevention Systems

Security During Loading and Unloading Procedures

The OPWFTG Civacon Liberty

The OPWFTG Civacon Liberty overfill prevention system is designed for tank trucks, tank-truck loading stations (for top and bottom loading), storage depots and service stations. In the event of a possible overfill situation sensed by the Liberty sensors, the Liberty rack monitors output relay will send a signal to a terminal automation system, control valve, or pump, to shutdown the loading operation.

The Liberty

The Liberty failsafe and self-checking electronic sensors are available as 2-wire Thermistor, 2-wire quick start Optic, or 5-wire Optic. The Liberty on-board control monitors, with diagnostic display, offer 2-wire and 5-wire optic sensor compatibility with all other brands of rack monitors.

The ROM

The ROM on-board system combines overfill with retain feature of detecting presence of liquid in a compartment prior to loading. All on-board monitors can also be used as stand-alone truck system to close down tank-truck bottom valves in case of an overfull situation. The Liberty system conforms to Atex, Cenelec, and EN standards.
