Programmable fuel dispensing system

摘要

A centralized fuel or fuel monitoring, control and dispensing system operating under the control of a modern solid state programmable logic controller (PLC) that provides control options with capabilities far exceeding those available from relay logic systems. The system also incorporates compliance with the latest EPA mandates by accepting inputs from water and gasoline sensors that monitor the condition of the required "tank within a tank" dual storage tanks. If a fault condition is detected, the system will force a safety shutdown in the affected part of the installation. The PLC provides centralized monitoring, controlling and reporting functions to the operators of fuel dispensing operations such as self-service gas station complexes and fuel depots. Remote monitoring and programming of the PLC is provided by an internal modem through any available communications link.
