Abstract
A remotely controllable apparatus, system and method for monitoring, inventory, controlling and reporting on the filling, refilling and dispensing of Liquified Natural Gas (LNG) at portable temporary or semi-permanent field-located storage and dispensing stations, including a portable storage tank, and an associated portable pump and control skid, which skid includes: an on-site microprocessor control system having: security features; pump, fill and dispense connections; an LNG leak detection system; a communications link (typically an RF cellular phone system) to a host computer; a dispensing and refilling sales authorization and initiation system (typically a card reader of the credit, access or proximity card types); and a remotely located host computer having a full suite of features including: inventory, monitoring, security and access control; operational control; financial and transaction record keeping and report generation; and emergency warning and shut-down. The field control unit control functions are performed by the on-site microprocessor which receives input from a plurality of natural gas leak detection sensors, and provides complete on site security screening, data…
