1 OVERVIEW

1.1 GASLOG System

The GASLOG System is a telemetry system designed to provide continuous monitoring of gas tank
installations. Tank level, meter reading, and other status information is transferred from the remote site to
the enterprise database according to a defined reporting schedule.

Sites communicate with a Server using the GSM mobile telephone network. The Server stores the site
information in an industry standard SQL database that can easily be integrated into other processes in
the supply chain.

The GASLOG system is highly scalable and capable of handling hundreds of thousands of customers,
sites and tanks.

GASLOG System Architecture

1.2 GASLOG Site Equipment

Each GASLOG cellular site consists of two primary components:

• SC414 Cellular Dialer. Connects to sensors and performs data logging and Server communications
via a cellular network.

• Sensor(s). Senders provide locally wired tank level information for the SC414 Cellular Dialer.
