TMS3000 collage Whether you’re managing a nationwide network of convenience stores or a single site, the TMS3000 streamlines the entire inventory collection and management process, while assuring EPA compliance. The system has been designed with a distributed architecture that allows for tremendous flexibility in configuring the system for your particular application.

The TMS3000 system has the ability to transmit live data as well as a wide variety of inventory and log information to an on-site PC via RS-232, via optional internal modem to a centralized location, or from a LAN/WAN via optional, secured, internal network interface card. Additionally, hard copy reports can be directed to an internal printer. Log data includes Shift Inventory, unsupervised deliveries, bulk sales, alarms, leak test, water removal, product ordering, and thefts.

  • The TMS3000 system is easy to install and use. System set-up can be performed using the front panel push buttons, or, via the RS-232, modem port, or TCP/IP.


System operation is logical and simple to use. In the VIEW mode, a single push button selects the display of product level, gross or net volume, percent volume, water level, or product temperature. A second push button selects the displayed tank, or enables the AUTO SCAN mode, which cycles through and presents data for each active tank for five seconds. The third push button is used to initiate an on-demand SYSTEM TEST. Various menus and sub-menus are also available via these same push buttons while in the ACCESS mode, including LOG, LEAK, CONFIG, CLOCK and SYSTEM INITIALIZATION.

For UST applications, the TMS3000 is a high precision Automatic Tank Gauge that provides advanced leak sensing capabilities which meet or exceed EPA 0.1 or 0.2 GPH requirements for in-tank leaks up to 75,000 gallon with a probability of detection of better than 97%, using high accuracy magnetostrictive level probes. The TMS3000 has also been designed to generate inventory management files in formats well suited for movement into Statistical Inventory Reconciliation (SIR) platforms.

For AST applications, the TMS3000’s large, super bright day/night readable display, oversized push buttons for gloved operation, and weatherproof enclosure option allow the bulk delivery vehicle driver/operator to view real-time, accurate inventory data right at the loading rack. Or, if preferred, the TMS can be located in the office with TMS peripheral remote display and/or annunciator panels located outdoors. The TMS3000’s 12 tank capacity means only one system is required for most AST installations. The system can provide external audible and visual overfill warnings and alarms, as well as control pumps or electrically activated valves, thereby avoiding costly overfill clean-ups.
