We are driven by our pursuit to innovate, simplify, secure, and connect every station owner to their fuel management system. EVO™ 550 and EVO™ 5000 ATGs feature simple setup and operation, remote connectivity, and advanced security features to protect your fuel system while keeping you directly connected to vital site data whenever, and wherever.

Highly Capable

Make informed, data-driven inventory management decisions with features like, inventory monitoring, tank testing, containment compliance monitoring, and get expanded leak detection and containment monitoring capabilities.

Simple Interface

A full-color 7” LCD touchscreen serves up one of the most intuitive user interfaces available with simplified user features you won’t find anywhere else.

Secure Data

EVO™ Series ATGs keep your site in compliance and protected from security threats with customizable user roles, user activity tracking, and up to 3-years of data back-up to protect against power outages or other system interruptions.



Input Capacity

EVO™ 550 can support up to 36 sensors and 36 probes, while the EVO™ 5000 can support up to 72 sensors and 72 probes.


Turbine Pump Interface

Enhanced remote pump monitoring and control including pump-in-water automation, clogged intake escalation, tank leveling, and tank priority.


Remote Communication

The FFS PRO® Connect web interface allows users to securely connect directly to an EVO™ Series ATG from any web enabled device.


Inventory Reconciliation

Inventory Reconciliation is an automated leak detection function that analyzes tank volume, deliveries, and sales data to detect releases with a high level of accuracy.


Tank Autocalibration

Eliminate discrepancies in delivery reporting and daily reconciliations caused by inaccurate tank information programmed into the ATG with this function that automatically generates a highly accurate tank strapping chart.


Electronic Line Leak Detection

Electronic line leak detection (ELLD) learns the characteristics of each line, eliminating possible configuration errors and ensures unparalleled leak detection accuracy.


Secondary Containment Monitoring

Continuously monitor double-wall piping, tank, and sump interstitial spaces to detect any potential leaks in these double-wall containments.


DEF/AdBlue® Recirculation

Get automated control of your Diesel Exhaust Fluid (DEF) system while preventing frozen lines with energy and cost-saving recirculation functionality.

EVO™ Series ATGs help keep sites in compliance while providing marketers with the highest level protection from the security threats facing our industry.

EVO 600 TPI Wide.psd

Turbine Pump Interface is a powerful tool that creates a network between your Submersible Turbine Pump (STP) controllers and EVO™ Series ATGs. Through TPI, the tank gauge can be programmed to respond to faults in the submersible pumping system and react with intelligence that pump controllers alone cannot.


Pump In Water Automation

When the water level in a tank approaches the pump intake, the tank gauge will enter alarm mode and automatically shut down the pump, protecting the system and consumers from water being pumped from that tank.

Leveling & Priority Modes

When managing two storage tanks of the same product ‘Leveling Mode’ can keep both tanks at the same percentage full without the use of a syphon bar between the two tanks.

Remote Pump Interaction

By networking the intelligent controllers to the fuel management system via TPI, a technician can remotely connect to the site to review the logged event history and view the status.

EVO550 EVO5000 Advanced Wide.psd

EVO™ 550 and EVO™ 5000 ATGs offer additional advanced features and capabilites to manage your entire system as efficiently as possible.


AutoLearn™ Technology

Patented AutoLearn™ electronic line leak detection capability including Statistical Line Leak Detection for high throughput sites.

Corrosion Control™ System

Proactively monitor for and remove corrosion-causing water from your fuel system with system automation and monitoring powered by EVO™ 550 or EVO™ 5000 ATGs.

Streamlined Setup

Hardware auto-detection and wiring confirmation, multipoint tank charting, network printer auto-detection, and the ability to download and upload entire programming profiles from one ATG to another.

EVO Select Wide.psd

The EVO™ Series family of ATGs offers four different options with right-sized features to meet the requirements of your specific application, size, and compliance needs. Which ATG is right for your application?
