Automatic Tank Gauges
EVO™ 200 & EVO™ 400
EVO™ 200 & EVO™ 400 Automatic Tank Gauges (ATGs) provide highly accurate inventory management and containment monitoring for small to mid-size fuel systems.
NEVER STOP EVOLVING
We are driven by our pursuit to innovate, simplify, secure, and connect every station owner to their fuel management system. EVO™ 200 and EVO™ 400 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
EVO™ 200 and EVO™ 400 allow you to make informed, data-driven inventory management decisions with features like, inventory monitoring, tank testing, and containment compliance monitoring.
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.
TECHNICAL ADVANTAGES
Input CapacityEVO™ 200 can support any combination of up to 6 sensors and probes, while the EVO™ 400 can support any combination of up to 14 sensors and probes. | Turbine Pump InterfaceEnhanced remote pump monitoring and control including pump-in-water automation, clogged intake escalation, tank leveling, and tank priority. |
Remote CommunicationThe FFS PRO™ Connect web interface allows users to securely connect directly to an EVO™ Series ATG from any web enabled device. | Inventory ReconciliationInventory Reconciliation is an automated leak detection function that analyzes tank volume, deliveries, and sales data to detect fuel loss or gains with a high level of accuracy. |
Tank AutocalibrationEliminate 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. | NEW: Flow Rate MonitoringDetect and react to potential slow flow issues with automated daily reporting and alarms, helping to improve flow rates and dispenser throughput. |

SIMPLICITY & VISIBILITY
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. You choose your home screen, you program your product colors, and you choose what shows up on your Favorites screen. Customize the interface to meet your business needs the way you operate. Check out the interactive demo below.

SYSTEM SECURITY
EVO™ Series ATGs help keep sites in compliance while providing marketers with the highest level protection from the security threats facing our industry.
User Roles
Customizable user roles and log-in security protect against unwanted access and track user activity.
Data Back-Up
Stores up to 3-years of data to provide back up security from power outages or other system interruptions.
Secure WiFi
Optional WiFi allows secure and protected onsite viewing of inventory levels for fuel delivery drivers.

REMOTE CONNECTIVITY
The FFS PRO® Connect web interface allows you to securely connect directly to your EVO™ Series ATG from any web enabled device. It automatically scales for tablets and smart phones, meaning no app to download.

FFS PRO® CONNECT
FFS PRO® Connect displays real-time data allowing precise delivery scheduling and efficient site management. It also provide immediate notification of alarms so quick corrective actions can be taken.
Centralized Control
Provides centralized control of all compliance information – such as tank testing data and leak detection sensor status.
Reporting
A wide variety of reports can be custom-scheduled, displayed, printed, or emailed at specific times.
Simplified Setup
Simplifies setup and programming with the ability to download specific sections or the entire configuration from one ATG to another.

TURBINE PUMP INTERFACE
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.

FLOW RATE MONITORING
Improve dispenser throughput and maintain fast flow rates with the ability to detect and react to potential slow flow issues before they impact business with Flow Rate Monitoring. Available as a software option on new EVO™ Series ATGs or as a field upgrade option, Flow Rate Monitoring delivers ongoing flow rate performance data, flow rates for each fueling point, and provides a notification if transactions dip below a user-defined set point.
Know Your Flow
Monitor for and ensure fast and consistent dispenser throughput with daily reports and alarm notifications regarding flow rate performance.
Performance Monitoring
Sales and dispensing duration data are automatically reconciled to help you better understand the flow performance of every fueling point.
Proactive Maintenance
Often, slow flow rates can indicate that a dispenser filter needs to be changed. Be proactive in calling for maintenance, getting dispensers back to peak performance sooner.
