EVO™ 550 & EVO™ 5000

EVO™ 550 & EVO™ 5000 Automatic Tank Gauges (ATGs) provide highly accurate inventory management and full-featured compliance monitoring for any size fuel system.





These module-based ATGs are highly configurable for site-specific probe and sensor requirements. Their simple setup and operation, remote connectivity, and advanced security features protect your fuel system while keeping you directly connected to vital site data whenever, and wherever. The highly-intuitive, full-color, icon-based touch screen provides user-friendly on-site access to inventory, alarm, and compliance data.


  • Allows you to make informed, data-driven inventory management decisions while keeping your site in compliance and protected from security threats.
  • Provides inventory monitoring, static and continuous tank testing, tank autocalibration, inventory reconciliation, and containment compliance monitoring.
  • With the EVO™ 550, six total modules can be installed with a maximum of four intrinsically safe modules and a maximum of three of any one kind of module. With the EVO™ 5000, eleven total modules can be installed with a maximum of nine intrinsically safe modules and a maximum of three of any one kind of module.


  • Patented AutoLearn™ electronic line leak detection capability including Statistical Line Leak Detection for high throughput sites.
  • Secondary containment monitoring provides the ability to vacuum-monitor single or multiple secondary containment spaces like double walled tanks, piping, and sumps.
  • Streamlined setup and programming includes 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.


  • Intuitive full-color 7” touch screen interface provides simplified on-site access features including:
  • One Touch buttons that are custom programmed to carry out common automated tasks with a single tap.
  • Quick Jump menu allows you to quickly maneuver from application to application using a single button.
  • Programmable product colors.


  • Available with optional 24 hour statistical continuous automatic leak detection (SCALD) and the industry’s only Turbine Pump Interface (TPI) capability for enhanced and automated submersible turbine pump control.
  • Web interface allows you to directly connect to your ATG from any web enabled device.

Order Info

Ordering Guide

ATG model, software and hardware options can be listed separately or combined when ordering. Systems shipped from the factory will list the combined part number. Complete part numbers have a specific order and are created using the following guidelines:


  • TX = Base Model Options
    • T550E = EVO™ 550 base ATG
    • T5000E = EVO™ 5000 base ATG
  • DPMIE = Hardware Options (choose all that apply)*
    • D = Display
    • P = Printer
    • M = Internal modem
    • I = Dispenser interface module
    • E = LON module
  • TRLGSC = Software Options (choose all that apply)
    • T = SCALD 24-hour tank testing
    • R = Reconciliation/Autocalibration
    • L = Line leak detection
    • G = Line leak detection for generator applications**
    • S = Secondary containment monitoring
    • C = Recirculation, scheduling, and timer conditions
  • *Only one EVO-DIM or EVO-LON module can be installed per ATG.
  • **For use only with generator applications, always follow regulatory requirements.
  • Example: T550EDPMI/TRLS = EVO™ 550 base model with display, with printer, with internal modem, with dispenser interface module, with SCALD, with reconciliation/autocalibration, with line leak detection, and with secondary containment monitoring.
