EVO™ SERIES
ELECTRONIC LINE
LEAK DETECTION
EVO™ Series Electronic Line Leak Detection (ELLD) is
designed to provide early detection of leaks in pressurized
fuel lines. The system features automatic submersible pump
shutdown in the event of a leak, minimizing the risks of costly
spills and environmental cleanup. This pressure-based
system utilizes learned line characteristics learned to monitor
for changes in pressure to declare the line as tight or
determine if a leak is present.
HIGHLIGHTS
• Optional software feature of EVO™ 600 and EVO™ 6000.
• Remote access to line pressure, test, and alarm information.
• Utilizes pressure transducer installed in the submersible pump.
• Dispenser Hook Isolation (DHI) and Turbine Pump
Interface™ (TPI) pump control options.
• Compatible with submersible pumps generating 25 psi or more.
• Automatically learns the pressure characteristics of each line.
• Automated 3 gph (11 lph), 0.2 gph (0.8 lph), and 0.1 gph
(0.4 lph) compliance testing.
• Performs a 3 gph leak and pressure test after every dispense
cycle or 45 min. Positive shutdown of the pump on test failure.
• Performs a 0.2 gph monthly and 0.1 gph annual precision leak
test during the thermally stable periods of dispensing. Optional
positive shutdown of the pump on test failure.
• Positive pump shutdown in the event of a gross leak (can be
disabled for generator applications), optional for monthly and
annual precision testing.
• Performs pressure up, catch pressure, other additional checks.
• Compatible with flexible, steel, fiberglass, or combination of pipe.

•1
The EVO™ Pressure Transducer is typically installed in the
leak detector port of the submersible pump manifold.
During the AUTO-LEARN® setup process, EVO™ learns the
pressure decay curve characteristics of a calibrated leak.
•2
During non-pumping periods, the EVO™ will conduct line
leak testing by comparing the line pressure changes to
those learned during the AUTO-LEARN® process. A
deviation in pressure, such as a drop beyond predefined
thresholds, will be declared as a leak and shut down the
associated submersible pump.
•3
With declaration of a leak, the system will notify the
operator via the EVO™ display with additional email or
SMS notification through the FFS PRO® Connect Web
Browser Interface.
• EVO™ leverages AUTO-LEARN® technology to automatically
program the unique pressure characteristics of each
pipework system. This ensures precise, customized leak
detection, reducing the risk of false alarms and enhancing
overall system accuracy.
• With Statistical Line Leak Detection (SLLD), EVO™ allows
sites with constant fuel flow to perform 0.2 gph leak testing
even during peak operation. This is ideal for busy fuel
stations where quiet periods are rare, ensuring continuous
compliance without disrupting operations.
• EVO™ streamlines the regulatory process by automating
3 gph, 0.2 gph, and 0.1 gph line leak detection
compliance testing. This feature ensures that your system
meets environmental standards effortlessly, with the
EVO™ automatically performing the necessary tests at
regular intervals.
