EVO™ LLD

EVO™ LLD gives a site electronic line leak detection without a full tank gauge. It comes as a complete kit with its own console, a pressure transducer for each line, a needle valve kit and a 3.0 gph (11.4 lph) leak generator kit, ordered as EVO-LLDS/2, /3 or /4 for two, three or four lines. Every testing feature is included as standard, so there are no software options to add later.

Each transducer threads into the leak detector port of the submersible pump manifold. At setup, AUTO-LEARN® introduces a calibrated leak and records the pressure decay curve of that line, so the installer never types in pipe lengths or diameters. Because the learned values cannot be edited by hand, staff cannot alter setup data to clear an alarm.

In service the console runs a 3.0 gph gross test after every dispense cycle or 45 minutes and shuts down the pump if it fails. Precision tests run while line temperature is stable, at 0.2 gph once a month and 0.1 gph once a year, and Statistical Line Leak Detection (SLLD) gathers pressure data during normal trading so that busy sites with few quiet periods can still reach 0.2 gph precision. Alarms show on the console screen and can be pushed by email or SMS through PRO™ Connect.
