Highest Performance,  Most Requested Mechanical Line Leak Detector Built Today!

The 99 LD-2000 is the most requested mechanical line leak detector built today. New engineering and the Vmι two year warranty (after installation) make the 99 LD-2000 more attractive to station operators today than ever before. Not only is the 99 LD-2000 less expensive to own, it is faster and less subject to field and line variables than ever before!

Integrated In-Line Check Valve / Pressure Relief

A leaking check valve in the turbine, defective submersible pump pressure relief, or a defective bypass valve will allow the line system to depressurize, resetting the leak detector. Drain-back into the tank and thermal contraction will cause vapor pockets to form. Vapor pockets increase the length of time it takes for a leak detector to open to full flow. Pump problems such as these result in slow flow and technical support calls. The resulting service costs and customer dissatisfaction all take away from the bottom line - making money.

In addition to the previously described submersible pump problems encountered without an in-line check valve, the metering portion of the leak detector is hammered by hydraulic shock. This results in leaks going undetected. Those leak detectors are just not equipped for the job you purchased them for.

The 99 LD-2000 is the answer you have been looking for. Vmι leak detectors, with an integrated check valve and pressure relief valve, will save money, reduce customer frustration at the dispenser and reduce service calls.

The 99 series leak detectors are the lowest profile leak detectors available today.

Higher Level of Performance

The 99 LD-2000 has a higher level of performance over a broader range of burial depth, line length, and piping system types than any other leak detector.

Additional Features

Increased Flow Capacity

The 99 LD-2000 shares the longest guarantee available in the industry, along with all other Vmι 99 LD-2000 series leak detectors and the 99 LD-3000 series leak detectors. For 24 months from date of installation, the 99 LD-2000 is guaranteed to see a 3 GPH leak @ 10 PSI.

Field Adjustable Leak Threshold

The One-Way Poppet Flow Path isolates pump turbulence from line leak detection at pump start-up. The hardened stainless steel poppet does not dimensionally change because of thermal conditions encountered during station operation (precision metering change is insignificant down to -20° F).

Reverse Ratio Piston / Poppet Combination

Reverse Ratio means the leak detector has a smaller diameter piston area than the poppet it is attached to. This smaller piston area keeps the leak detector in the fast fill position (3 GPM) to a higher line pressure while compressing vapor pockets and expanding flexible pipes faster. This means less time to full flow. The leak detector does not have to completely reset (as with competitive leak detectors) for the poppet to be forced into the reset mode at pump start-up.

Smaller Volume / Faster Response Piston Size

With a reduced piston size, there is one-fourth the fuel volume to replace when in leak search and one-fourth the fuel volume to return to the line when the pump turns off. This combination makes for a more responsive and faster leak detector. Less volume to leave the line for the leak detector to reset and catch leaks. Less volume to fill and provide full flow for dispensing!

Superior Flex-Pipe Performance

The reduced surface area of the piston significantly reduces the surface area exposed to hydraulic line shock. This results in enhanced performance with steel and fiberglass pipe, and especially with today’s flexible pipe.

99 LD-2000\E

In the early 1990’s, the first commercially successful flexible pipe, Total Containment PP-1500, was introduced to the U. S. petroleum industry. Due to the flexibility of this pipe system, no line leak detection would work. In 1992, the Vmι LD-2000\E was certified for 3 GPH @ 10 PSI on Total Containment PP-1500 pipe. The 99 LD-2000\E is still required for existing PP-1500 pipe. Additionally, today the 99 LD-2000\E is used in sites that have the same line characteristics as the LD-2000\E was originally certified for, even though the pipe is different. The original certification of the LD-2000\E concerned the bleed-back modulus of PP-1500 pipe. Today, lines with high bleed-back (generally above 600 ml.) and high head pressure may require the 99 LD-2000\E to pass a field test for annual certification. Consult with factory before ordering and installing the 99 LD-2000\E.

Electronic Line Leak Detection Upgrade!

The 99 LD-2000 may be upgraded in the field to eliminate thermal induced slow-flow, provide submersible shut-down, and alarm notification to site monitoring equipment. Request information on the ISM-4080, an easy upgrade for existing or new installations. The ISM-4080 also stages turbines and controls solenoid valves for loading racks and marine applications. If there is no need for staged turbines, solenoid valve control, alarm notification or submersible shut-down, request information on the ARM-4073 to eliminate false alarms only.
