Model 327 Volumetric Line Leak Detector (VLLD)

While pressure may have its place in many fuel-related applications, it’s performance in line-leak detection has been found less than reliable. Rising to the challenge of finding a more reliable solution, OPW Fuel Management Systems offers the Model 327 Volumetric Line Leak Detector (VLLD). The VLLD has been designed to use a highly accurate flow sensor, rather than less-reliable pressure decay methods, to measure the product line’s leak rate. In turn, VLLD provides a more accurate measure of the actual product volume that is being lost.  

The Model 327 VLLD has been designed to detect a leak in the pressurized product pipe by utilizing the submersible turbine pump (STP) in order to monitor volume changes in the product piping when no one is dispensing fuel. The OPW VLLD utilizes an internal flow sensor to detect and measure any volume changes in the product pipe and will initiate an alarm condition if an actual leak is detected. Constructed from hardened anodized aluminum, the rugged Model 327 VLLD is easy to install in the 2-inch (5.1 cm) leak-detector port found on the submersible turbine pump (STP).

Utilizing a highly accurate flow sensor, the VLLD provides an industry-leading method for detecting and measuring leaks in fuel lines. The VLLD can test volumes for pipes measuring from 1.5 inches to 4 inches in diameter, and can monitor rigid pipe, flexible pipe or a combination of both, making it the ideal leak detection solution for any site configuration.
