Preferred Utilities’ Vacuum Leak Detection Monitor (Model VLM-P) is the reliable choice for precise leak detection in critical fuel systems. Designed to monitor interstitial spaces in double-walled piping, enclosures, and tanks, it ensures early alerts—often before liquid is present—maximizing safety and system uptime.

At Preferred, we don’t just rest on success—we build on it. Our Vacuum Leak Detection Monitor has been a successful solution and we’re excited to announce a series of updates to make it even better. These enhancements reflect our commitment to investing in advanced technology and delivering the best to our customers.
