Vacuum Leak Detection System

Overview | Features and Specifications

The advanced Vacuum Leak Detection System continuously monitors the interstitial area around double-walled piping, enclosures, tank walls, etc. The controller creates a vacuum in the interstitial space and if it senses a significant pressure drop for a specific amount of time, the controller alerts the operator of a leak. The system also alerts the operator to whether the leak is oil or water. Vacuum leak detection gives significant benefits of early alerts even before liquid is present.

  • Safe for outdoors, built in a NEMA 4X cabinet enclosure.
  • Separated monitored zones means a leak in one zone does not affect the monitoring of other zones.
  • Simple and quick mounting.
  • UL 508 standard.
  • Standard 4" touch screen showing overview, alarm, and commissioning.
  • Standard Modbus Ethernet and BacNet IP communication.
  • Integrates discriminating point leak detection with the vacuum leak detection.

  • Overview
  •  

The vacuum leak detection monitoring systems can be used on double-walled piping, enclosures, sumps, tank walls, etc. The controller monitors up to four underpressure zones that monitor the space. When pressure loss change is sensed in one of the zones for a specified time, the controller alerts the operator of a leak in that zone. The vacuum leak detection system signals early leak detection even before a liquid is present to set off an alarm.
