HIS

Hydrostatic Interstitial

The HIS detects leaks in double wall tanks where the interstitial space is filled with a liquid brine solution. The polyester, Nitrile, and epoxy construction is compatible with all types of brine.

Hydrostatic Interstitial Sensor

  • Versatile sensor for virtually all fiberglass double wall
    tanks equipped for hydrostatic leak detection.
  • Microcomputer monitors liquid at varying levels within
    tanks and relays digitally encoded status information
    via the fail-safe sensor digital communication
    system to fuel management system or Tank Sentinel®
    ATGs, alerting of any alarm conditions.
  • For installation, lower the HIS to the bottom of the brine reservoir of double wall tank. The normal brine level should reside half way up the sensor. Sensors include the TSP-KV4 vented 4" riser cap.
