Interstitial Sensor for Fiberglass Tanks

Our products offer the following features and benefits:

Veeder-Root's Interstitial Sensor for use in Fiberglass Tanks detects the presence of liquid in the interstitial space of a double-wall fiberglass tank. Liquid in the annulus could mean a dangerous leak. When liquid is detected, the sensor sends an alarm signal to a TLS-350R, TLS-350, TLS-350J, ILS-350, TLS-300i, TLS-300C, TLS-250i, or ILS-250 monitor. The monitor's visual and audible built-in alarm indicators immediately tell you where the problem is, so you can quickly take action to help prevent serious safety and environmental problems.

The Veeder-Root Interstitial Sensor for fiberglass tanks can be used in the annulus of the fiberglass tank with a riser pipe of 4". Only two wires are required to connect the sensor to a TLS or ILS system.

Positive alarm indication of any liquid in double-wall fiberglass tanks
System indicators pinpoint alarm location
Fast action helps prevent serious safety and environmental problems.

Features

The presence of any liquid in the tank's interstitial space triggers a Fuel Alarm.
