The Non-Discriminating Interstitial Sensor for double-wall fiberglass tanks detects the presence of liquid in the interstitial space of the tank.
The Veeder-Root Interstitial Sensor detects the presence of liquid between the double wall of fiberglass tanks. Liquid triggers an alarm signal to your automatic tank gauge. You’ll know immediately where the problem is so you can take action to prevent serious and costly safety and environmental problems.
