Interstitial Sensor for Steel Tanks
The Interstitial Sensor for steel tanks is non-discriminating and detects the presence of liquid between the double walls of the tank.
Detect dangerous leaks in double-walled steel tanks. The presence of liquid in the interstitial space of double-walled tanks triggers an alarm in your automatic tank gauge console. The visual and audible alarm notifies you immediately of the problem, so you take quick and efficient action to help prevent safety and environmental issues. The console can also trigger an on-site alarm for even greater warning capability.
