Interstitial Sensor for Steel Tanks

Our products offer the following features and benefits:

The Veeder-Root Interstitial Sensor for use in Steel Tanks detects the presence of liquid in the interstitial space of a double-wall steel 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, or TLS-300C 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 TLS-350R, TLS-350, TLS-350J, ILS-350, TLS-300i, TLS-300C, TLS-250i, and ILS-250 systems feature internal alarm relays that can also trigger on-site alarms for even greater warning capability. The TLS-350R, TLS-350, TLS-300i, and TLS-300C alarm signals from the sensor triggers a report showing the time and the location of the alarm condition. This information is stored in the system's alarm history and can be retrieved through the monitor's integral printer or remotely through its data communications interface.

The Veeder-Root Interstitial Sensor for Steel Tanks can used in the annulus of steel tanks with a sensor riser pipe 1.5" I.D. or greater. Only two wires are required to connect the sensor to a TLS or ILS system.
