*The evaluation determined these sensors' responses to the liquids shown above and those indicated in the following section.  Biodiesel blends B6-B20 meeting ASTM D7467 and biodiesel B100 meeting ASTM D6751 would also produce an alarm if the sensor threshold is exceeded.  Responses to these fuels were not determined, but would be expected to be very similar to the diesel responses.

Specificity Results:
Evaluator reports this sensor will respond to any liquid once sensor’s threshold level has been exceeded.
This testing included water, diesel fuel, gasoline, and E85.

Manufacturer’s Specifications:
Sensor is reusable.

Comments:
Sensor will alarm if it is raised from the bottom of the containment vessel.
Comparison of TLS-450 with TLS-350 series console showed comparable results when evaluated with representative sensors.

This sensor is identified as an interstitial sensor, but will function properly in other containment areas such as containment sumps, contained risers and other contained enclosures.  This sensor must be installed at the lowest point of the containment enclosure to insure early detection of liquids.
