Test Results:

ILS-350, TLS-300 Series, TLS 350 Series, TLS-450 Series

TLS-4 8601 Series

(The TLS-4 8601 Series consists of the following derivatives: TLS-4, TLS-4B, TLS-4c, TLS-4i, and TLS-S1 consoles.)

Position Sensitive Sensor 794380-323	unleaded gasoline	diesel*	water	E85
Threshold Level (inches)	1.44	1.38	1.36	**
Precision - Standard Deviation (inches)	0.003	0.006	0.004	**
Detection Time (minute)	<1	<1	<1	**
Fall Time (minute)	<1	<1	<1	**

*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.

**TLS-4 Series testing did not include testing with E-85 fuel. Evaluator expects comparable results from previous testing with other consoles listed

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.

Evaluations determined that the 794380-323 sensor responds to 100% Lubrizol Ultrazol 9888. Alarm and response can be expected to be very similar to the response values listed above.
