Test Results
Interstitial Sensor 794380-345
| Unleaded Gasoline | Diesel* | Water | E85 | |
|---|---|---|---|---|
| Detection time (min) | <1 | <1 | <1 | <1 |

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.)
| Unleaded Gasoline | Diesel* | Water | E85 | |
|---|---|---|---|---|
| Threshold Level (inches) | 0.148 | .1276 | 0.1482 | ** |
| Precision - Standard Deviation (inches) | 0.005 | 0.005 | 0.007 | ** |
| Detection Time (minute) | <0.1 | <0.1 | <0.1 | ** |
| Fall Time (minute) | <0.1 | <0.1 | <0.1 | ** |
*Evaluations determined these sensors' responses to the liquids shown above. 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 claims sensor will respond in any liquid after the sensor threshold is exceeded. This testing included water, diesel fuel, gasoline, and E85.
Manufacturer's specifications
Leak Tracer Dye develops color in alcohols, ketones, solvents, and PCBs as well as petroleum products.
Comments
Sensor can be removed, cleaned, and reinstalled, for periodic testing, if an alarm is triggered or if service is necessary.
Sensor has no moving parts.
Sensor is designed for use in the interstitial space of double-wall fiberglass tanks. When product or an open sensor (referred to as "Sensor Out") is detected, an audible alarm is actuated, a message is displayed on the TLS-350 or TLS-350R console, and a printed message is generated if the console is equipped with a printer. The alarms are also recorded as part of the TLS-350 or TLS-350R "Alarm History Report".
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.
