*Evaluations determined these sensors' responses to the
liquids shown above. Biodiesel blends B6-B20 meeting ASTM D7647 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
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:
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.
