***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.
**** Liquid Sensor for Sumps 794390-206 is no longer manufactured and is
not supported by the TLS-450 series console. It was replaced by sensor
models 794380-208, 209 which are included on the NWGLDE list.
*****See glossary.
Specificity Results (in addition to above):
Activated:
diesel, heating oil #2, water.
Evaluations 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.
Comments:
Comparison of TLS-450 Series console with TLS-350 series console
showed comparable results when evaluated with representative sensors in water
and diesel fuel.
Sensors are reusable.
Veeder-Root has redesigned sensor model 794390-409. The cable length remains the same (284”). The original design of the sensor has mesh netting around the sensor. The new design does not have mesh netting around the sensor. The old sensor parameters are as shown above. The redesigned sensor is listed under Veeder Root 8601 Series, 8600 Series, and TLS-3xx Series with Interstitial Liquid Sensor for Fiberglass Tanks 794390-409 interstitial Detector (Liquid Phase).
