It was replaced <br />by sensor models 794380-208, 209 which are included on the NWGLDE list <br />**** See Glossary <br />***** This sensor is identified as an interstitial sensor, but will function properly in other containment areas such as containment sumps, <br />contained risers and other contained enclosures. This sensor must be installed at the lowest point of the containment enclosure to insure <br />early detection of liquids. <br />Specificity Results (in addition to above): <br />Activated: diesel, heating oil #2, water. <br />Evaluations determined these sensors' responses to the liquids shown above and those indicated in the following section. Biodiesel <br />blends B6 -B20 meeting ASTM D7647 and biodiesel B100 meeting ASTM D6751 would also produce an alarm if the sensor threshold is <br />exceeded. Responses to these fuels were not determined, but would be expected to be very similar to the diesel responses. <br />http://www.waterboards.ca.gov/water issues/programs/ust/leak_prevention/lg113/vendors/... 6/11/2012 <br />
