Specificity Results (in addition to above):
Activated: n-hexane,
diesel, jet-A fuel, toluene, xylene(s), water.
Evaluations determined these sensors' responses to the liquids
shown above as well as those indicated in this 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:
Control panel models:
CPF 1, CPF 2, CPF 3, CPF 4 for liquid level sensors;
CPI 1D, CPI 1H, CPI 1N inventory
control for liquid level sensors and 1 tank;
CPD 1, CPD 2, CPD 4 for discriminating liquid level sensors;
CPI 4 inventory control for liquid level sensors and up to 4 tanks;
BOMC battery operated control cap for liquid level sensors;
CCF 1DA battery operated control cap for dry annulus monitoring;
CCF
2 battery operated control cap for hydrostatic reservoir monitoring.
