*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.
**See
glossary.
Specificity:
Evaluator claims RE400-179-5 to
RE400-199-5 Combination High Level/Low Level Sensor and RE400-042-5 Hydrostatic
Sensor will respond to any liquid once threshold has been exceeded.
Comments:
RE400-179-5 to RE400-199-5
Combination High Level/Low Level Sensor model numbers and high level detection
limit vary with length of sensor.
PPM 4000 with Optical Liquid Discrimination Sensor evaluation lists all PPM, RLM,
and ST models, including the Multiplexer Unit.
However, evaluation procedures were performed using model PPM 4000.
Sensors
are reusable.
