Specificity Results
This evaluation determined the sensor's 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.
Manufacturer's Specifications
Manufacturer states that systems require no calibration.
Annual functional test required
Comments
Sensors are reusable.
Franklin Fueling Systems requires their own manufacturer certification for sensor installation and maintenance. Previous manufacturer certifications are not allowed, even if certification is current.
