  • Method and apparatus for detection of phase separation in storage tanks
    Patent number: 9945712
    Abstract: A system and method for detecting phase separation in storage tanks is provided. At least one float has a density calibrated to detect a density differential among surrounding fluids. The float is buoyant on a relatively more dense lower layer of fluid such as phase separated fuel or pure water, while remaining submerged in a relatively less dense upper layer of fluid such as a gasoline/ethanol blend. A detection device sends a signal when the float rises or falls above or below a preset acceptable level.
    Type: Grant
    Filed: September 2, 2014
    Date of Patent: April 17, 2018
    Assignee: Franklin Fueling Systems, LLC
    Inventors: Donald P. Kenney, David R. Kruschke
