  • SMART WIRELESS FUEL SYSTEM MONITOR INTEGRATED INTO A FUEL FILTER ASSEMBLY T-HANDLE
    Publication number: 20190358567
    Abstract: A device and method for determining a filter element is approaching an end of life obtains vacuum data corresponding to a vacuum at a filter element, and concludes the filter element is approaching an end of life based on the vacuum data as it relates to time in service. The end of life of the filter element may be based on detection of a knee in a vacuum curve derived from the vacuum data, high and low vacuum measurements over a specific time period deviating from one another by more than a prescribed amount, or high and low vacuum curves derived from the vacuum data trending apart from one another by more than a prescribed amount.
