The present application is related to U.S. patent application Ser. No. 11/210,715, filed on Aug. 24, 2005; which is a continuation patent application of U.S. patent application Ser. No. 10/935,024, now U.S. Pat. No. 6,964,283, filed on Sep. 7, 2004; which is a continuation patent application of U.S. patent application Ser. No. 10/180,047, now U.S. Pat. No. 6,802,344, filed on Jun. 27, 2002; which is a divisional patent application of U.S. Pat. No. 6,622,757, filed on Nov. 30, 2000, entitled �Fueling System Vapor Recovery And Containment Performance Monitor And Method Of Operation Thereof;� all of which are entitled to the benefit of the earlier filing date and priority of U.S. Provisional Patent Application Ser. No. 60/168,029, filed on Nov. 30, 1999, entitled �Fueling System Vapor Recovery Performance Monitor,� U.S. Provisional Patent Application Ser. No. 60/202,054, filed on May 5, 2000, entitled �Fueling System Vapor Recovery Performance Monitor,� and U.S. Provisional Patent Application Ser. No. 60/202,659, filed on May 8, 2000, entitled �Method of Determining Failure of Fuel Vapor Recovery System.�
The maxPosVaporPumpAdj determines what adjustment to the vapor pump 222 can be made such that the total VaporCollected does not exceed the totalLiquidDispensed within a safety range for a given maxA-L. For the �Grade A� example, the maxPosVaporPumpAdj is equal to 3.19 gal./min., meaning that a maximum vapor pump 222 adjustment to increase the recovery of vapor at a rate of 3.19 gal./min. can be made without putting the system outside the operating safety range. If the maxPosVaporPumpAdj is greater than zero, this means that the vapor pump 222 is not already beyond its maximum adjustment and can be adjusted further. If the maxPosVaporPumpAdj is less than or equal to zero, this means that the vapor pump 222 is already beyond the maximum adjustment and no further adjustment can be made to increase the recovery of vapor without exceeding safety limits.
For the �Grade A� example, the maxNegVaporPumpAdj is equal to 2.34 gal./min. If the maxNegVaporPumpAdj is greater than zero, the vapor pump 222 is already beyond its maximum negative adjustment and cannot be adjusted further. Since the maxNegVaporPumpAdj is 2.34 gal./min., no negative adjustment to the vapor pump 222 is possible without the system exceeding the bounds of the prescribed safety range.
