What should facilities do if the calibration error for fuel flow meters that exceeds the 5.0 % performance specification?
For a fuel flow meter that either has not met, or may not be able to meet the 5.0% calibration error specification, the “best available monitoring method” (BAMM) may be used until April 1, 2010. You may request to use the BAMM through the remainder of 2010, as described in ยง98.3(d). However, for a fuel flow meter that cannot meet the calibration specification, the meter must either be replaced or modified to meet the specification by the time that the allowable use of the BAMM has expired.
