First, check that the meter was not zeroed with a full line. Second, the meter may not have been installed properly (e.g. piping flanges were not aligned or spaced properly). Also, there could be an incorrect flow cal factor. If it is an older meter (from the 1980s) piping, harmonic distortion and excessive vibration could be the cause. Also bad coils or magnets are possible.
