Parameters (= X)
qeh_pval Energy hour flow rate float 33101…33102
qe_yesterday Energy flow of the previous day float 33103…33104
avh_EXT Hourly average of the square root of the product of static pressure and
differential pressure. This is also the average uncorrected volume
(AGA7) for the hour. float 33105…33106
avd_EXT Daily average of the square root of the product of static pressure and
differential pressure. This is also the average uncorrected volume
(AGA7) for the day. float 33107…33108
avh_Gr Average real relative density for the hour float 33109…33110
avd_Gr Average real relative density for the day float 33111…33112
