 Back flow detection period: this period is a multiple of the “Reading Sampling Period”
parameter. Indicates the water back flow measurement granularity.
 Back flow Threshold : water back flow rate (same unit as encoder).
 Number of back flow presence before detection: this parameter is used to filter the number of
back flow presence before real detection.
 Back flow detection flags : this word contains 12 relevant bits that express back flow detection
in the month.
