Primary VIF (Value Information Field)
The VIF codes contain both unit and scaling factor for the record value. The VIF codes for volume and flow will, as
far as possible, reflect the display reading in the water meter as regards unit, decimal point and number of
decimals.
Thus, the VIF codes for these data values will vary depending on the configuration of the flowIQ® 2101/3100.
The relevant VIF codes are listed in the table below.
