• If the data collected is not formatted to use the maximum number of IDX
entries in the GUI, accuracy is jeopardized. For example, if independent testing
yields only 50 Roshko/Strouhal points (IDX linearization entries) the data will
not be as accurate as it would be by using all 100 points in the
Linearization table.
• Data tables interpolate between points.
• Data tables do not extrapolate beyond the minimum and maximum values.
The flow processor holds the last value in the table, if the threshold is
exceeded.
Flow processors with factory-created profiles have pre-formatted data in the cells
of each lookup table. Powerful software, in conjunction with highly repeatable
and accurate calibration systems, provides Badger Meter the ability to fit
accurate curves to calibration profiles. Using linear, exponential or logarithmic
interpolation, the flow computer can use and optimize the maximum number of
IDX entries.
