Miscellaneous
Flow Rate Calculations The flow meter creates a table of level-versus-flow rate from program selections;
this table divides the level span into 256 equally-spaced level increments. Each
level increment corresponds to a specific flow rate. During data collection, if the
measured level falls between two table values, the flow meter will perform a linear
interpolation to calculate the flow rate value.
