Flow Reading Accuracy 

Since the Evolution DX2 controller has been designed to work 
directly with flow sensors, the accuracy of the actual readings 
are limited only by the flow sensor devices.  Typical accuracy 
values are approximately 1%. 

 
 
 

Flow Meter Offset and K Values 

Each flow meter installation must include entry of the "offset" 
value and "K" values for proper calibration of the meter.  Use the 
following table to determine the appropriate values for your 
installation.
