If all above steps are completed, typical accuracy values of flow sensor readings are
approximately within 1%.
Flow Sensor Oset and K Values
Each flow meter installation must include entry of the "offset" value and "K" values
for proper calibration of the meter. The DXi controller supports the complete line
of Toro and Irritrol-branded flow sensor (DI & CST). Flow Sensors may be either
conventional and/or decoder type. The controller can only have 3 in total.
