Figure 4.28—Two options for conguring a 4-20 mA output
Flow rates in-between the minimum and maximum rate setpoints will result in an output of current between
4 mA and 20 mA according to the following calculation:

Where:
I
OUT
= output current
I
MAX
= maximum current output (20 mA)
I
MIN
= minimum current output (4 mA)
High = programmed ow rate that produces a 20-mA output
Low = programmed ow rate that produces a 4-mA output
