For a flow range of 20-200ml/min:
At 200ml/min the output signal would be 20mA
If the output signal were 9mA then the flow rate would be:
200 ÷ (20-4) × 9 = 112.5ml/min

Units With an Integral Display
The FLR 1000-D, FLR 1000-BR-D and FLR 1000-ST-D series features an
integral 3 ½ digit LCD display. This is configured to read in ml/min for flow
ranges up to 50-500 ml/min and in l/min for flow ranges of 0.1 – 1.0
L/min. The display will only operate if power is applied to the unit.
Flow readings may be taken directly from the display or by monitoring the
0-5VDC analog output provided by using a cable assembly or power
adapter package (see above).

Operating at Flow Rates Outside the Calibrated Flow Range
CAUTION: If the flow through the unit exceeds 120% of
the maximum rated (full scale) flow the unit may be
damaged. This type of damage will not be repaired under
warranty.
Flow measurement is only accurate within the calibrated flow range for the
unit. This is detailed on the calibration certificate. The unit will still
operate, to some degree, outside this flow range.
Results obtained when operating outside the specified range of the unit
are not accurate but may be considered repeatable.
