100-500 ml/min and in l/min for flow ranges of 0.2 – 1.0 L/min and above. 

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. 

 

a) Flows Above the Maximum Rated Flow. 

 

If the flow rate is above the maximum rated (or full scale) flow, the unit 

will still operate and provide an output signal proportional to the flow rate.  
 

Flows must not exceed 120% of the maximum rated flow or the unit may 
be damaged. 

 

b) Flows Below the Minimum Rated Flow. 

 

Signal outputs may be obtained at flow rates below the minimum specified 
for your unit. The amount of flow that may be measured below the 

minimum specified varies from unit to unit.
