The Model 100 will accurately maintain the set flow rate in spite of fluctuating downstream pressure — even if the fluctuation is to within 10 psi of the supply pressure. When the flow controller is equipped with the optional Spectrol digital dial, settings are reproducible to better than 1%.

The Model 100 is available in a variety of preset maximum flow rates, from 150 mL/min to 10 liters/min (N2 at 40 psi). Any flow controller in this series can be equipped with a 10-turn Spectrol digital dial (3 or 4 digits), to permit a visual indication of the flow setting.

NOTE: With all our flow controllers, the inlet pressure must exceed the outlet pressure by 10 psi.
