Model 202 gas flow controller Adjustable span upstream-referenced flow controller
The Model 202 provides a user-variable span adjustment
permitting it to be used for a variety of flow ranges. After
the span is adjusted, the flow controller has a full 10 turns of
resolution between the minimum and maximum flow rates.
When equipped with a Spectrol digital dial, settings are
reproducible to better than 1%.

Model 300 gas flow controller Fixed span downstream-referenced flow controller
The Model 300 flow controller provides a stable flow rate
when upstream pressure conditions vary, providing the
downstream pressure remains constant.
All flow rates listed below are based on N2 at 40 psi inlet
pressure. Maximum inlet pressure is 200 psi.
