The Model 202 provides a user-variable span adjustment permitting it to be used for a variety of flow ranges. The flow range is infinitely adjustable from a minimum flow as small as 5.0 mL/min up to a maximum flow of 1.6 L/min (N2 at 40 psi). After the span is adjusted, the flow controller has a full 10 turns of resolution between zero flow and the maximum rate. When equipped with a Spectrol digital dial, settings are reproducible to better than 1%.

The Model 202 comes standard with 1/8" NPT female pipe threads. Adapters to go from pipe to 1/16" OD tubing are included. Other fittings are available.

All flow rates listed in the product number tables are based on N2 at 40 psi inlet pressure. Maximum inlet pressure is 200 psi
