Model 202 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. 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.
