12.3 Flow Restrictors and Regulators

A variety of Flow Restrictors and Pressure Regulators
for the Sample Flow Method are available from Nuvair,
all calibrated to produce a flow rate of 1 – 5 L/min with
a Regulator output of 100 – 160 psi.

Universal Flow Restrictors are used for most
applications and are typically provided complete with
Regulator.

When analyzing Scuba Cylinder gases, special Flow
Restrictors can be used to obtain the sample gas
directly from the BC inflator hose. A variety of BC
Flow Restrictors are available to fit the different types
of inflator hose QD fittings used.
