In scuba diving, the scuba tank is the diver’s
life source. When diving with mixed gases, it is essential that the
diver can accurately sample the oxygen level before using the tank.
Nitrox Technologies Inc. (NTI), a California-based manufacturer of
air separation systems, was faced with the challenge of creating a
highly accurate, yet cost effective, flow restrictor for use in
their MAXO2 oxygen analyzer, used by divers the world over. They
found their solution in a Bird Precision fixed ruby orifice with a
diameter of 0.005”.
Needle valves are often used for flow
restriction in other industries, but can be dangerous or even deadly
in scuba applications because the rate of flow can be easily altered
by one user without another’s knowledge. Bird Precision created
for NTI a fixed ruby orifice that allowed for highly repeatable
flow. The orifice provides a precise flow rate through the oxygen
analyzer to insure stability and accuracy in the analysis of oxygen.
This inexpensive and safe solution solved NTI’s problem with
Bird Precision of Waltham, MA creates a wide
variety of orifices ranging in size from .0008” to .0350” that
can be produced in high volume with extreme accuracy. Their orifices
have been used in a variety of applications and industries in need
of flow restriction, including medical equipment and instruments,
OEM applications, aerospace equipment, transportation engines and
parts, and many others.
