Flowmeter assemblies are designed to operate at an inlet pressure of 30 PSIG
(except H1105 which is designed to operate at an inlet pressure of 80 PSIG). They
may be attached to regulators or pipeline installations. All flowmeters have 1/4”
(6mm) NPT female inlets.
FEATURE BENEFITS
Flow tube is extra long and is accurate to within 3% of the full scale reading.
Tubes are made of shatter resistant Lexan™.
Flow tube has a unique ball guide which centers the ball in the tube
and keeps it centered. A ball floating in a non-centering tube allows the ball
to float off-center and will result in greater flows than the reading indicates.
Selec-O-Gas™ Flow Tube - Just rotate the outer tube to the scale you desire for:
• Argon • CO

• Helium • General/Any Gas
