Airgas® Model FM244A580 Brass High Purity Single Stage Flowmeter Regulator With CGA Connection
Specs:
This Airgas® FM244 series of high-purity, single-stage flowmeter regulators are recommended for non-corrosive analytical and process applications. This regulator is part of our analytical series, machined from brass bar stock which affords minimum internal volume and eliminates large cavities and pockets associated with forged-body regulators. The flowmeter has a 65mm direct reading scale (based on air) etched into the tube. Accuracy is +5% full scale with +.25% repeatability. You must specify flow rate and gas service at time of ordering.
Features
Filtered Seat: For added gas stream purity and extended service life.
Convoluted Stainless Steel Diaphragms: Eliminates outgassing associated with elastomeric diaphragms.
Bar Stock Body: Affords low internal volume.
Encapsulated Filter Seat Assembly: Protects valve seat, extends service life.
Nickel-Plated Brass Body: Provides enhanced overall aesthetics, will not tarnish.
Superior Leak Integrity: Provides superior leak integrity without contamination from non-metallic liner or seal.
Direct Reading Scale: Allows the operator to read the flow directly on the tube.
Safety Relief Valve: Protects flowmeter and any equipment down stream.
