Gentec FM197BS-15L-SIS Oxygen Flowmeter

The Gentec FM197BS-15L is a Safety Instrumented System (SIS) oxygen flowmeter — the Australian-standard SIS-fitting variant of the FM197 family, calibrated for 0-15 LPM medical oxygen. Maximum-durability polycarbonate construction, long service life, and integrated safety valve make this the workhorse oxygen flowmeter for hospital ward and clinical-pipeline use.

Key Features

• SIS (Safety Instrumented System) oxygen-specific connection — Australian clinical standard.
• Maximum durability polycarbonate hood and tube.
• Long service life — designed for hospital ward continuous use.
• Integrated safety valve — protects downstream equipment and patients from over-pressure events.
• 0-15 LPM flow range — covers all standard oxygen therapy.

Specifications

• Gas service: Medical oxygen
• Flow range: 0-15 LPM
• Inlet: SIS (Safety Instrumented System) for oxygen
• Construction: Polycarbonate hood and tube
• Safety: Integrated safety valve

SIS — what it is and why it matters

The Sleeve Index System is the Australian-standard quick-connect for medical gas wall pipelines and equipment. Each gas has a unique sleeve geometry (oxygen ≠ medical air ≠ nitrous oxide) — preventing accidental cross-connection of incompatible gases. SIS is mandatory in most Australian clinical facilities; using the SIS-variant flowmeter ensures your equipment connects safely to standard wall-pipeline outlets.

Frequently Asked Questions

FM197BS vs FM197 — which?
FM197BS has the SIS quick-connect inlet. FM197 has a different inlet style (typically threaded). Specify SIS if your facility uses the standard Australian wall-pipeline system.

Standard or 90-degree variant?
Standard FM197BS for direct wall-mount alignment. 90-degree variant for installations where the flowmeter needs to angle outward from the wall (separate SKU).

Is the safety valve adjustable?
No — factory-set to clinical-standard relief pressure. Don't attempt to adjust it; that voids the safety certification.
