Description
The Gentec FM197 is a back-pressure-compensated oxygen flowmeter calibrated for 0-15 LPM (litres per minute) flow range — covering standard medical oxygen administration from low-flow nasal cannula through high-flow mask therapy. Polycarbonate hood and tube provide durability and resistance to common cleaning agents and disinfectants, while the stainless-steel ball float ensures accurate flow indication.
Key Features
- Maximum-durability polycarbonate hood and tube — withstands regular use, impermeable to common cleaning agents and disinfectants.
- Back-pressure compensated — accurate flow indication regardless of supply pressure variations.
- Flow range 0-15 LPM — covers all standard oxygen therapy ranges.
- Calibrated at 50 psi and 70°F — clinical standard reference conditions.
- Stainless-steel ball float for accurate, durable flow indication.
- Slim body — fits in compact installations.
- CE-listed.

Where it's used
Hospital wards, GP and specialist clinics, ambulances, and aged-care facilities running medical oxygen delivery. The 0-15 LPM range covers everything from low-flow paediatric oxygen through high-flow adult therapy. Pair with a Gentec medical gas regulator (286 or 197M) for cylinder-fed setups, or connect directly to wall-pipeline oxygen at clinical facilities.
Frequently Asked Questions
Does back-pressure compensation matter?
Yes. Without it, downstream restrictions (humidifiers, narrow tubing) cause the flow indication to read incorrectly. Back-pressure compensation maintains accuracy regardless of downstream conditions — important for clinical accuracy.
FM197 vs FM187 — what's different?
FM197 is for medical oxygen; FM187 is for medical air. They're calibrated for different gas densities so they're not interchangeable.
What inlet fitting do I need?
Specify your supply type (cylinder DISS, AS-2473 quick-connect, or wall-pipeline) when ordering. Different inlets are available; the standard FM197 ships with the AU clinical-standard fitting.
