Description
The Comweld Ezi-Flow Oxygen Flowmeter is the oxygen-gas variant of the Ezi-Flow line — pressure-compensated to deliver accurate prescribed flow regardless of supply pressure variations, suitable for most types of respiratory therapy. S.I.S. (Specific Index System) oxygen handwheel ensures safe, gas-specific connection. ±5% accuracy across the full 0-15 L/min range.
Key Features
- Pressure-compensated design — flow accuracy maintained regardless of supply pressure variations.
- 0-15 L/min outlet pressure range — standard respiratory therapy.
- ±5% accuracy (of full scale reading).
- S.I.S. oxygen handwheel for safe gas-specific connection.
- For oxygen gas service only.

Comweld vs Gentec flowmeters
Comweld and Gentec are both well-regarded medical flowmeter brands in Australia. Comweld has stronger heritage in Australian clinical supply chains; Gentec is the international standard with broader product range. Either is a good clinical-grade choice — pick by what your facility's purchasing or compliance practices favour. Comweld's Ezi-Flow line has the advantage of a slim profile and simple installation.
Frequently Asked Questions
Ezi-Flow Oxygen vs Ezi-Flow Air?
Same physical chassis, different gas calibration. Always match the flowmeter to the actual gas — substituting an air flowmeter on oxygen (or vice versa) will give inaccurate flow readings.
Can I use this on a cylinder regulator?
Yes — connect via a regulator with the matching SIS oxygen outlet. The flowmeter expects standard 400 kPa supply pressure.
Is back-pressure compensation the same as pressure-compensation?
Closely related concepts. Both ensure flow accuracy regardless of supply or downstream pressure variations. Comweld documents this as "pressure compensated"; Gentec uses "back-pressure compensated". Functionally equivalent for clinical use.
