The term oxygen flow meter refers to a device that measures and regulates the flow rate of oxygen gas delivered to a patient or process. In medical gas systems or industrial oxygen supply, accuracy, durability, safety and compatibility matter. Choosing a strong brand is important for reliability and maintenance. Below are ten brands that have distinguished themselves in flow-meter technology for oxygen or medical gas applications.
1. Precision Medical
Precision Medical is a U.S. manufacturer widely known for their chrome-body and compact flowmeters designed for oxygen and medical air. Their “Chrome Series” flowmeters are described as pressure‐compensated and built for consistent readings, with polycarbonate flow tubes and black glass indicator spheres. What stands out is durability—chemical‐resistant polycarbonate housings, reliable needle valves, and options for various quick‐connect fittings (.e.g., DISS, Ohmeda, Chemetron). If you need a clinical-grade oxygen flow meter for a hospital installation, Precision Medical is a strong choice.
2. Ohio Medical
Ohio Medical offers flow meters including the “7700 Flowmeter” series which are pressure‐compensated and designed for oxygen flow measurement. This brand is known for offering modular designs where the flow meter is integrated into the gas outlet assembly—reducing space usage and simplifying installations. For large healthcare facilities seeking standardization and reduced maintenance complexity, Ohio Medical is a reliable brand.
3. Dwyer/Sigma (or DwyerOmega)
While not exclusively dedicated to oxygen flow meters, DwyerOmega (a division of Dwyer) produces high-quality flow meters and sensors for gases and liquids. These instruments are more commonly seen in industrial or process applications rather than bedside clinical use. Nonetheless, for applications where an oxygen flow meter must operate outside the hospital environment (e.g., industrial oxygen supply, labs), DwyerOmega presents a credible option.
Their value lies in engineering robustness and adaptability to gas measurement tasks.
4. TSI Incorporated
TSI produces mass flow meters, and although many of their products are digital or geared to research/industrial use, they do list models for “air/oxygen gas mass flow meter” use. For users seeking high precision measurement of oxygen flow (instead of purely volumetric adjustments), TSI’s mass flow technology is compelling. While not a classic bedside “oxygen flow meter” for nasal cannula, it is worth considering for specialized applications.
5. E+E Elektronik
E+E Elektronik, an Austrian manufacturer, is included among brands offering oxygen or gas-flow measurement instrumentation through listings on industry directories. Their strength is in instrumentation for compressed gases, industrial measurement, and process control. If your requirement for an oxygen flow meter is in a non-medical, high‐end measurement scenario (e.g., oxygen manifolds, compressed gas delivery systems), E+E offers options with calibration and precision.
6. Brooks Instrument
Brooks Instrument is a historic name in flow measurement and control. They manufacture variable‐area (rotameter‐style) and thermal mass flow meters, among others. While Brooks is not typically marketed as a “bedside oxygen flow meter” brand, if you are selecting a flow meter for oxygen or other gases in laboratory or industrial settings, Brooks is a trusted brand.
They bring decades of experience in flow measurement and have a global presence.
7. Holykell
Holykell appears in listings of manufacturers of flow measurement devices for gases including oxygen. This brand may not have the same level of recognition in clinical oxygen flow meters as some of the dedicated medical-gas firms, but for industrial or OEM uses it offers viable solutions.
If your project involves oxygen flow measurement outside typical hospital settings, Holykell may be an economical selection.
8. Sensirion
Sensirion is a Swiss firm known for flow sensors including for oxygen and laboratory use. Their SFM30 series is cited for air/oxygen labs.
While their primary market is sensors and small‐scale instrumentation rather than large wall‐mounted flow meters, they are relevant for custom oxygen flow meter applications (for example gas bench measurement, calibration rigs or research equipment).
For advanced engineering or integration within a broader system, Sensirion offers modern sensor‐based solutions.
9. ENELSAN / ENELSAN Endüstriyel
ENELSAN Endüstriyel Elektronik Sanayi A.Ş. (Turkey) is one of the companies listed in the industry directory for oxygen flow meter products.
Although information is more limited, the presence of this brand underscores that there are diverse manufacturers globally. If you are sourcing for regional supply in EMEA or Asia-Pacific and need cost‐effective units, ENELSAN might be worth investigating.
The key here is to ensure regulatory compliance (e.g., medical gas standards) and quality control when using less widely recognized brands.
10. CS Instruments GmbH & Co. KG
CS Instruments GmbH & Co. KG is another brand cited in the industry directory for oxygen/gas flow measurement equipment.
Although more commonly known for process instrumentation, they include variable‐area flow meters for oxygen and other gases.
If your application is industrial or process-oriented (e.g., oxygen supply systems in manufacturing, HVAC, or medical gas manifolds) rather than patient delivery, CS Instruments is a credible option.
Conclusion
Selecting the right brand of oxygen flow meter depends on your specific application. If you are working in a hospital or clinical setting and you need a dependable bedside or wall-mounted unit, brands like Precision Medical or Ohio Medical are focused on medical‐gas delivery and have strong reputations. If your needs are more industrial, research or OEM-oriented, brands like Brooks Instrument, Sensirion, TSI, E+E, Holykell and CS Instruments broaden the options.
