O2 Flow Meters and Oxygen Flow Meters for Certified Clean Gas Infrastructure
Quick Answer
Silver Automation Instruments supplies O2 flow meters and oxygen flow meters for clean gas systems. We provide direct mass flow measurement, not inferred readings, for pipe sizes from DN6 to DN200. Send your oxygen pressure, temperature, line size, and required flow range to get a quote from our engineers.
Why Certification Matters for Oxygen Flow Meters
Oxygen service demands clean handling. A certified clean gas infrastructure instrument has been cleaned for oxygen use, with no oil or grease residues. Our O2 flow meters are cleaned and bagged according to industrial gas standards. We serve customers in Southeast Asia, the Middle East, and Latin America who install oxygen lines in hospitals, steel plants, and wastewater treatment plants. One customer in Vietnam ordered 12 thermal mass oxygen flow meters last year for a gas distribution skid. The pipe size was DN25 and the flow range was 0 to 50 Nm3/h. This level of detail matters because oxygen flow is often measured at low pressure.
Direct Mass Flow for Oxygen Lines
Most engineers skip the temperature and pressure compensation when possible. Thermal mass flow meters read direct mass flow for oxygen and clean gases. That means no separate temperature sensor or pressure transmitter is needed for a typical 4-20 mA HART loop. Our Silver Instruments O2 flow meter outputs 4-20 mA HART, RS485 Modbus, or pulse. Accuracy is 1.0 percent of reading plus 0.5 percent full scale from 0.5 to 50 Nm3/h. For larger oxygen headers, we offer inline flow meters from DN15 to DN200. We often see customers use these units for oxygen injection in aquaculture and ozone generation.
Common Oxygen Flow Applications
Oxygen flow meters from Silver Automation Instruments appear in clean gas panels, medical gas manifolds, and ozone systems. A water utility in Chile installed a DN40 O2 flow meter to monitor oxygen feed to an ozone contact basin. The meter measured 0 to 20 Nm3/h at 2 bar and 25 degrees C. A steel plant in the Middle East used the same meter type for oxygen lancing at 4 bar. In both cases the customer requested oxygen-clean certification and a calibration certificate traceable to ISO 17025. That request is the type we handle every week.
How to Specify an O2 Flow Meter
Sending a clear inquiry saves time. Tell us the oxygen pressure in bar, the temperature in degrees C, the pipe size in DN, and the minimum and maximum flow rate. If the gas is pure oxygen or mixed gas, state that too. Our engineers will select a thermal mass flow meter or a Coriolis mass flow meter based on the density and flow range. For low flow oxygen in laboratories, a thermal mass meter with 1/4 inch compression fittings works well. For high flow oxygen in industrial lines, an inline DN50 or DN80 meter is common. We provide a full data sheet before you order. We also supply oxygen flow totalizers and paperless recorders for audit-ready gas measurement.
Price and Lead Time
Price depends on pipe size, flow range, and certification level. A small DN15 thermal mass O2 flow meter for clean gas service starts around 850 USD. A DN50 oxygen flow meter with 4-20 mA HART and oxygen-clean certificate starts around 1,400 USD. Typical lead time is 7 to 12 working days. We ship from our Nanjing facility to Southeast Asia, Oceania, Latin America, Africa, and the Middle East by DHL, FedEx, or sea freight. Send us your required flow range and pipe size and we will return a quotation within 24 hours.
FAQ: O2 Flow Meters and Oxygen Flow Meters
Q: What is the difference between O2 flow meters and oxygen flow meters?
They refer to the same type of instrument. O2 is the chemical formula for oxygen. We use both terms for search clarity.
