high-quality oxygen and medical air flowmeters feature a durable, light-weight aluminum body, highstrength polycarbonate hood and metering tube, and stainless steel float. They are available as
single flowmeters, and in Y and T block configurations.
Solano Lumino is a medical device used for additional providing with oxygen to individuals with breathing-related disorders. Individuals whose oxygen concentration in their blood is lower than normal often require an oxygen concentrator to replace that oxygen.
Generally, you canâ??t buy an oxygen concentrator over the counter. A doctor must prescribe it after theyâ??ve completed a thorough medical evaluation. The oxygen concentrator output is measured in litres per minute. Your doctor will determine what level of oxygen you need, which may vary at rest, during sleep, and during physical activities.
How does it work?
Oxygen concentrator filters surrounding air, compressing it to the required density and then delivering purified medical-grade oxygen into a person.
Itâ??s also equipped with special filters which remove nitrogen from the air to ensure delivery of completely purified oxygen to the patient. This device also comes with an electronic user interface to adjust the levels of oxygen concentration and oxygen flow settings.
Oxygen is inhaled through the nasal cannula or special mask.
1. Recommended maximum oxygen flow: 5L/min.
2. Flow scope when the nominal pressure at the outlet is 7kPa: 0.5L/min5L/min.
3. Apply 7kPa back pressure at the recommended maximum flow, the flow reaches accuracy of ± 10% to the indicated flow.
4. Oxygen concentration when the nominal pressure at the output is zero (achieve the required oxygen concentration level within 30 minutes of the initial startup): the oxygen yield is 0.5L/min to 3L/min, the oxygen concentration is 90%.
5. Output pressure: 0.02MPa 0.07MPa
Application
The most common type of oxygen scavenger used in oil and gas production facilities is the sulfite ion, which is supplied as ammonium bisulfite, sodium sulfite, sodium bisulfite or sulfur dioxide. These sulfite scavengers react via a free-radical-chain mechanism, and thus are aided by the presence of a metal catalyst as an initiation step. Also, sodium hydrosulfate and hydrazine are used in limited applications
