Description
Oxygen flowmeters act as a vital component of oxygen supply systems in medical centers, and are requisite medical equipment for oxygen inhalation of first aid as well as hypoxic patients in the hospital.

The oxygen flowmeter can directly plug into the wall outlet and then connect with the oxygen source. By connecting the oxygen output to the nasal oxygen cannula, patients can inhale the oxygen that has been filtered and humidified for comfort.

The HS-XRQ-I oxygen flowmeter that pairs with minor-caliber humidifier bottles. Considering that some patients oxygen demand is low, it is recommended to use this oxygen device. Furthermore, the bottle is made through a low cost blow molding process, so it will reduce the procurement cost for medical institutions and make it suitable for purchasing in mass quantity.

• Working pressure: 0.2Mpa – 0.3Mpa
• Flow range: 1 – 10L/min
• Accuracy level: 4 (the level of air flow error)
• Gas medium: oxygen
• Humidifying water: distilled water or pure water
• Safety valve can vent automatically within the pressure range of 0.3Mpa ± 0.05Mpa.
• Oxygen output diameter size: the maximum size is Φ9mm, the minimum size is Φ5mm

• 
  Rotameter:
  the float sticks to the inner wall of the rotameter, and oxygen supply can be set according to patient need. The design of tube adopts a thickened explosion - proof way to avoid accidental injuries.
• Flow control valve:
  the valve, made of H59-1 brass with relatively high strength, can make the flowmeter last longer.
• Valve stem of flow control valve:
  made of 304 stainless steel with good corrosion resistance. So, valve stem will not rust in the process of humidifying oxygen and will not affect patient health.
• Oxygen input pipe:
  the pipe, made of PC material, can be sterilized at high temperature and reused. Moreover, a filter is assembled in the pipe to prevent impurities from entering the body.
• Humidifier bottle:
  made of PC material, not only can be sterilized at high temperature and reused but also eliminate cross infections. During application, pure water or cold water is put into the bottle, and then dry oxygen is humidified via passing through oxygen input pipe into the bottle, which can make the patients feel more comfortable during oxygen inhaling.
• Oxygen input plug:
  different sizes or shapes can be customized according to the standards of different countries.
• Flow control knob:
  oxygen flow rate can be adjusted according to patient needs.
• Silica gel is used to make the sealing element of oxygen flowmeter and characterized by corrosion, high temperature and low temperature resistance as well as good sealing performance.
