Product selling points (self-built website)

1. TOF ultrasonic technology, **collecting both oxygen purity + flow rate parameters simultaneously**, single module replaces two sensors

2. New addition of **pressure compensation**, still stable in pressure fluctuation conditions, suitable for HFNC high-flow equipment

3. Flow upper limit increased to 20L/min, covering the demand of large-flow oxygen generators

4. No consumable materials, long service life, significantly reducing maintenance and calibration costs

5. UART digital serial output, convenient for integration into embedded motherboards, ODM development / maintenance replacement are possible
