Back-Pressure Compensated Oxygen Flow Meter (0–15 LPM with Humidifier)
Engineered for adult bedside oxygen therapy across general wards and intensive care units. Features a precision back-pressure compensated rotameter tube ensuring reading accuracy even when connected to humidifiers or nebulizers, paired with a solid chrome-plated brass body and unbreakable 250ml polycarbonate humidifier bottle.
Core Technical Construction Metrics
Back-Pressure Compensation
Designed with the needle control valve situated downstream of the indicator float. This ensures the gas inside the rotameter tube remains at 4.2 bar pipeline pressure, guaranteeing that the indicated float position reflects the true delivered flow rate without distortion from humidifiers or nebulizers.
- True delivered flow accuracy ±5%
- Stable indicator float with zero bobbing
- 10 bar burst pressure rated polycarbonate tube
Autoclavable Humidifier Bottle
Manufactured from virgin medical-grade polycarbonate capable of repeated steam autoclave sterilization at 121°C. Fitted with a 2 psi safety pop-off relief valve that emits an audible alarm if downstream nasal tubing becomes pinched or occluded.
- 250ml capacity with clear MIN/MAX water levels
- Sintered bronze micro-bubble diffuser tube
- Audible kink/occlusion warning relief valve
Surgical Brass Construction
The flow meter body is hot-forged from CW617N medical brass, precision CNC machined, and finished with mirror chrome plating. The high-precision stainless steel needle valve spindle prevents gas leakage and wear across hundreds of thousands of flow adjustments.
- Solid forged brass body with electrolytic chrome
- British Standard BS 5682 quick-connect probe
- Double O-ring seal preventing micro gas loss
