Description
SPECIFICATIONS:
The Oxygen Flow Meter Double-Tube is a premium, high-efficiency dual-line medical gas regulation device engineered to deliver accurate, independent oxygen therapy to two patients simultaneously from a single gas supply source. Utilizing back-pressure compensated double-tube architecture, it ensures uncompromised flow stability across both lines, regardless of line pressure variations. Constructed with a robust stainless steel or chrome-plated brass body and two shatterproof, crack-resistant polycarbonate flow chambers, it is optimized for high-volume clinical, operating theatre, and emergency environments.
Key Features
- Dual Independent Control: Equipped with two separate vertical Thorpe-tubes and independent micro-fine front control knobs, allowing clinicians to set distinct, precise flow rates for two patients from one outlet connection.
- Precision Back-Pressure Compensation: Specially engineered to isolate each tube from back-pressure changes, guaranteeing uncompromised volumetric dosing and steady flow rates.
- Shatterproof Visual Scales: Features dual, easy-to-read graduated scales housed within chemical-resistant polycarbonate inner and outer tubes for flawless, highly visible monitoring.
- Rugged Heavy-Duty Housing: Built with a solid, impact-resistant metallic core that withstands heavy daily usage, frequent clinical adjustments, and aggressive chemical disinfection routines.
- Universal Pipeline Compatibility: Designed to seamlessly couple with standard quick-connect wall probes or cylinders, eliminating the need for bulky manifold splitters.
Technical Specifications
- Model Configuration: FM4546-D (Double-Tube / D-Tube Dual Flowmeter).
- Flow Delivery Range: Dual independent lines calibrated for standard 0 to 15 Liters per Minute (L/min) medical oxygen delivery.
- Material Composition: Chrome-plated solid brass or stainless steel main body alloy [Image 1, Image 3] with high-impact, crystal-clear polycarbonate flow tube assemblies.
- Inlet Pressure Calibration: Preset and calibrated for standard 50 psi (3.5 to 4.0 Bar) centralized medical gas pipeline networks.
- Connection Adapter Options: Configurable with standard British Standard (BS), Ohmeda, Chemetron, DISS, or German DIN quick-connect safety probes.
- Primary Clinical Settings: Hospital Emergency Rooms, Intensive Care Units (ICU), Operating Theatres, Post-Anesthesia Recovery Units, and Multi-Bed General Wards
