MF4003-2-R-V-A Air Flow Sensor

Technical Features:

1. Sensing Technology:
   • MEMS Thermal-D® Technology: Direct mass flow measurement without temperature/pressure compensation, ensuring high accuracy in low-flow applications .
2. Design Advantages:
   • Nano-Coated Sensor Surface: Resistant to oil, water, and fouling, enhancing long-term reliability .
   • Wide Dynamic Range: 100:1 turndown ratio for precise measurement across varying flow rates .
3. Flexible Configuration:
   • User-Configurable Parameters: Flow units (slpm/sccm), response time, and output scaling via front-panel buttons or digital interface .
   • Multi-Gas Support: Factory-calibrated for air; supports custom gas calibration (e.g., N₂, O₂) .

Applications:

• Medical: Anesthesia machines, ventilators, and oxygen delivery systems .
• Industrial: Process control, gas mixing, and semiconductor manufacturing .
• Analytical Instruments: Gas chromatographs, environmental monitoring, and air samplers .

Mechanical Dimensions:

Model Breakdown:

• MF4003: Series code (3mm internal diameter, low-flow sensor).
• 2: Full-scale flow rate (2 slpm).
• R: Connection type (1/4" BSPT Threaded Port).
