Product Details
MF4003-2-R-V-A Gas Mass Flow Sensor For Air Quality Analyzers
Emissions Monitoring
Product Features:
- High Sensitivity: Optimized for low-flow applications (0–2 SLPM)
with 100:1 turndown ratio .
- Fast Response: 10 ms default response time enables real-time
monitoring of dynamic processes .
- Dual Output: Standard 0.5–4.5 VDC analog signal with optional
RS485/RS232 for digital integration .
- Robust Design: IP65-rated housing and corrosion-resistant materials
ensure reliability in harsh environments .
- Customizable Options:
- Flow Range: Available in 2/5 SLPM for MF4003; 10–50 SLPM for MF4008
.
- Interface: BSPT 1/4" (R thread) or quick-connect fittings (4/6/8
mm) .
- Calibration: Supports gases like N₂, O₂, CO₂, and argon (contact
manufacturer for custom gases) .
- User-Friendly: 4-digit LED display shows instantaneous flow (SLPM)
and cumulative flow (SL), with push-button parameter configuration
.
Applications:
- Medical: Oxygen therapy systems, anesthesia machines, ventilators.
- Industrial: Process gas control, compressed air monitoring,
semiconductor manufacturing.
- Environmental: Air quality analyzers, emissions monitoring.
- Research: Laboratory gas chromatography, small-scale chemical
synthesis.
Installation & Operation Notes:
- Pipe Requirements: Install in straight pipe sections with ≥5×
diameter upstream/downstream clearance .
- Gas Compatibility: For gases other than air (e.g., CO₂, N₂O),
specify during ordering to ensure accurate calibration .
- Power Management: Ensure stable 8–24 VDC supply to minimize signal
noise.
- Calibration: Recalibrate every 12–24 months for optimal accuracy .
