Honeywell AWM5101VN AWM5103VC AWM5104VN Flow Meter Sensor
All three models belong to the AWM5000 series micro-bridge mass flow sensors, integrating built-in amplification, linearization and temperature compensation circuits with 1~5V linear analog output. They share identical electrical, mechanical and pressure resistance specifications, differing only in flow range, calibrated gas and temperature drift accuracy.
2. Common Electrical Specifications (Identical for All Three Models)
- Supply Voltage: DC 8V ~ 15V, typical supply 10V
- Output Signal: 1~5V DC linear voltage output (≈1V at zero flow, 5V at full scale)
- Linearity Error: Max. ±3% of reading within 2%~100% FS (Full Scale)
- Repeatability & Hysteresis: Max. ±0.5% of reading
- Response Time: ≤60 ms
- Power Consumption: Typical 50 mW
- Connector: 4-pin AMP 103956-3 compatible socket (factory equipped as standard)
3. Mechanical & Fluid Specifications (Identical for All Three Models)
- Fluid Port: 1/4″ NPT external thread (6.35 mm)
- Housing Material: Engineering plastic
- Maximum Common Pressure Endurance: 50 psi (3.45 bar)
- Max. Pressure Drop (At full scale): 2.25 inch H₂O (approx. 560 Pa)
- Leakage Rate: ≤0.1 psi/min under static pressure of 50 psi
- Shock Resistance: 100g peak, 6 ms half-sine wave shock, 3 times for each of 3 axes
- Applicable Media: Dry and clean gas (air, N₂, CO₂, argon, etc.); oil, moisture and dust-laden gas are prohibited
4. Ambient Temperature Specifications (Identical for All Three Models)
- Operating Temperature of Sensor: -20℃ ~ +70℃
- Measured Medium Temperature: 0℃ ~ +50℃
- Storage Temperature: -40℃ ~ +85℃
5. Suffix Code Definition (Key for Model Selection)
- VN: Factory-calibrated with nitrogen (N₂), temperature drift ±7%, high versatility, ideal for air and nitrogen measurement
- VC: Factory-calibrated for carbon dioxide (CO₂), dedicated to CO₂ measurement; temperature drift tolerance widened to ±10%. Fixed offset exists when measuring air/N₂, which requires software correction
- VA: Argon-calibrated (not included in these three models)
6. Quick Selection Guide
- Low flow nitrogen/air measurement → AWM5101VN (0~5 SLPM)
- Dedicated carbon dioxide gas measurement → AWM5103VC (0~15 SLPM)
- Medium-high flow nitrogen/air measurement → AWM5104VN (0~20 SLPM)
7. Typical Applications
Ventilators, gas analyzers, leak detection equipment, chromatographs, laboratory gas proportioning, industrial dry gas flow monitoring
