Overall Material Stainless Steel Aluminum Alloy Customizable Flow Meters
Product Description: CMF5012 Gas Mass Flow Meter
The CMF5012 gas mass flow meter utilizes a MEMS flow sensor chip, designed for clean and relatively dry gas flow measurement and process control across various applications. Featuring unique packaging technology, the CMF5012 ensures high sensitivity, reliability, stability, and cost-effectiveness across different flow ranges.
This meter integrates a MEMS flow sensing unit with a high-precision digital processing and calibration circuit (MCU). The internal Δ-Σ A/D converter, logic circuit, and MCU processor work together to collect sensing signals in real-time, producing accurate flow measurements with internal compensation algorithms, eliminating the need for external calibration.
Product Features:
- High Accuracy: Provides 1.5% Full Scale (FS) accuracy for precise measurements.
- Linear Output without Temperature Compensation: Delivers linear output without the need for temperature compensation.
- Long-Term Stability: Maintains minimal zero drift for consistent performance over time.
- Rapid Response Time: Features a quick 65 ms response time.
- Wide Velocity Range: Measures flow velocity from 0 to 60 m/s and withstands impacts up to 100 g.
- Robust Solid-State Sensing Core: No surface voids or fragile films, resistant to blockages and pressure shocks.
- Versatile Output Options: Provides analog output (1-5 V) and digital RS485 communication.
- Humidity Adaptability: Capable of measuring gases in high humidity environments.
- Temperature Resilience: Operates in temperatures from -25°C to 85°C, with storage temperatures ranging from -40°C to 90°C.
- Condensate Resistance: Sensor is designed to resist water condensation.
