| Description | Flow Switch | Mfr. Part # | AFM0750H00 |
| Model Number | AFM0750H00 |
The AFM07 Series Gas Mass Flow Meter, developed by Aosong, integrates mass flow and temperature measurement based on thermal measurement principles and Aosong's proprietary MEMS mass flow chip. It offers excellent performance, stability, and reliability. This device accurately measures gas mass flow by detecting resistance changes, providing advantages such as high precision, stability, wide temperature tolerance, good linearity, fast response times, high integration, and cost-effectiveness. It features an LCD screen for displaying instantaneous and cumulative flow, with a 90 rotatable display for flexible installation angles. The compact AFM07 series is suitable for various gas flow measurement scenarios, including air, nitrogen, argon, carbon dioxide, and oxygen (excluding flammable, explosive, corrosive, or wet gases). It is widely used in research, environmental monitoring, tobacco, smart agriculture, food, and pharmaceutical industries. The product undergoes rigorous factory calibration, enabling direct output of precise flow data, reducing user costs and development complexity.
