Hot selling AFM07025 Gas Thermal Mass Flowmeter Flow 25L/50L Replace SMC PFM7 Quality Assurance

Product Descriptions

The AFM07 series is a high-performance, stable and reliable gas mass flow meter based on the principle of thermal measurement, combined 

with the MEMS mass flow chip independently developed by Oson. This product calculates the mass flow rate of the measured gas by measuring 

resistance changes. It has the advantages of being intuitive, accurate, stable, resistant to high and low temperatures, good linearity, fast 

response time, high overall integration, and high cost-effectiveness. The AFM07 series products have a compact size and a highly recognizable 

digital display screen, suitable for various scenarios that require gas flow measurement.

The AFM07 series has a strict factory calibration program that can directly output accurate flow data, reducing user costs and the difficulty of 

secondary development.
