Hot selling AFM07 series replaces SMC PFM7 thermal gas mass flowmeter with oxygen compressed air

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.

Product Features

• Gas mass flow meter

• Integrated mass flow and temperature measurement

• Good repeatability

• Supporting multiple gas measurements

• Standard Modbus RTU communication

• 2 NPN collector open circuit outputs (for upper and lower limit alarms)

• 1-5V linear voltage output

• LCD screen display

• 9-24V DC power supply

Product Applications

The AFM07 series is suitable for mass flow monitoring of dry, clean, and non corrosive gases (excluding flammable and explosive gases) such as 

air, nitrogen, argon, carbon dioxide, and oxygen. It has been widely used in industries such as scientific research in universities, fire protection, 

environmental monitoring, tobacco, smart agriculture, food, and medicine.
