Product Description:

YJJ AFM07 Thermal Gas Mass Flowmeter Oxygen Compressed Air Replacement For SMC PFM7

Features:

AFMO7 series (standard model) gas mass flowmeter

High repeatability, TFT display

The AFM07 series is a gas mass flowmeter with outstanding performance and reliability, created based on the thermal measurement principle and combined with the MEMS mass flow chip independently developed by Aosong. This product measures the resistance change to calculate the mass flow of the measured gas, featuring precise measurement, stability, resistance to high and low temperatures, good linearity, fast response time, high integration of the whole machine, and high cost-effectiveness. It is equipped with a TFT display for reading, which can show instantaneous flow and cumulative flow. The display content can be rotated by 90 degrees to meet different installation angles of customers.

The AFM07 series products are small in size and come with a highly recognizable digital display, suitable for various scenarios where gas flow measurement is required. The AFM07 series has a strict factory calibration procedure and can directly output precise flow data, reducing the user's usage cost and the difficulty of secondary development.

The AFM07 series is suitable for measuring the mass flow of dry, clean and non-corrosive gases such as air, nitrogen, argon, carbon dioxide, and oxygen (excluding flammable and explosive gases). It has been widely applied in fields such as university research, fire protection, environmental monitoring, tobacco, smart agriculture, food, and medicine.
