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.
