| Description | Flow Switch RoHS | Mfr. Part # | AFM3020 |
| Model Number | AFM3020 |
The Aosong AFM3020 is a high-precision gas flow sensor designed for demanding applications, particularly in medical ventilation and respiratory systems. It accurately measures the flow of air, oxygen, and other non-corrosive gases with low pressure loss, ensuring optimal performance in critical environments. The sensor operates on a 5V supply voltage and features a digital I2C interface, providing calibrated and temperature-compensated measurements. Its advanced technology, based on a thermal sensing chip and a 24-bit CMOS microprocessor, ensures fast signal processing and superior accuracy compared to similar products. The AFM3020 is suitable for a wide range of applications including medical, process automation, burner control, fuel cell control, spectroscopy, environmental monitoring, and laboratories.
