Asair AFM3000 Mass Flow Meter - Digital I2C Interface
The Asair AFM3000 is a high-precision digital mass flow meter designed for demanding medical and industrial gas flow measurement applications. It features a bidirectional flow range, a digital I2C interface compatible with 5V microcontrollers and industrial PLCs, and delivers fully calibrated, temperature-compensated readings with minimal pressure drop.
Features
- Bidirectional flow measurement from -200 to +200 SLM (Standard Liters per Minute).
- High accuracy of 1.5% of measured value (typical) with ±0.5% repeatability.
- Digital I2C interface for direct integration with microcontrollers and data acquisition systems.
- Ultra-low pressure drop design ideal for sensitive applications like medical ventilation.
- Fully calibrated and temperature compensated for stable, reliable performance.

The AFM3000 mass flow meter utilizes Aosong’s advanced thermal sensor technology, combining a MEMS thermal sensor chip with a high-performance 24-bit ADC and CMOS microprocessor. This integrated design enables precise measurement of air, oxygen, and other non-corrosive gases with exceptionally fast signal processing and bidirectional capability.
Engineered specifically for low-pressure-drop applications, its optimized flow channel geometry minimizes resistance, making it extremely suitable for medical ventilator systems, respiratory devices, and process automation where maintaining system pressure is critical. The sensor operates from a 4.75 to 5.5 VDC supply, providing linearized and compensated digital output via I2C communication.
