Sensirion Bi-Directional Flow Meter for Air 2.7V, -150L/min Min, 300L/min Max SFM3003

The Sensirion SFM3003 bi-directional flow meter is a precision device designed for accurate air, oxygen, and mixed gas flow measurement within the range of -150L/min to 300L/min. This flow meter operates at a maximum supply voltage of 2.7V and can withstand pressures up to 1.3 bar. It features a robust performance across a temperature range from -20°C to 85°C, making it suitable for diverse industrial and medical applications.

The SFM3003 series builds upon the proven SFM3000 form factor, enhancing the measurable flow range and adding key features, including a bi-directional flow option that enables measurement of negative and positive flow rates without the need for recalibration. Its low pressure drop characteristic ensures minimal impact on system performance and reduces power consumption.

This flow meter uses a digital I²C interface for straightforward integration with control systems, allowing precise flow monitoring and control. The sensor's calibration for air, oxygen, and their mixtures permits versatile use in medical devices such as ventilators and respiratory monitors, in addition to various industrial processes requiring reliable and repeatable flow measurement.
