AFM0750H00 0-50L/min MEMS Gas Flow Sensor (Replacement for SMC PFM7) for Air/Nitrogen/Oxygen

AFM0750H00 0-50L/min MEMS Gas Flow Sensor (Replacement for SMC PFM7) for Air/Nitrogen/Oxygen

Description:
The AFM07 Series is a high-performance, stable, and reliable gas mass flow meter based on the thermal measurement principle, combined with our independently developed MEMS mass flow sensor chip. This product calculates the mass flow rate of the measured gas by detecting resistance changes. It offers high measurement accuracy, stability, resistance to both high and low temperatures, excellent linearity, fast response time, high system integration, and an outstanding price-performance ratio.

The device features a built-in TFT display for real-time reading, capable of showing both instantaneous flow and totalized flow. The display content can be rotated 90° to accommodate different installation angles.

The AFM07 series has a compact form factor and a high-resolution digital display, making it suitable for a wide range of applications where gas flow measurement is required. Each unit undergoes a strict factory calibration process and can output precise flow data directly, reducing user operating costs and minimizing the difficulty of secondary development.
