Product Description

The CMF5012 gas mass flow meter employs a micro-electromechanical system (MEMS) flow sensing chip, making it suitable for various applications involving clean and relatively dry gas flow measurement and process control. Its unique packaging technology accommodates different flow measurement ranges, ensuring high sensitivity, high reliability, high stability, and low cost.

The CMF5012 is based on a MEMS flow sensing unit integrated with a high-precision digital processing and calibration circuit (MCU). The integrated ∆-Σ A/D converter and internal calibration logic circuit, along with the MCU processor, ensure real-time, accurate flow signal acquisition and internal compensation, eliminating the need for external calibration. This guarantees high-precision flow output.

The digital communication output is user-friendly, allowing easy data retrieval through communication interfaces. The CMF5012's wide application range makes it a versatile solution for many industries.
