Product Description

The CAFS5019 gas mass flow meter uses a micro-electromechanical system (MEMS) flow sensing chip, designed for clean and relatively dry gas flow measurement and process control across various applications. Its unique packaging technology accommodates different flow measurement ranges, ensuring high sensitivity, reliability, stability, and low cost.

The CAFS5019 consists of a MEMS flow sensing unit and a high-precision digital processing and calibration circuit (MCU). An integrated Δ-Σ A/D converter, internal calibration logic circuit, and MCU processor ensure real-time, accurate flow signal acquisition and internal compensation, eliminating the need for external calibration. This guarantees high-precision flow output.

With a user-friendly digital communication output, users can easily retrieve corresponding data. The wide application range of the CAFS5019 makes it a versatile solution for many industries.
