PRODUCT DESCRIPTION

Description

SF5025 gas mass flow meter is made of MEMS flow sensor chip, which is applicable to clean and relatively dry gas flow measurement and process control for various purposes. The unique packaging technology makes the product meet different range of flow measurement, ensuring high sensitivity, high reliability, high stability and low cost.

SF5025 is based on MEMS flow sensing unit and high-precision digital processing and calibration circuit (MCU) Δ-Σ A/D converter, logic circuit with internal calibration function and MCU processor jointly ensure that the sensing signal is effectively collected in real time, accurate flow signal is obtained, and the corresponding compensation algorithm is processed internally. Therefore, no external calibration compensation is required to ensure high-precision flow output;

Friendly digital output communication mode, users can easily get the corresponding data information through communication;

The product has a wide range of applications.
