Description

The gas mass flow sensor is made of micro electro mechanical system (MEMS)  flow sensor chip, which is suitable for clean, 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.

It is based on MEMS flow sensing unit and high-precision digital processing  and calibration circuit (MCU). The integrated Δ - Σ A / D converter, logic circuit with  internal calibration function and MCU processor ensure the real-time and effective  acquisition of sensing signal, obtain accurate flow signal, and process the corresponding  compensation algorithm internally, so there is no need for any external calibration  compensation,Can ensure high-precision flow output; friendly digital output  communication mode, users can easily get the corresponding data information; product  application range is very broad.

Performance Parameter

Linear Output

Flow = [(VOUT -1 V) / 4 V] × full scale flow

For example: S5025AV has a full-scale traffic of 1000slpm.

When the output voltage is read at 2.5V, the instantaneous flow rate is  [（2.5V-1V）/4V×1000slpm] =375 slpm
