FS1025-DG Gas Flow Sensor Module Datasheet The FS1025-DG Gas Flow Sensor Module measures the flow rate using the thermo-transfer (calorimetric) principle. The FS1025-DG offers key advantages over resistorbased flow solutions. The sensor uses thermopile sensing, which provides an excellent signal-to-noise ratio. The sensor comprises a “solid” thermal isolation technology with protective coating. The FS1025-DG provides calibrated linear output through digital I2C and analog interface. FS1025-DG .
