FS1025 Datasheet | Renesas

Liquid Flow Sensor Module The FS1025 liquid flow sensor module measures the flow rate using the thermo-transfer (calorimetric) principle. The FS1025 offers key advantages over resistorbased flow solutions. The sensor uses thermopile sensing, which provides an excellent signal-to-noise ratio. The sensor prises a “solid” thermal isolation technology with protective coating. The non-linear flow output curve allows for sensitivity from low to full-scale flow rates. The FS1025 provides analog output.
