FS1025

Datasheet FS1025 Liquid Flow Sensor Module The FS1025 liquid flow sensor module measures the Features flow rate using the thermo-transfer (calorimetric) Liquid flow: 0 to 7 liters/min principle. Robust solid isolation technology The FS1025 offers key advantages over resistor- Resistant to vibration and pressure shock based flow solutions. The sensor utilizes thermopile Minimal flow resistance sensing, which provides an excellent signal-to-noise Analog voltage output ratio. The sensor comprises a solid thermal isolation technology with protective coating. Supply voltage: 5V The non-linear flow output curve allows for sensitivity Applications from low to full-scale flow rates. The FS1025 provides analog output.
