FS1023 Liquid Flow Sensor Module Datasheet The FS1023 liquid flow sensor module measures the flow rate using the thermo-transfer (calorimetric) principle. The FS1023 offers key advantages over resistorbased flow solutions. The sensor utilizes thermopile sensing, which provides an excellent signal-to-noise ratio. The sensor comprises 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 FS10.

FS1023 Liquid Flow Sensor Module Datasheet The FS1023 liquid flow sensor module measures the flow rate using the thermo-transfer (calorimetric) principle. The FS1023 offers key advantages over resistorbased flow solutions. The sensor utilizes thermopile sensing, which provides an excellent signal-to-noise ratio. The sensor comprises 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 FS1023 provides analog output. Module Picture Features ■ Liquid flow: 0 to 3 liters/min (with water) ■ Robust “solid” isolation technology ■ Resistant to vibration and pressure shock ■ Minimal flow resistance ■ Analog voltage output ■ Supply voltage: 5V Applications ■ Water dispensers ■ Liquid metering or switch ■ Process controls and monitoring R36DS0004EU0101 Rev.1.01 Sep 1, 2022 Page 1 © 2021-2022 Renesas Electronics FS1023 Datasheet Contents 1.
