Liquid Flow Sensor Module Description The FS1023 MEMS Liquid Flow Sensor Module measures the flow rate using the thermo-transfer (calorimetric) principle. The FS1023 is designed to measure liquids. The sensor output is amplified and trimmed at zero flow for module to module consistency. The FS1023 offers key advantages over resistor-based flow solutions. The sensor utilizes thermopile sensing, which provides an excellent signal-to-noise ratio. The sensor prises a “solid” thermal isolation technology and silicon-carbide coating, which protects it from abrasive wear and provides robustness and longterm reliability. In parison, other sensors typically contain a fragile membrane above an etched cavity for the thermal isolation base. There are no moving mechanical parts that can break in contrast to other flow meter types, such as a turbine-type meter. The FS1023 has minimal flow resistance, making it highly suitable for gravity-feed applications or for replacing a high-power pump with a lower power device. The FS1023 is a NSF-certified ponent.
