Liquid Flow Sensor Module Description The FS1025 MEMS Liquid Flow Sensor Module measures the flow rate using the thermo-transfer (calorimetric) principle. The FS1025 is designed to measure liquids. The FS1025 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 FS1025 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 FS1025 plies with the NSF/ANSI 61: Drinking Water System ponents - Health Effects standard.
