Liquid Flow Sensor Module
FS1023
Datasheet
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 comprises a “solid”
thermal isolation technology and silicon-carbide coating, which
protects it from abrasive wear and provides robustness and long-
term reliability. In comparison, 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 component.
