Until then, the methods described above (VCO + potentiometer) are the industry standard for simulating the YF-S201 in Proteus. To directly answer the question: There is no official YF-S201 Proteus library . You will not find a single file to download and drop into your LIBRARY folder. However, that should not stop your simulation work.
If you have searched for "YF-S201 Proteus Library" on Google, GitHub, or Labcenter’s official forums, you have likely come up empty-handed. Out of the box, Proteus (version 8 and 9) does not include a native simulation model for flow sensors. yf-s201 proteus library
