For professional projects, you can write a C++ DLL that models the YF-S201 with non-linearities, hysteresis, and mechanical inertia. This requires the Proteus SDK (Software Development Kit), which is available to licensed users. This is beyond the scope of most hobbyists. If the download includes a

if (millis() - lastTime >= 1000) lastTime = millis(); // The YF-S201 gives 450 pulses per liter flowRate = (pulseCount / 450.0) * 60; // Calculate flow rate in liters per minute pulseCount = 0; // Reset pulse count = 1000) lastTime = millis()
