Seals fine on NPT threads with plenty of teflon tape, at least below 100 psi. If you're operating above that, don't buy Amazon grade sensors. It works down to 3.3v so you can hook it directly to a modern microcontroller such as the ESP32. Calibrate it yourself, though, if you want accuracy.

Perfect for my DIY water usage monitoring system. Accurate readings, durable build, and easy integration with my Arduino project. Threads were clean and fit standard fittings with no leaks. Will be ordering more

This flow sensor is very noisy and not accurate above 37l/ minute (10 Gallons/minute). It is 30% off, not really useful. I tried two, they were the same. The noise caused by the sensor impeller at medium to high flow is also very annoying because it is heard through the whole house as it is carried by the piping. Make sure you know what is the flow rate you are going to measure. If it is bellow 7 Gallons/minute you can give it a try. For higher flow rate look elsewhere.

The sensor came defective. Does not give output voltage.
