Hi. I can definitely say that if installed and calibrated correctly the water level sensor will work very accurately. I recommend using a liquid level sensor with high resolution and accuracy and calibrating it regularly to ensure accurate readings. If you need to measure the water level in a tank, a submersible sensor may be more suitable than a non-immersible sensor. It is also important to know that the sensor is properly maintained and cleaned to prevent any deposits from affecting its accuracy. Overall, I have found water level sensors to be very useful in my devices and I would definitely recommend them to others.
