There is no universal method.

If you fill up with a little fuel, the readings do not change.

Sometimes even after filling up, they remain at the same level until you drive some distance.
The sensor is located inside a bubble, which is hidden from the outside by the tank itself. There is no access to it.

You can rock the car and the sensor will stop sticking.
