How are level transmitters calibrated?

It also depends on the selection of the level transmitter. Different types of transmitters have different calibration methods and values; for example, capacitive level transmitters are calibrated using a \"U\"-shaped tube under pressure, based on the range of the capacitive transmitter. Zero output: 4mA, full-scale output: 20mA. For devices such as double-flange level transmitters, they can be calibrated using simple methods: the medium is water, the range is 0–1.5 meters, and the double-flange pressure-transmitting capillaries are filled with silicone oil having a density of 0.95; calibration is carried out using a set of standard devices via the dry calibration method. For detailed information, it is best to consult a professional in instrumentation. We are all amateurs.
Thank you; your response was already very professional. I’m wondering what the relationship is between the liquid level and the density of silicone oil?
Personally, I think! The zero point should be set when the container is empty, and 100% should be set when it’s full
