1. method that is used for determining the storage tank liquid level, this method comprises:

  • Storage tank is provided, and liquid level is variable in this storage tank;

    When the probe that is associated with described storage tank not when liquid phase in the described storage tank contacts, measure the baseline characteristic of the probe circuit that comprises described probe;

    After having measured described baseline characteristic, measure first feature of described probe circuit;

    AndDetermine corresponding to the described liquid level in the described storage tank of the moment of described first feature of about measurement based on described baseline characteristic.
