摘要： System and method for measuring the level of gas in liquid form in a composite pressure vessel that uses electrical capacitance to perform the measuring wherein the system comprises: a sensor unit suspended from an inlet-outlet unit and arranged to extend into the pressure vessel, wherein the sensor unit comprises a capacitive measuring unit for measuring the level of gas in liquid form in the pressure vessel, at least two sensor electrodes connected to the capacitive measuring unit, a communication unit for communicating the information measured by the capacitive measuring unit, and a power unit for supplying power to at least one of the at least two electrodes, the capacitive measuring unit and the communication unit.
