The present disclosure relates to a pressure vessel equipped with a permeated gas discharging structure, the pressure vessel including a nozzle boss into and from which a gas flows and is discharged; a liner coupled to a flange portion of the nozzle boss and provided with a space formed therein for receiving fluid; a discharge path forming part configured to form a gas discharging path from the nozzle boss side along an outer surface of the liner in a central axial direction; and a composite material provided at outer sides of the liner and the discharge path forming part.

A tank-in-tank fill level indicator, making use of noninvasive tank-in-tank measuring techniques. A vibration device, such as an exciter or resonator, vibrates the outer tank at its natural frequency of vibration, thereby inducing the vibration of the inner tank and a beating effect as a result of the interaction of the vibrations of the two tanks. A vibration detection device, such as an accelerometer, detects the resultant beating effect of the two tanks' induced vibrations. A data processing device, such as a microcontroller, processes the detection data to obtain the liquid volume. A display, wired or wireless data transmission device, or combination thereof, is then used to provide tank or container fill-level information.
