| description | To improve liquid level gauging inside liquid tanks, especially cryogenic liquid tanks, an apparatus and method for determining the liquid level are provided. A light source emits outgoing light rays that are back reflected or scattered by the tank wall of the liquid tank. The back reflected or scattered incoming light rays are received by a light conducting device, which conducts the incoming light rays towards a sensor device. The sensor device has optical sensors coupled to the light conducting device such that there is a one-two-one relationship between each optical sensor and a specific tank wall portion. Due to the change in the amount of light that is received by the optical sensor after the outgoing light rays were refracted by the liquid surface, the liquid level determining device is capable of determining the liquid level. |
