The invention refers to a device for sensing and indication of a predetermined fluid level in a bottle, especially during refilling of a container for condensed gas under pressure. The purpose of the invention is to enable refilling to a predetermined level, which has earlier not been possible due to the heavy turbulence which arises as a result of boiling the condensed gas during refilling. According to the invention, this goal is achieved through the sensor device (7) being set up in the bottle at a level which corresponds to the predetermined level for the fluid, at which the sensor device (7) is connected with an external indicator device outside of the tank and is set up to emit a signal to this when the predetermined fluid level is reached, as well as that a protective casing (6,10) is arranged around the sensor device (7) in order to reduce the effects of the sensor device (7) resulting in wave motion in the fluid surface.<IMAGE> |
