摘要 |
The invention concerns a method for monitoring the inclination of a floating roof with respect to the free liquid surface in a liquid tank, in particular a fuel tank, whereby measurements of the height of the liquid surface with respect to the floating roof are performed at a plurality of spaced areas in the floating roof, following which the measurement values are transmitted to a monitoring unit which relates the measurement values from the individual areas to each other and generates a signal in response to this to indicate the inclination of the floating roof. This enables constant monitoring of the inclination of the floating roof in a simple manner, so that damaging effects because of e.g. wedging of the floating roof can be avoided. |
