  • System for level gauging and providing alarms for a storage room using two gauging devices for determining a current level value
    Patent number: 6922150
    Abstract: Method and device for calculating the level of the surface of a product in a storage room by a radar level gauging system, which includes a first gauging device for calculating a first value of level and functionally separated from the first gauging device a second gauging device for calculating a second value of said level, wherein: a first signal is produced being dependent of a preset first threshold value of the level in the first gauging device, a first current level value signal is output from the first gauging device, a second signal is produced in dependence of a preset second threshold value of the level in the second gauging device, a second current level value signal is output from the second gauging device and the value of the current level of said surface is presented by an indicating unit adapted to receive at least one of the first level value signal and the second level value signal for evaluation of the current level value.
