APPLICATIONS OF RADIOACTIVE LEVEL GAGES AND LEVEL INDICATORS

A remote-control level gage (UP-2) designed with an arc-shaped tubular bracket encircling the liquid container is described. One end of the bracket is equipped with a radiation source while the other end carries a gamma counter (AMM-7). The bracket can be placed below the liquid level, where the number of counts is (N/sub i/), then abcve the liquid level (N/sub i/), and then at the boundary between the media (N/sub 3/). The position of the bracket is indicated by an induction transmission. A level regulator, RUR-3, designed on the same principle, is used for measuring the liquid level in high-pressure apparatus. Safety and efficiency tests show favorable results; however, additional improvements are indicated. (R.V.J.)
