| Abstract: | The recent development of the sediment concentration gauge consisting of a 288Pu low-energy X-ray source, a proportional counter and a microcomputer is reported. The measuring method and its software, as well as the error analyses, are given. The minimum measurable sediment concentration is as low as 0.072 kg/m3, and the standard error is 0.024 kg/ m3. The effective measuring range of the probe is less than 5 cm, so the gauge is suitable lor measuring the concentration of the sediment near the bottom of a river. |
