In order to develop the trace tritium monitoring technologies in exhaust gas of nuclear power plants and other apparatus, a high-temperature proton conductor ceramic CaZr0.9In0.1O3-α was used as hydrogen sensor for monitoring. The extraction characteristics an electrochemical isotopes using one-closed tube were studied case helium with 100 ppm 10ppm levels hydro...

Abstract We propose a new type of liquid hydrogen level sensor and evaluate prototype system with nitrogen. The acquires images the surface, which is illuminated by point sources light, estimates image processing. This scheme allows us to avoid immersion body into also eliminate necessity for any electrical wire connected body. accuracy estimated be ≈ 4.8 mm in our experiment using 10 liter nit...
