Gas analyser for the instantaneous measurement of the percentages of components of a ternary gas mixture consisting of carbon dioxide, oxygen and saturated water vapour, intended in particular for the fuelling of a power plant for underwater operation only

摘要

A gas analyzer for instantaneously testing the percentages of the components of a binary gas mixture comprising carbon dioxide and oxygen, or a ternary one also containing saturated steam, which is intended more particularly for the supply of fuel to an engine for submarine operation, said analyzer including a temperature test apparatus to test the temperature T of the gas mixture, a sound velocity test apparatus, comprising an ultrasonic generator receiver and phase comparator to test the sound transmission velocity V in the gas mixture and a calculator to calculate the value of the ratio V2/T or a value proportional thereto.
