Abstract
The gas analyser instantaneously tests the percentages of the components of a gas mixt. comprising carbon dioxide and oxygen, or a ternary one also contg. saturated steam. The analyser is esp. for the supply of fuel to a submarine engine. A gas temp. test device (1) is included and a velocity tester (2-6) tests the sound propagation velocity (V) in the gas mixt. The velocity tester comprises a phase comparator (4) whose output signal provides a measure of the acoustic velocity of the gas mixt. in which emitting and receiving electroacoustic transducers (3, 5) are kept a fixe distance apart. Comparison of the value calculated for V2/T with data stored in a memory (8) gives an indication of the weight percentage oxygen content.
