ABSTRACT:
Gas analyzing system using sonic wave shift over tubular gas column. Reference gas passed through column calibrates system to zero reference level. Sample gas having unknown amount of known gas component causes shift of wavelength distance in column. Phase comparator looks at shifted signal over .+-.90.degree. of phase shift. Integrator responds to comparator output to give dc output signal proportional to phase shift. Compensating circuits in final amplifier estimate probable final value based on rate of change of initial comparator output and use same to drive output meter.
