ABSTRACT:
A gas (including water vapor) monitor is provided which incorporates a dual chambered, constant volume peristaltic pump and flow meters. A sample gas is pumped at a constant volumetric flow rate into a processing zone where a predetermined component of the sample gas is separated. A make-up gas is then allowed to admix with the resulting gas and the mixture is then pumped at the same constant rate. The measured volume of the make-up gas thus required is equal to the actual volume of the separated component.
