Abstract
Discloses a system for the analysis and measurement of selected gases such as combustible gases contained in a gaseous sample to be analyzed including a mixing manifold arrangement to mix the sample gas with a diluting gas to provide a constant gas output flow rate to a detector system. The mixing manifold arrangement automatically reconfigures itself to provide an optimal concentration ratio of sample and diluting mixed gas to the detector system. A constant sample gas input rate is preferred. Excess sample gas not required to maintain a constant mixed sample output rate is discharged.
Claims9
A method of measuring a gas mixture comprising:
- (i). receiving a sample gas from a source at a predetermined sample gas flow rate;
- (ii). supplying a gas mixture to a detector at a predetermined detector supply gas flow rate;
- (iii) receiving a detector signalling produced by a detector monitoring the gas mixture supplied by step (ii);
- (iv) periodically comparing the received detector signalling to a predetermined range;
- (v) mixing a supply of diluting gas with a portion of the sample gas flow to supply the gas mixture at the predetermined detector supply gas flow rate of step (ii) to maintain the received detector signalling within the predetermined range;
- whereby the sample gas received in step (i) is received at a predetermined sample gas flow rate and the gas mixture supplied to the detector is supplied at a predetermined detector supply gas flow rate.
