Abstract
A fluid sampling system has a series of sample probes having inlets located at different positions across a fluid conveying duct. The outlets of all the sample probes are connected to a valve assembly. Each of the sample probes is made to have substantially the same length and diameter to provide equivalent transport times and volumes to fluids sampled from the various locations. The valve assembly allows selective connection of the sample probes to the fluid analyzer allowing either individual sample probes to be connected to the analyzer to determine local duct conditions or the connection of all the sample probes to the analyzer to determine the average duct condition.
