A sampler for obtaining an isokinetic sample of a flowing fluid. A liquid-filled, fluid-tight container has a deflated bag within it. The sampler is positioned within the flowing fluid stream, and the liquid is pumped from the container at a rate proportional to the flow rate of the flowing fluid to draw a sample of the fluid into the bag at the same rate as the flow rate of the flowing fluid. When the bag is filled it can be removed from the container and the container inlet tube replaced, allowing the sampler to be used for another sample without laborious cleaning in the field.

[ What is claimed is:] [1.] A method of isokinetically obtaining a sample of a flowing fluid utilizing a liquid-filled fluid-tight container having therein a deflated inflatable bag, the bag being in fluid communication with the exterior of the container, said method comprising the steps of:positioning the fluid-tight container at a location within a flowing fluid stream from which a sample is to be taken; andwithdrawing liquid from the container at a flow rate proportional to the flow rate of the flowing fluid stream to cause a sample of the fluid from the fluid stream to be drawn into the inflatable bag at a rate equal to the flow rate of the flowing fluid stream to inflate the bag within the container so as to replace the liquid withdrawn from the container.
