Abstract
A pressure rise tube sampler for sampling liquid flowing in a conduit under high pressure including a pressure rise tube, a side arm sampler in communication with the rise tube, a first valve arrangement for permitting high pressure liquid to enter the rise tube from a high pressure liquid conduit, a liquid level control for closing the first valve arrangement after the liquid level in the rise tube has exceeded the level of the side arm and for opening a second valve arrangement to permit the liquid to be forced from the rise tube by the air which it compressed in entering the rise tube, and a third valve arrangement in the side arm for permitting liquid to be discharged therefrom into a container for analysis purposes.
