ABSTRACT:
An apparatus for sampling liquids flowing in open channels includes a cylinder into which liquid is drawn by the action of a large piston. When the piston is drawn to the top of the cylinder, liquid enters at the bottom of the cylinder by way of an inlet leading to a sample tube, the lower end of which is immersed in the channel. A small retaining tank is located at the base of the cylinder so that, when the piston is reversed and the liquid expelled from the cylinder, a small portion is retained in this tank. The tank leads to a sample valve which releases the contents of the tank into a collecting vessel at the end of each sampling cycle. A preferred embodiment of this invention has a vent valve to introduce pressurized air into the cylinder to purge liquid from the sampler. This apparatus is well suited for the application of pneumatic components to provide the control and the working power.
