Abstract
A fluid sampling device or system for providing a fluid to a fluid processing apparatus. The system includes a plurality of sampling lines, each having an inlet line and an outlet line connected by a valve. The valve has a closed position preventing a fluid flow between the two lines and an opened position allowing such a fluid flow. A first and a second purge line are provided, respectively connected to the inlet and outlet lines for purging fluid therefrom. Rotometers or other similar devices are provided for controlling each of the purge lines. A connecting line is provided for connecting each of the outlet lines to each other and to the outlet. In operation, one of the valves is opened and the others are closed. Fluid flows from the selected valve to the apparatus and backwards through the outlet lines of the unselected sampling channels, providing a backpurge of these outlet lines through the second purge lines.
