Fluid sampling device

A fluid sampling system for providing a fluid sample to a fluid processing apparatus, said sampling system comprising:

• a sample outlet to be connected to the input of the fluid processing apparatus;
• a plurality of sampling channels, each of said sampling channels comprising:
• an inlet line receiving a fluid and an outlet line conveying said fluid to said sample outlet;
• a valve connected to said inlet line and to said outlet line, said valve having a closed position preventing a fluid flow between said inlet line and said outlet line and an open position allowing a fluid flow between said inlet line and said outlet line;
• a first purge line connected to said inlet line for purging fluid therefrom, and a second purge line connected to said outlet line for purging fluid therefrom;
• and
• flow controlling means for controlling a fluid flow in each of said first and second purge lines;
• said fluid sampling system further comprising:
• a connecting line for connecting said outlet lines of said plurality of sampling channels to each other and to said sample outlet;
• and
• valve control means for selectively setting the valve of one of said sampling channels in the opened position to permit fluid to flow from said inlet line to said outlet line of said one sampling channel and the valves of the remaining sampling channels in the closed position.
