Fluid transport system including a flow measurement system and a purge system

A flow measurement system comprising:

• a probe configured to contact a flowing fluid, said probe comprising:
• a first end defining a plurality of sensing ports for the fluid to flow into said probe;
• a second end opposite said first end;
• and
• a plurality of conduits extending between said first end and said second end, said plurality of conduits coupled to said plurality of sensing ports such that the fluid flows through said plurality of conduits;
• a plurality of tubes coupled to said plurality of conduits such that the fluid flows through said plurality of tubes;
• a differential pressure sensor in fluid communication with said plurality of tubes such that said differential pressure sensor determines a differential pressure of the fluid in the plurality of tubes;
• and
• a purge system in fluid communication with said plurality of tubes, said purge system including a source of purge liquid, said purge system configured to direct the purge liquid through said plurality of tubes.

A method of measuring a characteristic of a fluid flow, said method comprising:

• positioning a probe in the fluid flow such that fluid flow enters a plurality of conduits of the probe through a plurality of sensor ports;
• purging a plurality of tubes in fluid communication with the plurality of conduits with a purge liquid from a purge liquid source;
• and
• measuring a differential pressure between the fluid in the plurality of tubes using a differential pressure sensor in fluid communication with the plurality of tubes.
