Operating Principle

|
The pitot tube is another primary flow element used to produce a differential pressure
for flow detection. In its simplest form, it consists of a tube with an opening at the
end. The small hole in the end is positioned such that it faces the flowing fluid. The
velocity of the fluid at the opening of the tube decreases to zero. This provides for
the high pressure input to a differential pressure detector. A pressure tap provides the
low pressure input.
