Pitot Static Tube
</dt>
A device consisting essentially of a unit combination of a pitot tube
and a static
tube arranged coaxially or otherwise parallel to one another, used
principally in measuring impact and static
pressures; also called pitot-static
head.
</dd>
The difference between impact and static pressure is used to measure
the velocity of flow past the tube by means of a differential-pressure gage.
The static pressure from a pitot-static tube may, in addition, be used in the
operation of an altimeter and similar instruments. [[/a>|/a>
