F. USING A MAGNEHELIC

When measuring such small air pressures, the U-tube is often not accurate enough. Such small differences in pressure are most often measured by an inclined tube manometer or a Magnehelic pressure gage as shown in Illustration #2.

ILLUS. #2

For convenience and accuracy, an instrument known as a Pitot tube is used with the gage. The Pitot tube, as shown in Illustration #3, consists of two tubes – one within the other. The inner tube measures the total pressure alone, while the outer tube measures the static pressure alone.
