| Abstract: | A functional relationship has been established through theoretical devivation for the pressure difference signal between the inner and outer rings of the primary wind pipeline elbow and the primary wind velocity. Experimental study proved that this functional relationship is perfectly right, and the magnitude of the elbow angle has no effect on it in any way. Actual applications showed this technique has very high reliability and accuracy; it can be used to eliminate the wear of primary parts; and for its lower cost and higher generality, it can be used to fully satisfy the need for on line monitoring of primary wind velocity. |
