摘要: The present meter is characterized by its very accurate cosine response tourrent vector components of fluid (air or water) velocity parallel to the rotational axes propeller-like flow sensors. Structurally, it employs two sensors rotatably mounted on a rod `sting` carried casing. Each sensor includes pair back-to-back propellers fans single axial shaft supported rod. are normal one other and also axis Rotation activates switch-like arrangement electrically coupled an up-down counter in Blade rotation direction yields `up` count vice versa.
