ABSTRACT:
A bucket wheel assembly for use in a flow measuring device is disclosed wh comprises a one-piece, lightweight molded plastic disk having a plurality of roughly conical cups connected to a central ring. The central ring is mounted on a shaft and the disk rotates in response to fluid pressure in order to generate a signal proportional to flow velocity. The bucket wheel is advantageous over prior art versions in that it is responsive only to the horizontal component of flow velocity, when rigidly held, and thus gives truer and more accurate information with regard to current flow, particularly when used in current meters measuring flowing streams and rivers.
