3 Terms and definitions

The following terms and definitions as defined in GB/T 19677-2005 and GB/T 50095-2014 apply to this document. 3.1 Cup-type current-meters A rotary flow cup is used as a flow meter for the rotor. [GB/T 19677-2005, definition 3.4.11.2.1] Note. The rotating cup is evenly mounted on the circumference of the rotary disc to form a rotating cup part. When placed in the water stream, the cup component rotates. Usually install this turn with a vertical axis child. Therefore, it can also be called a vertical axis flow meter. 3.2 Propeller-typecurrent-meters A flow meter with a propeller as the rotor. [GB/T 19677-2005, definition 3.4.11.2.1] Note. Blades with several plane angles are evenly mounted on a wheel housing, or two or more helical blades surround the column. Rotary paddle. When placed in a stream of water, the propeller can rotate about a horizontal axis. Therefore, it can also be called a horizontal axis flow meter. ......
