Factory Direct Yokogawa DigitalYEWFLO Vortex Flowmeter DY050 with SSP Technology
Product Description
The DY050 is part of Yokogawa’s digital YEWFLO vortex flowmeter series. The "DY" stands for the digital version, and "050" refers to the 50 mm (2") pipe size. It’s widely used to measure volumetric flow rates of liquids, gases, and steam using the vortex shedding principle.
Working Principle – Vortex Shedding
The DY050 operates based on the Kármán vortex street phenomenon:
