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:

• When fluid flows past a bluff body (called a "shedder bar") inside the pipe, vortices are alternately shed from its sides.
• The frequency of vortex shedding is directly proportional to the flow velocity.
• A piezoelectric sensor or capacitive sensor detects these vortices and converts the signal into a frequency, which is then interpreted as flow rate.

Technical Specifications

Optional Features (/MV, /HT, etc.)

Advanced Features

1. Spectral Signal Processing (SSP)
   • Reduces noise, increases stability, and improves signal detection.
   • Ideal for low flow rates and varying conditions.
2. Self-Diagnostics
   • Detects abnormal vibration, flow instability, or sensor degradation.
   • Can be integrated with asset management systems (e.g., Yokogawa’s PRM).
3. Mass Flow (with /MV)
   • Calculates mass flow of saturated steam or liquids using built-in temperature measurement.
