YOKOGAWA DIGITALYEWFLO DY050-EBMBA4-2N FF1 VORTEX FLOWMETER

Description:

The Yokogawa DY050-EBMBA4-2N FF1 digitalYEWFLO Vortex Flowmeter is a vortex shedding flow sensor used in industrial process systems for accurate measurement of liquid, gas, and steam flow rates. Commonly installed in steam lines, boiler systems, chemical processing plants, and power generation facilities for reliable and stable flow monitoring under varying process conditions. Maintenance teams and system integrators use this part for process measurement, system optimization, replacement of legacy flow meters, and ensuring accurate flow control in critical operations.

Applications:

The Yokogawa digitalYEWFLO DY050 is used in industrial environments to measure flow of liquids, gases, and steam using vortex shedding technology. It is widely applied in power plants, refineries, chemical facilities, and HVAC systems where consistent and accurate flow measurement is required for energy efficiency and process control. The digitalYEWFLO series incorporates Spectral Signal Processing (SSP) technology to maintain stable and accurate readings even under vibration, pulsation, and fluctuating flow conditions, improving plant efficiency and reducing operating costs.
