Yokogawa DY Vortex Flow Meter digitalYEWFLO Vortex Flowmeter The new digitalYEWFLO vortex flowmeter will provide stable, accurate measurements at low flows even in noisy environments without any need for start-up tuning. The user benefits through greater reliability, reduced maintenance and a lower total cost of ownership. New functions with Spectral Signal Processing (SSP) technology SSP analyses the fluid conditions inside the digitalYEWFLO vortex flowmeter and uses the data to automatically select the optimum adjustment for the application, providing features never seen before in a vortex flowmeter. SSP accurately senses vortices in the low flow range, providing outstanding flow stability. Advanced self-diagnostics Application conditions such as high pipeline vibration and abnormal flow are predicted and indicated. High accuracy Wide process temperature range Simple parameter settings Clear, concise indicator Dual output for analog/pulse Alarm output BRAIN/HART communication and key switches for human-machine interface NACE compliant NAMUR 43 compliant Remote cable length up to 30mPackaging & Delivery

Yokogawa DY Vortex Flow Meter
1. Easy installation without calibration.
2. Stable without regular maintenance.
The new digitalYEWFLO vortex flowmeter is the latest offering in our line of world class vortex flowmeters. Based on the field-proven sensor technology of the YEWFLO series of vortex flowmeters, digitalYEWFLO offers a unique signal processing technique that extends the features of DSP.
The advanced processing algorithms are known as Spectral Signal Processing (SSP). SSP analyzes the vortex waveform into its spectral components to filter noise from signal for the most stable measurement possible.
With more than 300,000 vortex flowmeter installations, YEWFLO continues to prove itself in applications such as chemicals, natural gas and energy management.
Providing highly accurate and reliable flow measurement, YEWFLO vortex flowmeters are ideal for measuring clean, low viscosity fluids while saving you money on installation and cost of ownership.
The digitalYEWFLO vortex flowmeter combines the field proven sensor and body assembly used in more than 260,000 units worldwide with unique digital electronics including SSP technology.
