Yokogawa digital YEWFLO vortex flow meter combines the field proven sensor and body assembly used in more than 400,000 units installed worldwide

    General Introduction

    By the unique SSP (Spectral signal processing) technology, the digitalYEWFLO vortex flow meter is accurate and stable measurement of liquid, gas and steam, even in harsh process conditions. Combined with high reliability and robust design, it delivers improvements in plant efficiency and reduced operating costs. For digitalYEWFLO Multi-Variable Type (Option: /MV) built-in temperature sensor, so that temperature measurement and Mass Flow calculation is available. digitalYEWFLO Reduced Bore Type (Option: /R1, /R2) integrated and casting construction with concentric reduced bore piping.

    Besides, Yokogawa digital YEWFLO vortex flow meter come with several outstanding features as: SSP (Spectral signal processing) technology analyses the fluid conditions inside digital YEWFLO and uses the data to automatically select the optimum adjustment forthe application, advanced self-diagnostics function, High Accuracy as ±0.75% for liquid and ±1% for gas, Wide Process Temperature Range–196°C to +450°C and etc.
