Product Description

Advanced Self-diagnostics

Provides diagnostic messages on high vibration environments, excessive flow fluctuations, and clogging or plugging in the area around the shedder bar. Analysis of the process allows true condition-based maintenance.

Noise Reduction

Noise caused by strong piping vibration may affect the accuracy of the vortex frequency detection. The two piezoelectric elements installed in the digital YEWFLO are of a polarized structure, so they do not detect vibration in the flow or vertical directions. The noise in the lift direction vibration is reduced by adjusting the outputs of the piezoelectric elements.

Spectral Signal Processing (SSP)

In the past, some process conditions required manual adjustment to compensate for piping vibration noise. But, Yokogawa’s digitalYEWFLO Spectral Signal Processing (SSP) analyzes the detected frequency and allows only vortex frequencies to pass through the segmented band-pass-filter, thereby accurately identifying and eliminating noise. The SSP function only outputs the appropriate vortex frequencies, even under fluctuating flow rate conditions.
