Combining Noise Reduction and Spectral Signal Processing (SSP) to provide an accurate and stable measurement.


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.

Yokogawa's digitalYEWFLO is simple to integrate into your existing system.


Industry Standard Communication Protocols

Yokogawa digitalYEWFLO has the standard communication protocols used. Featuring BRAIN protocol, HART 5 protocol, HART 7 protocol, or FOUNDATION Fieldbus, the digitalYEWFLO can integrate quickly into your existing system.

Beyond Standard - Yokogawa's answers to your process needs.



Standard digitalYEWFLO

Standard digitalYEWFLO vortex flow meters are available in a number of different sizes ranging from 1/2-inch to 16-inch. Available with wafer style or flanged style (ANSI Class 150 to ANSI Class 900). digitalYEWFLO has the size you need.


Reduced Bore

The Reduced Bore digitalYEWFLO meter was designed to capture the low flow applications without the need to install concentric reducers. It is very common in vortex meter applications to use a smaller meter compared to the line size. This requires the installation of concentric reducers along with the correct amount of upstream and downstream meter run to ensure a proper flow profile into the meter. By utilizing built-in concentric reducers, we can reduce the meter ID by either one or two meter sizes. This feature allows you to install a line size meter, reduce installation cost, and measure your low flows. 

Reduced Bore




Remote electronics allows you to locate the indicator away from the process measurement point and to more convent visible area. Remote digitalYEWFLO vortex flow meters are available in a number of different sizes ranging from 1/2-inch to 16-inch. Available with wafer style or flanged style (ANSI Class 150 to ANSI Class 900). digitalYEWFLO has the size you need.
