The digital YEWFLO vortex flow meter combines the field proven sensor and body assembly used in more than 450,000 units installed worldwide with a unique and powerful combination of digital technology that includes spectral signal processing (SSP), a Yokogawa innovation. The digitalYEWFLO vortex flow meter is accurate and stable, even in harsh process conditions, and has a highly reliable and robust design that delivers improvements in plant efficiency and reduced operating costs
Sleep better knowing that your Yokogawa digitalYEWFLO vortex meters have the durability and reliability that you can count on.
Durability through simple design and construction.
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.
Combining Noise Reduction and Spectral Signal Processing (SSP) to provide an accurate and stable measurement.
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.
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.
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 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.
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.
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.

The FieldMate family effectively supports the initial setup, daily maintenance, and troubleshooting for the maximum utilization of intelligent field instruments. FieldMate is a flag ship product of the FieldMate family which is a PC based full functional and full field protocol configuration tool. The YHC5150X FieldMate Handheld Communicator is the latest HART Communicator from Yokogawa.
FieldMate 3.0 is a PC based tool that enables you to see intelligent field devices clearly, know their condition in advance, and act with agility throughout maintenance work flow.
Progress in digital signal processing and network technologies has enabled advanced functions which cannot be achieved by traditional field devices with 4-20 mA signal, to be implemented on field devices. Standardization of international fieldbus specifications, notably the FOUNDATION™ Fieldbus, has enabled users to build optimum field networks comprised of freely chosen field devices from various device vendors.
