Yokogawa’s digitalYEWFLO Classic Vortex Flow Meter includes spectral signal processing (SSP) to provide enhanced vibration immunity and optimum, stable flow measurements. Even under fluctuating flow rate conditions, SSP outputs only the appropriate vortex frequencies with no manual adjustments needed.
Our classic type vortex flow meter features:
- High accuracy:
- +/- 0.75% of reading (liquid)
- +/- 1% of reading (gas and steam)
- Remote electronics housing
- Advanced self-diagnostics
- Replaceable shedder bar
- High safety
- Reduced maintenance and TCO
Our Classic 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 and style you need for your process.
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.
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.
Details
Advanced Self-diagnostics
The digitalYEWFLO series vortex flow meter 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.
Replaceable Shedder Bar
If obstructions are present, Yokogawa’s unique design of the shedder bar allows the operator to replace it without removing the meter, minimizing downtime.
Remote Electronics Housing
Remote electronics allows you to locate the indicator away from the process measurement point and to a more convenient visible area.
The picture to the left shows a Stainless Steel housing. The SS housing is an available option on all Yokogawa digitalYEWFLO Vortex Flow Meters.
Reduced Maintenance and Total Cost of Ownership
Vortex Flowmeter calibration and advanced pre-delivery programming are included, so customers can easily integrate the vortex flow meter into their system with minimal downtime.
How our vortex flow meters reduce costs:
- Enhanced vibration immunity eliminates adjustment costs.
- Self-diagnostic functions reduce regular maintenance costs for a maintenance-free meter.
- User-friendly parameters are easily set by categorizing frequently used parameters into one group, reducing total maintenance costs.
Noise Reduction
Noise caused by strong piping vibration may affect the accuracy of vortex frequency detection. The two piezoelectric elements in the digitalYEWFLO are installed in a configuration that is polarized, so they are not affected by vibration in the flow or vertical directions. The noise of vortex (lift)-direction vibration is reduced by adjusting the outputs of the piezoelectric elements. Combining these features with the Spectral Signal Processing (SSP) function provides optimum and stable measurement.
Steam Flow Measurement
Steam has often been described as the 'lifeblood' of the industry. Vortex meters are known to be superior devices for steam flow measurement due to their inherent linear measurement, large turndown, low pressure drop, and high accuracy.
The vortex flow meter is ideal for high temperature, superheated, and saturated steam applications since it eliminates the need for separate components and associated installation temperature. In addition, it provides quality, dependability and high pressure ratings along with a stable and reliable flow measurement.

Liquid Applications
Liquid applications in the oil refinery industry become challenging since the process liquid is a higher viscosity at lower process temperatures. As a result, clogging becomes an issue when a flow meter has moving parts.
digitalYEWFLO vortex meters have advanced self-diagnostics that alert the operator if clogging or plugging in the area around the shedder bar are present. Alerts are also triggered in high-vibration environments and those with excessive flow fluctuations in the area around the shedder bar. This enables automatic condition-based maintenance.
Reverse Osmosis
RO systems are designed for automatic operation and require routine preventative and corrective maintenance. Common problems include membrane fouling and the use of improper flow rates.
Vortex flow meters measure low-conductivity flow, are cost-efficient, and deliver accurate flow rates, making them perfect for reverse osmosis applications.

Yokogawa Vortex Flow Meter Installation Manual
1, Wafer Type
Vertical Installation- (1) Insert two collars on each two bolts of bottom side of the flowmeter. (2) Fit the flowmeter body to the collars. And tighten the four bolts and nuts uniformly. (3) Check for leakage from the flange connections.
Horizontal Installation- (1) Insert two stud bolts in the bolt holes on the flowmeter shoulder to align the instrument body with the inner diameter of the adjacent piping. (2) Tighten all bolts uniformly and check that there is no leakage between the instrument and the flanges.
2. Flange Type
Use the stud bolts and nuts supplied with the flowmeter of the user. The gaskets should be supplied by the user.
3. Remote Type Converter
The converter is mounted on a 2-inch (60.5mm outer dia.) stanchion or horizontal pipe. Do not mount the converter on a vertical pipe. It makes wiring and maintenance difficult.

Resources
Yokogawa's digitalYEWFLO Reduced Bore Type Vortex Flow meter features a cast stainless steel body and a concentric reducer and expander that enable stable flow rate measurements in low-flow conditions. This expands the range of measurements that can be performed, from the higher flow rates down to the lower end of the flow span, which is normally difficult for Vortex Flow meters, and ensures stable and accurate flow rate output.
It is estimated that almost two thirds of oil discovered in the United States lies unrecovered trapped in porous formations. There are approximately 500,000 abandoned wells containing such oil. Because of this fact oil companies are constantly pursuing methods for the recovery of this oil.
