VY Series Overview
Digitalization
Supporting Efficient and Planned Plant Operations
In a plant where a large number of equipment is in operation, efficient and systematic maintenance activities are required according to the equipment condition.
The VY series equip with complete device self-diagnosis function including the shedder bar and sensor elements by further advanced the digitalization of internal signals. This improves reliability, including for safety instrumentation loops (complies with SIL2). The remote maintenance function allows easily checking the health of the equipment from the computer in the instrument room without the need to go to the site. Yokogawa's vortex flowmeter has been well-established as maintenance-free. With enhanced self-diagnosis and remote maintenance functions, it realize condition-based maintenance of the vortex flowmeter.
Inheritance
Stable Measurement and High Maintainability
The VY series inherits the reliable and proven detection structure unique to the YEWFLO series.
It is the only removable vortex shedder bar with two flow sensors and one built-in temperature sensor. This structure brings robustness, long-term stability, short face-to-face length, and shortened upstream straight pipe length.
Even if maintenance is required, eg. due to process upset, there is no need to remove the entire flowmeter from the pipe. Partial cleaning and replacement of the vortex shedder bar is possible. In addition, by performing digital signal processing with a unique structure equipped with two sensor elements, pipe vibration is eliminated effectively.
Since the unique detection structure and face-to-face length are compatible with the previous YEWFLO series, VY series can be installed in the same place without additional work for piping.

Vortex Flow Meters - Principle of Operation
Vortex Flow Meters use the Von Karman Effect to measure the rate of flow of a fluid or gas.
What Is the Von Karman Effect?
Early in the 20th century, a Hungarian-American mathematician and physicist, Theodore von Karman, discovered that a fluid or gas flowing perpendicularly pass a bluff body would generate alternating vortices on both sides of the body. The path of these vortices is called the von Karman vortex street.
Von Karman found that if the frequency of these vortices was measured, that the frequency is proportional to the flow velocity that is generating the vortices. This frequency is called the Karmen Vortex Frequency. The relationship of the frequency and the flow velocity can be mathematically expressed with the following formula:
From the equation, we can see that the frequency is proportional to the velocity. If we can measure the frequency (f), know the Strouhal number (St), know the shedder bar width (d); we can solve for v (velocity).
How Do We Measure the Frequency of the Vortices?
As vortices form and pass the shedder bar (the bluff body), they create a low pressure as compared to the rest of the fluid. This low pressure produces a differential pressure (dp) across the shedder bar. The high pressure side of the dp exerts stress on the shedder bar in the direction of the low pressure. As the location of the low pressure side alternates due to the vortices switching from side-to-side, the change in direction of the exerted force causes the shedder bar to oscillate. This oscillation is equal to the Karmen Vortex Frequency.
There are several methods in the marketplace to measure the oscillation. Diaphragms or capacitance sensors are two of the more common; but, the best method is the use of Piezo-electric crystal sensors. These sensors, when compressed, produce an electric signal that can be sent to the Flow meter's electronics. Now that the Karmen Vortex Frequency is measured (and we know the St and d), the flow meter electronics can do simple calculations to determine volumetric flow through the pipe.
What Are the Advantages of Using Vortex Flow Meters?
- High Accuracy
The accuracy of the vortex flow meter is ±1% (pulse output) of the indicated value for both liquids and gases and is higher compared to orifice flow meters. For liquids, an accuracy of ±0.75% is available depending on the fluid type and their conditions. - Wide Rangeability
Rangeability is defined as the ratio of maximum value to minimum value of the measurable range. It is broad rangeability the allows vortex flow meters to operate in processes where the measuring point may fluctuate greatly. - Output Is Proportional to Flow Rate
Since the output is directly proportional to the flow rate (flow velocity), no square root calculation is needed, while orifice flow meters require square root calculations. - No Zero-point Fluctuation
Since frequency is output from the sensor, zero-point shift does not occur. - Minimal Pressure Loss
Since only the vortex shedder is placed in the pipe of the vortex flow meter, the fluid pressure loss due to the small restriction in the flow piping is small compared with flow meter a having an orifice plate.
Combining Noise Reduction and Spectral Signal Processing (SSP) to provide an accurate and stable measurement.
Technical Information - Sensing Technology -
Signal Processing (SSP: Spectral Signal Processing)
VY series's SSP Function Provides Enhanced Vibration Immunity and Advanced Diagnostics
VY series is a maintenance-free flowmeter. It has a circuit for analyzing the frequency of detected signal and allows only vortex frequency to pass through the segmented band-pass-filter, thereby accurately identifying and eliminating noise. The Spectral Signal Processing (SSP) function of VY series only outputs the appropriate vortex frequencies, even under fluctuating flow rate conditions.
Noise Reduction
Noise caused by strong piping vibration may affect the accuracy of the vortex frequency detection. The two piezoelectric elements installed in the VY series 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.
Technical Information - Straight Pipe Length -
Straight Pipe Length According to Installation Situation
Vortex flowmeters generally affect flow measurement accuracy when the flow velocity distribution in the pipe is biased.
Necessary straight pipe length and main points are shown along with typical installation examples.
Straight Pipe
Secure at least 10D upstream and 5D downstream.
Reducer Pipe
Secure at least 5D upstream and 5D downstream.
Expander Pipe
Secure at least 10D upstream and 5D downstream.
Single Bent Pipe
Secure at least 10D upstream and 5D downstream.
Double Bent Pipe in the Same Plane
Secure at least 10D upstream and 5D downstream.
Double Bent Pipe in Another Plane
Secure at least 20D upstream and 5D downstream.
Valve Position and Straight Pipe Length
Install the valve on the downstream side of the flowmeter. The upstream straight pipe length dependent on the element located on the upstream such as reducer/expander, bent and etc., refer to description as above. Keep 5D or more for downstream straight pipe length.
In case the valve has to be installed on the upstream of the flowmeter, ensure the upstream straight pipe length to be 20D or more, and the downstream straight pipe length be 5D or more.
Technical Information - Mounting Attitude -
If the pipe is always filled with fluid, the mounting direction does not matter whether it is horizontal, vertical or inclined.
However, in the case of horizontal and inclined, be sure to install the terminal box or converter above the piping position in order to avoid flooding.
