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.

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.
Measuring energy consumption is an important factor in the quest to improve energy efficiency. Efficient and accurate metering is paramount to determining excess use, along with an accurate picture of where the steam is being used. The more accurate and reliable measurements that are made, the more informed decisions can be taken that affect costs and product quality. Traditionally the most common method of steam metering is the orifice plate and differential pressure transmitter technique. General areas of concern with this type of measurement are the orifice plate's susceptibility to wear introducing immediate inaccuracies, the relatively high permanent pressure losses introduced into the system by the orifice place and the small measuring range, typically 3:1.
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.
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.
