Long-term reliability of the digitalYEWFLO series extends to the High Process Temperature and Cryogenic Vortex Flow Meter.
The High Process Temperature option measures process mediums at temperatures as high as 450 °C, ideal for high temperature superheated and saturated steam applications.
The Cryogenic option can measure process mediums at temperatures as low as -196 °C, ideal for low temperature applications such as liquid oxygen.
Our High Temperature / Cryogenic 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.
Durability through simple design and construction.
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.
SSP analyses the fluid conditions inside the vortex flowmeter and uses the data to automatically select the optimum adjustment for the application, providing features never seen before in a vortex flowmeter.
In addition, SSP accurately senses vortices in the low flow range, providing outstanding flow stability.
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.
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.
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.
Remote cable length up to 30m.
Simple parameter settings: frequently-used selections grouped together in a quick-access format decrease commissioning time.
Clear, concise indicator: convenient display of the simultaneous and total flow rates together with the process diagnosis.
An alarm signal notifies the operator of any issues, preventing inaccurate measurements.
Water and steam injection is a common method of oil recovery. The high temperature vortex flow meter is the ideal solution for this application due to its remote electrical housing, robust construction, and ability to withstand a wide temperature range. In addition, it provides inherent linear measurement, large turndown, and minimal pressure loss with a stable and reliable flow measurement.
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.
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.
Vortex flow meters utilize a fluid phenomenon in which frequencies of Karman vortex streets released from a shedder bar inserted in a flow are proportional to flow velocities.
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.
