digitalYEWFLO High Temperature Version / Cryogenic Vortex Flow Meter

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.

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.

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.

 

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.

 

Features

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.

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.

Remote cable length up to 30m.

User-Friendly LCD Indicator

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.

 

Alarm output

An alarm signal notifies the operator of any issues, preventing inaccurate measurements.

Water and Steam Injection

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.

Overview:

Medir el consumo de energía es un factor importante en la búsqueda de mejorar la eficiencia energética. La medición eficiente y precisa es fundamental para determinar el exceso de uso, junto con una imagen exacta en dónde se usa el vapor. Las mediciones más precisas y confiables que se realizan, las decisiones más informadas pueden ser tomadas afectando los costos y la calidad del producto. Tradicionalmente, el método más común de medición de vapor es la placa de orificios y la técnica de medición de presión diferencial. Las áreas generales de preocupación con este tipo de medición son la susceptibilidad de la placa de orificios para introducir errores inmediatos, las relativamente permanente pérdidas de presión alta introducidas en el sistema por el orificio y el rango de medida pequeña, por lo general típicamente es 3:1.

El digitalYEWFLO con Diámetro Reducido Tipo Medidor de Flujo Vortex Modelo de Yokogawa cuenta con una estructura de acero inoxidable fundido y un reductor concéntrico y de expansión que permite realizar unas mediciones de flujo estables en condiciones de bajo flujo. Esto amplía la gama de mediciones que se pueden realizar, desde las velocidades de flujo más altas hasta el extremo inferior del intervalo de flujo, que normalmente es difícil para los medidores de flujo Vortex, y asegura una salida de velocidad de flujo estable y exacta.

Overview:

Se estima que casi dos tercios de petróleo descubierto en los Estados Unidos se encuentran atrapado en formaciones porosas. Hay aproximadamente 500,000 pozos abandonados que contienen dicho petróleo. Debido a este hecho las compañías petroleras están persiguiendo constantemente métodos para la recuperación de este petróleo.

Overview:

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.

Yokogawa Technical Report
Overview:

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.
