digitalYEWFLO Multivariable Type Vortex Flowmeter
(DY-MV)

The digitalYEWFLO vortex flowmeter combines the field proven sensor and body assembly used in more than 260,000 units installed worldwide with a unique and powerful combination of digital technology that includes spectral signal processing (SSP), a Yokogawa innovation. The digitalYEWFLO vortex flowmeter 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

Features: digitalYEWFLO multivariable Vortex Flowmeters

Multivariable Type: option code /MV

• Resistance temperature sensor built into vortex shedder bar
• User selectable Flow, Temp, Total and other displays
• Mass flowrate calculated using temperature readings and steam table data
• Able on its own to output mass flowrate

<How can the density of steam be calculated from a temperature reading? >
A steam table provides data on the temperature, pressure and density of steam and is provided by a certification body such as the ASME. The saturated steam curve shows the steam saturation point for each pressure/temperature level. The digitalYEWFLO converter calculates the mass flowrate using the density figure from the steam table. With its Spectral Signal Processing system, the digitalYEWFLO is able to accurately measure fluctuations in temperature.
- With superheated steam, density is calculated as a fixed pressure value that includes the superheated temperature value.

With the totalization function, energy consumption data collected over a period of time can be stored in memory and used to devise measures for reducing energy consumption.

EJA Pressure/ Differential Pressure Transmitters

The DPharp EJA Series is a best-selling differential pressure transmitter which incorporates our high accuracy resonating pressure (HARP) silicon sensor, a field-proven Yokogawa technology that is intelligent and offers ultra-high performance. This transmitter's compact and light weight design has been achieved without compromising performance or service life. The digital principle of the sensor provides repeatability and stability that is superior to analog sensor designs and is virtually immune to the effects of vibration, temperature, static pressure, and overpressure events.

This high performance differential pressure transmitter can be used to measure liquid, gas, or steam flow as well as liquid level, density and pressure.
