Product Description
Digital YEWFLO Vortex Flowmeter (DY)
1. Product introduction
The digital YEWFLO vortex flowmeter combines the field proven sensor and body assembly used in more than 400, 000 units installed worldwide with a unique and powerful combination of digital technology that includesspectral 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
2. Features
- New functions with Spectral Signal Processing (SSP) technology
SSP analyses the fluid conditions inside the digitalYEWFLO vortex flowmeter and uses the data to automatically select the optimum adjustment for the application, providing features never seen before in a vortex flowmeter.
SSP accurately senses vortices in the low flow range, providing outstanding flow stability.
- Advanced self-diagnostics
Application conditions such as high pipeline vibration and abnormal flow are predicted and indicated.
- High accuracy
± 0.75% of reading (liquid)
± 1.0% of reading (gas, steam)
- Wide process temperature range
High temperature version up to 450 deg C
Cryogenic version minimum -196 deg C
- 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
- Dual output for analog/pulse
Simultaneous output for flow rate and pulse
- Alarm output
An alarm signal is output when an alarm occurs.
- BRAIN/HART communication and key switches for human-machine interface
- NACE compliant
- NAMUR 43 compliant
- Remote cable length up to 30m
