Yokogawa DY200-NXBBA2-0N/HT1 Digital YEWFLO Vortex Flow Meter
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
New functions with SSP (Spectral Signal
Processing) technology :
SSP is built into the powerful electronics of
digitalYEWFLO. SSP analyses the fluid conditions
inside digitalYEWFLO and uses the data to
automatically select the optimum adjustment for the
application, providing features never before
realized in a vortex flowmeter.
SSP accurately senses vortices in the low flow
range, providing outstanding flow stability.
Advanced Self-diagnostics :
The application condition, such as high pipeline
vibration and abnormal flow, is predicted and
High Accuracy :
±0.75% of Reading (Liquid)
(±0.5% of Reading : Typical Accuracy/ Non-Guaranteed)
±1% of Reading (Gas, Steam)
Wide Process Temperature Range :
High temperature version up to 450°C
Cryogenic version minimum –196°C
Simple Parameter settings :
Frequently-used selections grouped together in a
quick-access format decreases commissioning time.
Clear, Concise Indicator :
Simultaneous flow rate or temperature (Option) and
total flow rate along with process diagnosis
Dual output for Analog / Pulse:
Simultaneous output for flow rate or temperature
(Option) and pulse.
Alarm output, Status output (Flow switch)
An alarm signal output, in case alarm occurs.
No moving parts stainless steel detector : High
durable and safety.
Remote cable length 30m maximum.
Explosion proof construction, JIS / FM / CENELEC
