SSP (Spectral Signal Processing) technology:
SSP is built into the powerful electronics of digital YEWFLO. SSP analyses the fluid conditions inside digital YEWFLO 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.
Self-diagnostics:
The application condition, such as high vibration of the piping and pulsating flow, is predicted and indicated.
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 aquick-access format decreases commissioning time.
Clear, Concise Indicator:
Simultaneous flow rate or temperature (Option: /MV)and total flow rate along with process diagnosis conveniently displayed.
Dual output for Analog / Pulse:
Simultaneous output for flow rate or temperature(Option: /MV) 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.
Signal cable length is up to 30m.
Explosion proof construction, TIIlS / FM / ATEX/ CSA/ SAA (Intrinsically safe), IECEx.
