Overview
The Yokogawa DY vortex flowmeter is a product that combines on-site tested sensors and body components (installed in 200000 units) with digital electronic components containing SSP (Spectrum Signal Processing) technology.
Product Details
Yokogawa DY Vortex Flow MeterThe main values are DY015, DY025, DY040, DY050, DY080, DY100, DY150, DY200, DY250, DY300
Product Features
SSP (Spectrum Signal Processing))New features of technology:
SSP includes electronic components with * function in digital YEWFLOIn the middle. SSP analyzes the fluid situation inside the digital YEWFLO and automatically selects the adjustment corresponding to the operating condition based on the analysis dataProvide functions that traditional vortex flowmeters cannot achieve.
SSP can perceive vortices in the low flow range and provide ultra stableTraffic output.
2. * Self diagnostic function:
Predictable and display changes in application conditions, such as significant pipeline vibrationsAbnormal flow state, etc.
3. High precision:
± 0.75% of reading (liquid)
(± 0.5% of reading: Symbolic accuracy/not guaranteed)
± 1% of reading (gas, steam)
4. Liquid temperature range *:
High temperature type up to 450 ℃
Low temperature type -196 ℃
5. Easy parameter setting:
Frequently used choices can be combined into easily accessible formats to reduce the number of groupsState time.
6. Clear and concise display.
Can conveniently display instantaneous flow or temperature while diagnosing the display process(Purchase) and accumulated traffic.
7. Analog/pulse dual output:
Simultaneously output flow rate or temperature (optional) pulses.
8. Alarm output and status output (flow switch)An alarm signal output when an alarm occurs.
9. Stainless steel detector without moving parts: high durability and safety.
10. The remote cable length is 30m.
11. Explosion proof structure, JIS / FM / CENELEC ATEX (KEMA) /CSA/SAA (Explosion proof/Intrinsic Safety).
12. Communication functions include * FOUNDATION fieldbus, BRAN, and
HART protocol.
For detailed specifications of the FOUNDATION fieldbus protocol, please refer toGS 01F06F00-01E。
FOUNDATION is the registrar of FOUNDATION fieldbusMark.
HART is a registered trademark of the HART Communication Foundation.
