DigitalYEWFLO Universal Vortex Flow Meter
Classification:
Key words:
- Product Description
-
- Commodity name: DigitalYEWFLO Universal Vortex Flow Meter
- Commodity ID: DigitalYEWFLO
The digital YEWFLO vortex flowmeter combines field-verified sensors with robust body components, leveraging a unique and powerful suite of digital technologies—such as Spectral Signal Processing (SSP), an innovation from Yokogawa Electric—in over 450,000 installations worldwide. Even under challenging process conditions, the digital YEWFLO vortex flowmeter delivers accurate, stable performance with exceptional reliability. Its advanced design not only enhances plant efficiency but also helps reduce operational costs.
- Achieve durability through simple design and construction.
- Provide diagnostic information under conditions such as external vibration interference, fluid fluctuations, vortex-induced blockages, or excessive buildup, enabling process analysis to yield accurate maintenance insights.
- Strong pipeline vibrations can affect the accuracy of vortex shedding frequency detection. The two piezoelectric elements installed in the DY vortex flowmeter feature a polarized structure, which enables them to effectively detect vibrations only in the horizontal direction—neither horizontal nor vertical vibrations are picked up. By adjusting the output of the piezoelectric elements, it’s possible to reduce noise caused by vertical vibrations.
- In the past, certain production conditions required manual adjustments to counteract noise caused by pipeline vibrations. Yokogawa Electric’s DY utilizes SSP to analyze the detected frequencies, allowing only the vortex shedding frequency to pass through a band-pass filter, thereby enabling accurate identification and elimination of noise. Even during flow fluctuations, SSP technology ensures that these objectives can still be achieved.
- Yokogawa Electric's DY utilizes standard communication protocols, such as the BRAIN protocol, HART 5 protocol, HART 7 protocol, and the FF Fieldbus protocol. This allows the DY to be quickly integrated into your existing systems.
- The universal DY vortex flowmeter comes in a variety of sizes, ranging from 1/2 inch to 16 inches. Depending on customer requirements, it is available in clamp-on or flanged designs (ANSI 150–900 class), among other options.
