Japan Yokogawa digitalYEWFLO Vortex Flowmeter
Product Introduction
The Japan Yokogawa digitalYEWFLO Vortex Flowmeter (Standard Type),
available in models Dy025, Dy050, Dy100, and Dy200, is a
high-performance flow measurement device designed to measure the
flow rate of liquids, gases, and steam. Featuring a simple and
robust structure with no moving parts, it delivers exceptional
reliability and durability, making it suitable for a wide range of
industrial applications. Its installation is straightforward,
requiring only two upstream and downstream connections, and the
sensor’s frequency detection design ensures zero flow outputs zero
frequency, eliminating the need for zero adjustment. With support
for 20mA output and various communication protocols, it integrates
seamlessly into industrial control systems.
Features
Versatile Measurement: Capable of measuring flow rates of liquids,
gases, saturated steam, and superheated steam (note: avoid
multi-phase flow and adhesive fluids).
Robust Construction: A simple, moving-part-free design ensures high
reliability and durability, reducing maintenance needs and
extending service life.
Easy Installation: Requires only two upstream and downstream
connections for piping installation, simplifying setup processes.
No Zero Adjustment: The sensor detects frequency and outputs zero
frequency at zero flow, eliminating the need for manual zero
adjustment.
Wide Temperature Range: Operates in process temperatures from -29
to 250 °C, adapting to diverse industrial conditions.
Flexible Pressure Handling: Process pressure up to -0.1 MPa (per
flange rating), suitable for various pressure environments.
Multiple Diameter Options: Wafer type available in 15–100 mm;
flange type in 15–400 mm, accommodating different piping sizes.
High Accuracy:
±0.75% of reading for liquids (depending on Reynolds number)
±1.0% of reading for gases and steam (depending on flow velocity)
Flexible Outputs: Offers analog output and transistor contact
output, with simultaneous output capability for seamless
integration with external devices.
Rich Communication: Supports HART 7 / HART 5, BRAIN, and FOUNDATION
fieldbus, enabling easy system integration and remote monitoring.
Explosion Protection: Available with multiple explosion-proof
certifications, including TIIS Ex d, FM Ex d / Ex ia, ATEX Ex db /
Ex ia, CSA Ex d / Ex ia, and IECEx Ex db / Ex ia, ensuring safety
in hazardous areas.
