Yokogawa DY200-NBLBD-2N Digital Vortex Flowmeter 4-20mA Output

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.
