Product Description

Yokogawa Digital Multivariable DY 150 Vortex FlowMeter

The Yokogawa Digital Multivariable DY150 Series Vortex Flowmeter represents a cutting-edge solution for precision flow measurement in industrial applications. Designed to deliver high accuracy and robust performance, this advanced flowmeter combines state-of-the-art digital signal processing with multi-variable measurement capabilities, enabling users to monitor flow rates alongside critical process parameters such as temperature and pressure. Engineered for versatility, the DY150 Series is ideal for demanding environments across oil and gas, chemical, power generation, and water/wastewater industries, where reliable data acquisition and operational efficiency are paramount.

Advanced Measurement Technology At the core of the DY150 Series is Yokogawa's proprietary vortex shedding principle, which leverages the Karman vortex street phenomenon to determine flow velocity. As fluid passes a bluff body within the meter, alternating vortices are generated at a frequency proportional to the flow rate. High-sensitivity sensors detect these vortices, while advanced digital algorithms process the signals to provide stable, repeatable readings. Unlike traditional vortex meters, the DY150 integrates multivariable sensing, allowing simultaneous measurement of volumetric flow, mass flow, temperature, and pressure—all from a single device. This eliminates the need for separate instrumentation, reducing installation complexity and costs.

Enhanced Accuracy and Rangeability The DY150 Series offers exceptional accuracy of ±1.0% of reading over a wide flow range, ensuring precise data across varying process conditions. Its expanded turndown ratio of 30:1 accommodates fluctuating flow rates, making it suitable for applications with dynamic operational demands. The meter's internal compensation algorithms adjust for changes in fluid properties, such as density variations caused by temperature or pressure shifts, further enhancing measurement reliability. This adaptability is particularly beneficial in steam, gas, and liquid applications where process conditions are inherently variable.

Digital Signal Processing and Communication Equipped with Yokogawa's proprietary digital signal processing (DSP) technology, the DY150 Series minimizes noise interference and improves signal stability, even in challenging environments with vibration or turbulent flow. The meter supports multiple communication protocols, including HART, FOUNDATION Fieldbus, and Modbus, enabling seamless integration into distributed control systems (DCS), programmable logic controllers (PLC), or asset management platforms. Real-time data transmission facilitates remote monitoring, predictive maintenance, and process optimization, empowering operators to make informed decisions.

Rugged Design and Environmental Resilience The DY150 Series features a durable construction designed to withstand harsh industrial conditions. Available in flanged, wafer, and dual-flanged configurations, the meter accommodates pipe sizes ranging from 1.5 to 30 inches, with materials tailored to specific media types, including stainless steel for corrosive environments. Its IP67-rated housing ensures protection against dust and water ingress, while optional certifications (e.g., ATEX, IECEx) enable deployment in hazardous areas. The meter operates reliably in extreme temperatures (-40°C to +400°C) and pressures up to ASME Class 600, maintaining performance in critical applications.

Simplified Installation and Maintenance Yokogawa has prioritized ease of use in the DY150 Series design. The meter requires minimal straight-run piping requirements, reducing installation constraints and space limitations. Built-in self-diagnostic functions continuously monitor sensor health, signal quality, and process integrity, alerting operators to potential issues before they escalate. Additionally, the non-intrusive configuration interface allows for quick setup and calibration without removing the meter from the pipeline, minimizing downtime and maintenance costs.
