Product Description

Product Description

Yokogawa DY40 Vortex Flowmeter Product Introduction Comprehensive Overview for Industrial Measurement Solutions
1. Product Overview
The Yokogawa DY40 Vortex Flowmeter is a high-precision flow measurement instrument designed for industrial applications involving liquids, gases, and steam. Leveraging the proven Kármán vortex street principle and advanced Spectrum Signal Processing (SSP) technology, this device ensures reliable performance even in harsh operating conditions. With over 450,000 installations globally, the DY series has established itself as a benchmark for stability, accuracy, and durability in flow measurement.
The DY40 model, part of Yokogawa's digitalYEWFLO lineup, is tailored for mid-sized pipelines (40mm nominal diameter) and supports a wide range of industrial processes, including chemical, power generation, and oil & gas industries. Its robust design minimizes pressure loss and enhances operational efficiency while reducing lifecycle costs.
2. Working Principle
The DY40 operates based on the Kármán vortex effect, where a bluff body (vortex shedder) placed in the fluid flow generates alternating vortices downstream. The frequency of these vortices is directly proportional to the flow velocity, enabling precise volumetric flow calculation.
Key Formula: f=St⋅vdf=dSt⋅v Where:
ff: Vortex frequency
StSt: Strouhal number (dimensionless coefficient)
vv: Flow velocity
dd: Width of the vortex shedder
The DY40 employs piezoelectric sensors to detect vortices. These sensors convert mechanical stress from pressure fluctuations into electrical signals, which are then processed by Yokogawa's proprietary SSP technology to eliminate noise and ensure measurement integrity.

3. Key Features

3.1 Advanced Signal Processing (SSP Technology)
Noise Reduction: Dual piezoelectric elements with polarized structures cancel out vertical and horizontal pipeline vibrations, ensuring accurate frequency detection.
Adaptive Filtering: SSP dynamically analyzes fluid conditions and applies real-time adjustments via bandpass filters, enabling stable measurements even in low-flow or turbulent scenarios.
3.2 High Accuracy & Repeatability
Accuracy: ±0.75% of reading (liquids), ±1% (gases/steam).
Repeatability: ±0.2% of reading, ensuring consistency across long-term operations.
3.3 Wide Operating Range
Fluid Temperature:
Standard: -40°C to +260°C
High-Temperature Option: Up to +450°C
Low-Temperature Option: Down to -200°C.
Pressure Range: -0.1 MPa to flange-rated pressure (e.g., ANSI 150~2500#).
3.4 Robust Construction
Material: Stainless steel sensor with no moving parts, ensuring resistance to corrosion and wear.
Certifications: Complies with NACE MR0175, NAMUR NE43, and international explosion-proof standards (ATEX, FM, CSA).
3.5 Smart Functionality
Dual Outputs: Simultaneous analog (4-20 mA) and pulse signals for integration with PLCs or SCADA systems.
Self-Diagnosis: Alerts for pipeline vibration, flow anomalies, or sensor fouling, reducing unplanned downtime.
Flow Switch Function: Programmable relay output for low-flow alarms or process control.
