Yokogawa's vortex flowmeters are precision instruments designed to measure the flow rate of fluids, including gases and liquids.These meters operate by generating vortices (swirling patterns) in the fluid as it
passes over a bluff body within the flowmeter.These vortices are detected by sensors, and the frequency of these vortices is directly proportional to the flow rate.
Key Features and Specifications
High Accuracy:Vortex flowmeters offer excellent accuracy and repeatability, even under varying flow conditions.
Wide Flow Range:They can measure a wide range of flow rates, from low to high.
Bipolar Output: Provides a bipolar output signal, which is less susceptible to noise and interference.
Materials: Available in a variety of materials to suit different process conditions, including stainless steel, Hastelloy, and other corrosion-resistant alloys.
Process Connections: Can be configured with various process connections to fit different piping systems.
Diagnostics: Built-in diagnostics provide information about the health of the meter and help to optimize performance.
Advantages
No Moving Parts: Vortex flowmeters have no moving parts, which reduces maintenance requirements and increases reliability.
Wide Range of Applications:Suitable for a wide range of fluids and industries, including oil and gas, chemical processing, and power generation.
Low Pressure Drop: Minimal pressure drop across the meter, resulting in lower energy consumption.
Bipolar Output: Provides a more robust and reliable signal compared to unipolar outputs.
Precautions
Installation: Proper installation is critical for accurate measurements. Follow the manufacturer's instructions carefully.
Straight Pipe Runs:Sufficient straight pipe runs upstream and downstream of the meter are required to ensure accurate measurements.
Fluid Properties: The fluid properties (e.g., viscosity, density) can affect the meter's performance.
Process Conditions: Consider the process conditions, such as temperature and pressure, when selecting a meter.
Applications
Yokogawa vortex flowmeters are widely used in various industries, including:
Oil and Gas: Measuring the flow of crude oil, natural gas, and other hydrocarbons.
Chemical Processing: Monitoring the flow of chemicals and solvents.
Power Generation: Measuring steam and water flow in power plants.
Food and Beverage: Monitoring the flow of liquids and gases in food processing plants.
