Vortex Flow Meter
A vortex meter is a type of volumetric flow meter that makes use of a natural phenomenon that occurs when a liquid flows around a bluff object. Vortex flow meters operate under the vortex shedding principle, where vortices (or eddies) are shed alternately downstream of the object. The frequency of the vortex shedding is directly proportional to the velocity of the liquid flowing through the meter.

Advantages of Vortex Flow Meter
Versatility
Vortex flow meters can measure the flow of liquids, gases, and steam, making them versatile for various applications.
High Accuracy and Repeatability
These meters provide accurate and repeatable flow measurements with minimal drift over time, making them reliable for critical processes.
Low Maintenance
With no moving parts, vortex flow meters require less maintenance compared to other flow meters like turbine or positive displacement meters. This also reduces the risk of wear and tear, increasing their lifespan.
Wide Range of Flow Rates
Vortex flow meters are capable of measuring a wide range of flow rates, from low to high velocities, which makes them suitable for different industrial requirements.
Unaffected by Fluid Properties
The measurement accuracy of vortex flow meters is not significantly affected by changes in fluid properties such as viscosity, density, or temperature, making them robust for varying process conditions.
Suitable for High-Temperature and High-Pressure Applications
Many vortex flow meters are designed to withstand high temperatures and pressures, making them ideal for applications involving steam and hot fluids.
Types of vortex flow meter
Vortex Shedding Flow Meter
This is the most common type, relying on vortex shedding behind a bluff body. The frequency of vortices corresponds to the flow rate, providing accurate and reliable measurements.
Insertion Vortex Flow Meters
These meters are inserted directly into the pipeline, making them cost-effective for large pipes.
Inline Type Meter
Inline meters are installed directly in the pipeline, offering high accuracy and stability.Detects vortices across the full flow profile for accurate readings.
Multivariable Vortex Flow Meters
These meters measure multiple parameters, such as flow rate, pressure, and temperature, in a single device.Combines vortex shedding with additional sensors for multi-parameter monitoring.
Vortex Precession Swirl Meter
This type uses a swirling flow pattern rather than a bluff body to generate vortices.Measures flow based on the precession of vortices in a swirling flow.
Applications of Vortex Flow Meter
Oil and Gas Industry
Vortex flow meters are extensively used in the oil and gas industry for measuring the flow of natural gas, steam, and liquids in various processes. They are particularly useful in measuring steam flow for enhanced oil recovery processes.
Chemical and Petrochemical Industry
In chemical plants, vortex flow meters are employed for the flow measurement of various chemicals, gases, and liquids. Their robustness and compatibility with different fluid types make them an excellent choice for such applications.
Water and Wastewater Management
Vortex flow meters are commonly used in water and wastewater treatment plants to measure the flow of water, slurries, and other liquids. They are especially useful for monitoring flow in large pipes and open channels.
HVAC and Building Automation
In heating, ventilation, and air conditioning (HVAC) systems, vortex flow meters are used to measure the flow of water, steam, and air for efficient energy management and system optimization.
Power Generation
Vortex flow meters are widely used in power plants to measure the flow of steam and cooling water, as well as natural gas, in turbines and boilers. They are particularly effective in high-temperature and high-pressure applications.
Food and Beverage Industry
In the food and beverage industry, vortex flow meters are used for measuring the flow of liquids such as water, juices, and other fluids. They are preferred for their sanitary designs and compatibility with clean-in-place (CIP) processes.
Pharmaceutical Industry
Vortex flow meters are used to measure the flow of various liquids and gases in pharmaceutical manufacturing processes. Their accuracy and reliability help maintain precise control over fluid flow in critical applications.
Vortex Flow Meter Working Principle
Fluid Flow
When a fluid passes through a pipeline, it encounters the shedder bar of the vortex flow meter. As the fluid flows around the bar, alternating vortices are created as the fluid separates from the bar’s surface.
01
Vortex Shedding
As the fluid moves past the shedder bar, vortices form in a consistent, alternating pattern on each side of the bar. The frequency of these vortices depends on factors like the fluid’s density, viscosity, and the size and shape of the shedder bar.
02
Pressure Fluctuations
The vortices cause pressure fluctuations in the fluid as they are shed from the bar. A sensor mounted near the shedder bar detects these variations in pressure.
03
Signal Processing
The sensor converts the pressure changes into an electrical signal. This signal is then analyzed by the flow meter’s electronics.
04
Flow Rate Calculation
By correlating the detected vortex shedding frequency with the fluid properties and meter design specifications, the electronics can accurately determine the flow rate.
05
Choose the Right Location: Select a straight pipe section with minimal turbulence. Aim for at least 10 pipe diameters of straight run upstream and 5 pipe diameters downstream from the meter.
Consider Flow Path: Ensure the vortex flow meter is installed in a section where the flow path is fully developed and stable.
Proper Orientation: Install the meter according to the manufacturer’s specifications, paying attention to flow direction indicators.
Avoid Vibration: Mount the meter securely to minimize external vibrations that could affect vortex formation.
Account for Pressure Drop: Consider the pressure drop introduced by the meter when designing your system.
Regular Inspections
Conduct visual inspections of the meter and surrounding piping periodically to check for any signs of wear or damage.
Clean Sensor
Keep the vortex sensor clean and free from buildup that could interfere with vortex detection.
Check Signal Quality
Monitor the signal quality regularly. A weak or erratic signal may indicate issues with vortex formation or detection.
Verify Calibration
Perform periodic calibration checks to ensure continued accuracy across the flow range. Follow the manufacturer’s recommended calibration schedule.
Update Firmware:
Keep the meter’s firmware up-to-date to benefit from the latest features and performance improvements.
Troubleshooting Common Issues
Low Flow Readings: Check for partial blockages or buildup on the bluff body.
Erratic Readings: Look for sources of external vibration or pulsating flow.
Zero Flow Reading: Verify that the pipe is full and that the flow rate is above the meter’s minimum detection threshold. By following these installation and maintenance guidelines, you can ensure your vortex flow meter provides accurate and reliable measurements for years to come. Regular care and attention will maximize the meter’s performance and extend its operational life.
