Vortex flow meter pros and cons
Overall, vortex flow meters are durable, simple sensors with low setup cost. However, they're also sensitive to contamination and vibration and are ineffective for high viscosity, low velocity applications. Here are the detailed pros and cons of these flow meters:
Advantages of vortex flow meters
Benefits and features of these flow meters include:

- Versatility These flow meters are highly versatile, capable of effectively measuring the flow of liquid, gas, or steam. This adaptability makes them invaluable in diverse industrial settings.
- Durability This model has few moving parts. This design simplicity means there's less room for failure, resulting in low maintenance and a reduced risk of malfunction.
- Independence from temperature and pressure fluctuations. Vortex flow meters can measure flow rates independently of temperature and pressure fluctuations within the system. They provide consistent and reliable data even in dynamic conditions.
- No conductivity requirement Unlike some flow measurement technologies, vortex meters do not require a specific level of conductivity in the flow media. This makes them a great solution for deionized water systems.
- Low setup cost: These meters are cost-effective to install. That feature makes them especially attractive for businesses looking to improve flow measurement without a significant financial outlay.
Vortex flow meter disadvantages
Some vortex flow meter limitations to consider are:
- Sensitivity to contamination Vortex flow meters are not suitable for applications involving contaminated flow media. Any foreign particles or inclusions can interfere with the accuracy of the measurement.
- Unsuitable for high viscosity or low flow velocity applications Vortex flowmeters are ineffective in situations with high viscosity or very low flow velocity. Consider coriolis mass or oval gear flow meters for these applications.
- Susceptibility to vibration High levels of vibration in the system can lead to false interpretations of increased flow rates. This is a significant limitation in environments with substantial vibrations.
- Potential clogging Liquid polymerization can lead to sensor clogging. However, some models have extra features that overcome this limitation.
How vortex flow meters work
Similar to how a rock in a stream will create vortices downstream, the bluff body in these types of meters acts as a vortex generator. The amount of vortex shedding off the bluff body is proportional to the flow rate in the same way that higher velocity of a stream will create rapids. The intensity of the vortices created in the system can be measured to determine the velocity of the liquid, gas, or vaporous flow media.
Best applications for vortex flow meters
- Water based liquids (>=95% aqueous) These flow meters are ideal for aqueous flow media due to their low-viscosity. Since there is no conductivity requirement of the flow media, this is a great option for deionized water systems.
- Cooling circuits Vortex flow meters are well-suited for monitoring cooling circuits, providing accurate measurements without the need for extensive maintenance. They also work well in a wide range of operating temperatures.
- Low-cost systems Businesses with budget constraints can benefit from the affordability and reliability of vortex flowmeters.
- Small pipe diameters Vortex flow meters are ideal for systems with pipe diameters of 6 inches or less thanks to their compact design and simplicity.
Choosing the right vortex flow meter
- Contamination If your application involves the risk of contamination in the flow media, opt for a model equipped with screens to prevent sensor clogging.
- Temperature and pressure ranges Ensure the model you choose can operate within your system's temperature and pressure ranges. These factors impact accuracy and reliability.
- Additional features Some vortex flow meters offer supplementary data, such as temperature readings. If this is essential for your application, look for a model that provides this capability.
