Vortex shedding flow meters are a special set of tools that give us a way to measure liquids as they flow, although using tools to measure the way liquids move is complicated. Such flow meters generate a ‘vortex’ that is a swirling motion, in the liquid as it flows in a pipe. By studying how these vortices form and shed from an object — a particular kind of object known as a bluff body — engineers can determine how much liquid is traveling through the pipe.
Vortex shedding flow meters operate according to a principle called the “Kármán Vortex Street” to measure the flow of fluids. This results in a regular formation of vortices as liquid passes over the bluff body. This would allow us to estimate the density in the same way as they do with an hourglass, where once we know how many vortices have been launched in a given period of time, we can calculate how many have been released per minute and thus the flow rate of the liquid.
” Vortex shedding flow meters are intelligent! As the fluid flows in the pipe, it encounters the bluff body. This object introduces flow perturbations; vortices start and are shed at a regular interval. By keeping track of these vortices, the flow meter can tell us how quickly the liquid is moving.
Vortex shedding flow meters offer several advantages. One great thing about them is how precisely they can measure the flow rate of liquids. They’re also remarkably easy to install and maintain, which is why they’re widely used across a range of industries. Futhermore, vortex shedding flowmeters are capable of being used with a variety of liquids and are therefore useful flow measuring devices.

Various forms of vortex shedding flow meters can also be used in different applications. For instance, insertion vortex shedding flow meters are perfect for larger pipes where installing a regular flow meter is impractical. In line vortex shedding flow meters are designed for small pipes of limited space. There are certain applications where one may be more appropriate over another.
In order for vortex shedding flow meters to remain dependable, accurate measurements, they need to be maintained and inspected regularly. That means a search for any sheaf of dirt, any blockages that might trip up the mechanics of the flow meter. 0 Callia 440 9 10 Calibration helps to ensure that a flow meter measures correctly and can also manage the condition of the liquid passing through the flow meter in the state in which the liquid will pass after fabrication.
