For measuring the volume and mass flow of liquids, gases and steam
VideoMultiple industries03.12.2024
This measuring principle is based on the fact that turbulence forms downstream of obstacles in the flow, such as a bridge pier.
Inside each vortex flowmeter, a bluff body is located in the middle of the pipe. As soon as the flow velocity reaches a certain value, vortices form behind this bluff body are detached from the flow and transported downstream. The frequency of vortex shedding is directly proportional to the mean flow velocity and thus to the volume flow.
The detached vortices on both sides of the bluff body generate alternately a local positive or negative pressure that is detected by the capacitive sensor and fed to the electronics as a primary digital, linear signal.

Advantages of vortex flowmeters at a glance
Universally suitable for measuring liquids, gases and steam
Largely unaffected by changes in pressure, density, temperature and viscosity
High long-term stability: no zero-point drift, lifetime K-factor
No moving parts
Little pressure loss
Easy installation and commissioning
Large turndown of typically 10:1 to 30:1 for gas/steam, or up to 40:1 for liquids
Wide temperature range: –200 to +400 °C (–328 to +752 °F) (450 °C / 842 °F on demand)
