Principle of measurement and measuring method of vortex flow meters

The vortex flow meter operates based on a physical phenomenon known as the Kármán vortex street. An obstruction in the gas flow causing periodic vortices as the gas flows. These vortices are detected by an ultrasonic field in the sensor head and their frequency is directly related to the flow velocity. This allows the flow rate the precisely determined even under difficult conditions.

A particularly practical feature is that measurements are possible even at very low flow velocities starting at 0.5 m/s and maintaining their accuracy at high velocities as well.

A key advantage is its independence from external factors. Pressure, temperature, viscosity or the composition of the gase have virtually no effect on the results. This ensures that the vortex flow sensor remains reliable even in processes where operating conditions frequently change or fluctuate. It is precisely this stability that makes it a reliable solution for a wide variety of industrial applications. 

Höntzsch vortex meter: Vortex flow sensor

Advantages of the vortex technology

Vortex flow sensors a designed with no moving parts, making them resistant to wear and significantly reducing maintenance requirements. In addition, the materials used are corrosion-resistant and can withstand even aggressive gases. Even if condensate forms or the gas contains particles, the sensor continues to deliver accurate measurment results.

This sets the vortex technology apart from other measuring methods, which often cause problems under such conditions. Furthermore the sensors are capable of detecting bidirectional flows, meaning that the direction of the gas flow is also detected. This is an essential safety feature, for instance when determining flow velocity in tunnels and shafts.

Applications and industry solutions for flow rate sensors

The applications for Höntzsch Vortex flow meters are extremely diverse, ranging from energy and anvironmental technology to highly sensitive safety areas. The broad spectrum of applications make them a reliable solution when it comes to precisely measuring flow rates and efficiently monitoring processes. 

The strength of this technology is particularly evident in the measurement of biogas, sewage gas and landfill gas. In these appliactions flow velocities are often very low, making them difficult to be measured with conventional devices. An explosion-proof Vortex flow sensor allows even the smallest quantities to be measured reliably. Even when the gas composition changes during the process or the gas contains particles and condensate, the measurement result remains stable and precise. 

In industrial processes, such as in waste-to-energy plants, RTO/RNV systems or cement plants, the precise measurement of exhaust gas flows is critical. Vortex technology meets the requirements of regulatory standards.

In critical processes involving aggressive or explosive gases, such as flare gases, Vortex technology delivers outstanding stability, explosion protection (ATEX/CSA), and the highest level of measurement reliability. Vortex VA sensors are suitbale for use up to SIL 3 and meet the highest safety and reliability requirements. They are used in nuclear power plants, final repositories and other safety-critical areas.

Other applications:

  • Chemical industry and petrochemistry
  • Engine test benches
  • Safety-relevant applications

This versatility makes Höntzsch Vortex flow meters a universally applicable tool for a wide variety of industries. Contact us today to learn how Vortex flow meters can optimize your processes.

Designs and models of Vortex Flow Meters

Höntzsch Vortex flow meters are available in various designs, allowing them to be flexibly adapted to the specific application. For larger pipelines with diameters of 80 mm or more vortex insertion probes are available that can be used in both fixed and portable appplications. For smaller pipe diameters, vortex measuring tubes are ideal, delivering precise results starting at an inner diameter of 24 mm. 

Combination probes offer a particularly practical solution, as they measure both flow velocity and temperature. This allows two important parameters to be monitored with a single device. Regardless of the design, Vortex sensors are engineered to provide reliable mreasurements in gases and gas mixtures. 

If you're looking for a measuring device that precisely meets your requirements, offers a long service life and ensures maximum safety, then Höntzsch's Vortex flow meters a re the right choise. We'd be happy to advice you personally to help you find the right design for your application.
