Key Features
Versatility
Capable of measuring almost any fluid—including steam, aggressive chemicals, gases, and non-conductive liquids.
No Moving Parts
Built without gears or impellers, drastically reducing wear and tear, and requiring minimal maintenance.
Process Independence
Output remains largely unaffected by changes in fluid viscosity, density, temperature, or pressure.
Wide Turndown Ratio
Delivers an excellent rangeability, maintaining high accuracy even during fluctuating flow rates.
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.
Multivariable Vortex Flow Meters
These meters measure multiple parameters, such as flow rate, pressure, and temperature, in a single device.

Applications
Food & beverage
In food production, maintaining accurate flow control is essential for product consistency and safety. Inline type meters are often used to measure liquid ingredients, while multivariable vortex flow meters help monitor temperature and pressure simultaneously.
Chemical & petrochemical
The chemical industry requires robust, inline type meters to handle aggressive fluids. Vortex shedding flow meters are widely used for their durability and accuracy in monitoring chemical flows.
Energy industries
Energy plants need accurate flow data to optimize efficiency. Insertion vortex flow meters are ideal for large pipelines, while vortex precession swirl meters help measure gas flows in power generation.
Metallurgy
In metal production, precise flow measurement is critical for controlling cooling and heating processes. Inline vortex flow meters provide stable readings even in harsh conditions.
