Vortex flowmeters
Vortex flowmeters are precision instruments designed to measure the flow rate of liquids, gases, and steam in industrial pipelines.

Vortex flowmeters are precision instruments designed to measure the flow rate of liquids, gases, and steam in industrial pipelines. They operate on the principle of the von Kármán vortex street, where a bluff body placed in the flow path generates alternating vortices. The frequency of these vortices is directly proportional to the flow velocity, allowing for accurate volumetric flow measurement. Key technical specifications include a wide turndown ratio (typically 10:1 to 20:1), accuracy classes of ±0.5% to ±1.0% of reading, and compatibility with process temperatures from -40°C to +400°C and pressures up to 400 bar. These meters are available in various line sizes (DN15 to DN300) and materials such as stainless steel (316L) and Hastelloy, with options for integral or remote electronics. They often feature HART, Modbus, or Profibus communication protocols for integration into distributed control systems (DCS) and programmable logic controllers (PLC).
Vortex flowmeters are widely deployed in sectors such as oil and gas, chemical processing, power generation, water and wastewater treatment, and HVAC systems. They are ideal for measuring steam (saturated and superheated) in boiler systems, compressed air in industrial utilities, and process fluids in refineries and chemical plants. Their robust design makes them suitable for harsh environments, including hazardous areas with ATEX or IECEx certifications. Typical installations include pipe racks, skid-mounted units, and direct integration into existing pipeline infrastructure for continuous process monitoring and control.
Within our catalog, subcategories include inline vortex flowmeters, insertion vortex flowmeters, and sanitary vortex flowmeters for hygienic applications. Key article codes follow a structured format: VFM-XXXX-YY, where XXXX denotes the nominal diameter (e.g., 0050 for DN50) and YY indicates the output type (e.g., 4A for analog 4-20 mA with HART, or 2P for pulse output). For example, VFM-0100-4A represents a DN100 vortex flowmeter with analog output. Other relevant codes include VFM-0150-2P for pulse output and VFM-0200-MB for Modbus communication. These are primary measurement devices, not accessories like gaskets or mounting kits.
