Vortex Flow Meter for Gas, Steam and Liquid

The WAFS 1101 vortex flow meter is based on the Karman vortex principle to measure gas, steam, or liquid volume flow.

Its simplified structure, high reliability, and strong anti-pollution performance make it suitable for demanding industrial applications.

Integrated temperature and pressure sensing enables automatic density compensation to calculate mass flow using standard algorithms.

With digital spectrum analysis (DSA) and a high-sensitivity dual vortex sensor, the meter improves low-flow performance and helps reject vibration and electromagnetic disturbances.

Protection code: IP67. Explosion-proof structure is available for harsh environments (as applicable).

Vortex Flow Meter Working Principle for Gas, Steam and Liquid

A vortex flow meter works on the Karman vortex principle, where vortices are generated as the flowing medium passes a specially designed bluff body inside the pipe. The frequency of these vortices is proportional to the flow velocity, allowing the Vortex Flow Sensor to measure the flow of gas, steam or liquid accurately. With its dual vortex sensing and Digital Spectrum Analysis (DSA), the WAFS 1101 supports reliable measurement even in industrial environments where vibration and electromagnetic disturbances may be present.

As a vortex type flow meter, the WAFS 1101 has no moving parts, helping reduce mechanical wear and maintenance requirements. Integrated pressure and temperature measurement can also be used for density compensation and mass-flow calculations. This vortex flow meter working principle makes the instrument suitable for a wide range of industrial utility and process measurement requirements.  Because velocity ranges are given in m/s and flow is often reported in other units, you can convert compressed air flow units when comparing readings with other meters or datasheets.

Applications of WAFS 1101 Vortex Flow Meter

The WAFS 1101 vortex flow meter is suitable for measuring gas, steam and liquid flow in industrial utility and process systems. In Food & Beverage Plants, it can be used for steam distribution, boiler utilities, compressed-air or gas monitoring, and suitable cooling-water or process-liquid applications. The integrated pressure and temperature measurement also supports compensated mass-flow calculations where required.

In Pharmaceutical Plants, the WAFS 1101 can support monitoring of steam, compressed air, gases and suitable industrial liquids used across plant utility and process systems. Its wide measuring range, no-moving-parts design, IP67 protection and optional high-temperature and explosion-proof configurations make it suitable for demanding industrial measurement applications.

Vortex Flow Meter Applications for Steam, Gas and Natural Gas

Vortex flow meter applications include steam distribution, boiler utility monitoring, compressed-air systems, process gases and industrial liquid measurement. A vortex flow meter for steam application can help monitor steam consumption across boilers, production lines and utility networks, while a vortex steam flow meter provides a practical solution for measuring steam flow in demanding industrial environments. The WAFS 1101 is also available with temperature options suitable for different operating conditions.

For gas measurement, the WAFS 1101 can be configured for applications such as compressed air, process gas and natural gas monitoring, subject to application requirements and proper sizing. A vortex flow meter for natural gas can support utility monitoring and energy management, while a vortex gas flow meter can be used across suitable industrial gas systems. These capabilities make vortex technology useful for plants looking for dependable gas and steam measurement. Large compressed-air networks are one such case, and you can see this setting in our guide to compressed air monitoring for cement plants.
