These sensors use the principle that the frequency of Karman vortex shedding generated by fluid flow is proportional to velocity. With excellent stability and a wide temperature operating range, they have become standard configurations for compressed-air cost accounting in industrial plants, saturated steam measurement in boilers, and energy metering in district heating networks.
The SensorsX SX-FVNB Series Vortex Flowmeter is designed for measuring the flow of steam, gases, and liquids using the Kármán vortex principle. It offers reliable accuracy, a wide DN15–DN300 size range, and multiple output options including pulse, 4–20 mA, and RS485. It is suitable for applications such as steam systems, compressed air, oil & gas, chemical processing, and water treatment.
The SensorsX SX-FVMB Series is a compact vortex flow sensor designed for measuring non-corrosive water-based liquids. It simultaneously measures flow rate and temperature, with fast response, ±2% accuracy, and multiple output options including RS485, 4–20 mA, 0–5 V, and IO-Link. Its compact design and rotatable LCD make it suitable for industrial applications such as cooling systems, HVAC, semiconductor manufacturing, and factory automation.
