The vortex flow sensor for high-precision water flow detection covers multiple pipe diameters from DN6 to DN32, with optional wide measurement ranges enabling stable measurement from low to medium-high flow rates. The flow sensor supports multiple output formats including 0–10V, 4–20mA, frequency/pulse, and RS485, facilitating rapid integration into automated systems. With an IP65-rated overall structure, it operates stably over extended periods in environments ranging from −30 to 65 °C, suitable for water and aqueous solution media.

The vortex flow sensor operates based on the von Kármán vortex street principle. Under specific conditions, when a fluid with a constant volumetric flow rate passes around a disturbance column, two rows of vortices with opposite rotational directions and regular arrangement form periodically on both sides of the column. After nonlinear interactions, these vortices form a Kármán vortex street. The formation frequency of these vortices is proportional to the flow velocity. The sensor detects these vortices to measure the flow rate of the fluid within the pipeline.
Specifically designed for the home appliance and medical industries, providing solutions for scenarios such as water heaters, HVAC flow detection, heat recovery systems, and medical liquid flow monitoring systems.
