    FAQ

    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.

    • Minimal sensitivity to ambient temperature with a wide operating temperature range.
    • Low pressure loss and high measurement accuracy.
    • Long service life, contamination resistance, and drift-free operation.
