Vortex Shedding Flow Meter

Traditional industrial flow measuring instruments have obvious scenario limitations in multi-medium and high-temperature working conditions. Turbine and rotor flow meters rely on movable mechanical structures, prone to abrasion, stuck rotation and aging failure after long-term operation, requiring frequent maintenance and calibration. Electromagnetic flow meters are only applicable to conductive liquids and cannot measure steam, gas and non-conductive fluids. Ultrasonic flow meters are easily affected by pipeline vibration, medium bubbles and temperature changes, resulting in poor stability and low repeatability. Differential pressure flow devices cause inevitable pipeline pressure loss and are not suitable for high-precision low-flow monitoring. The Vortex Shedding Flow Meter thoroughly solves the above industry pain points. Adopting classic Von Kármán vortex shedding physical principle, a precision delta-shaped bluff body is installed inside the pipeline. When fluid flows through the shedder bar, regular alternating vortices are generated on both sides, and the vortex shedding frequency is linearly proportional to the fluid flow velocity. High-sensitivity piezoelectric sensing unit accurately captures tiny pressure fluctuation signals, and the intelligent digital processing system converts frequency signals into standard volumetric flow data. With no movable mechanical components inside the whole machine, it completely eliminates mechanical wear and fatigue failure. It breaks through medium restrictions, realizing unified measurement of gas, liquid and steam. Industrial high-temperature and high-pressure resistant structure adapts to harsh process conditions, while optimized signal filtering and anti-interference technology ensure stable output in complex industrial environments, becoming a versatile and low-maintenance core flow measuring device for modern industrial automation.

This industrial vortex shedding flow meter supports diversified personalized customization for petrochemical, thermal power, heating engineering, gas transmission and industrial fluid process monitoring projects. Universal three-medium measurement capability covers liquid, gas and saturated/superheated steam, replacing multiple single-function flow meters and saving procurement costs. Non-movable part structural design achieves wear-free operation, effectively reducing later maintenance and replacement frequency. Ultra-wide turndown ratio adapts to fluctuating flow working conditions with both high-flow and micro-flow detection capabilities. High-temperature and high-pressure resistant industrial design stably operates in high-temperature steam and high-pressure pipeline environments. Built-in digital filtering and vibration suppression algorithm eliminates pipeline vibration and electromagnetic interference, ensuring accurate and repeatable data. Integrated intelligent temperature and pressure compensation module automatically corrects steam and gas density deviation, improving actual measurement precision. According to project demands, we can customize pipeline diameter, high-temperature resistant grade, pressure bearing grade, on-site display function, signal output mode and explosion-proof specification to meet refined flow monitoring requirements of different industrial working conditions.
