Clamping vortex flow meters come in the form of pipeline and plug-in flow sensors, without movable components, stable and reliable, with flexible and convenient installation methods. According to the on-site process pipeline, they can be installed horizontally, vertically, and at different angles with inclination

進口夾持式渦街流量計原理及用途Principle and purpose

渦街流量計是根據卡門(Karman)渦街原理研究生產的測量氣體、蒸汽或液體的體積流量、標況的體積流量或質量流量的體積流量計。主要用于工業管道介質流體的流量測量，如氣體、液體、蒸汽等多種介質，也可測量含有微小顆粒、雜質的渾濁液體，廣泛應用于石油、化工、制藥、造紙、冶金、電力、環保、食品等行業。

Vortex flow meter is a volume flow meter that measures the volume flow rate, standard volume flow rate, or mass flow rate of gas, steam, or liquid based on the Karman vortex flow principle. Mainly used for flow measurement of industrial pipeline medium fluids, such as gases, liquids, steam, and other media. It can also measure turbid liquids containing small particles and impurities, and is widely used in industries such as petroleum, chemical, pharmaceutical, papermaking, metallurgy, power, environmental protection, and food.

傳感器輸出為脈沖頻率，其頻率與被測流體的實際流量呈線性，零點無漂移，性能穩定，結構形式多樣 The output of the sensor is a pulse frequency, which is linear with the actual flow rate of the measured fluid, with zero drift, stable performance, and diverse structural forms
