：RETZ/我們一直致力于流體控制和測控領(lǐng)域的持續(xù)創(chuàng)新，始于2005……進(jìn)口渦街流量計(jì)原理及用途Principle and purpose

渦街流量計(jì)是根據(jù)卡門(Karman)渦街原理研究生產(chǎn)的測量氣體、蒸汽或液體的體積流量、標(biāo)況的體積流量或質(zhì)量流量的體積流量計(jì)。主要用于工業(yè)管道介質(zhì)流體的流量測量，如氣體、液體、蒸汽等多種介質(zhì)，也可測量含有微小顆粒、雜質(zhì)的渾濁液體，廣泛應(yīng)用于石油、化工、制藥、造紙、冶金、電力、環(huán)保、食品等行業(yè)。

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 d 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, ermaking, llurgy, 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(shí)際流量呈線性，零點(diǎn)無漂移，性能穩(wěn)定，結(jié)構(gòu)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
