    RETZ/我們一直致力于流體控制和測(cè)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(cè)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(cè)量,如氣體、液體、蒸汽等多種介質(zhì),也可測(cè)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(cè)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

    進(jìn)口渦街流量計(jì)主要特點(diǎn) Main features

    高強(qiáng)度壓電晶體,一體成形,耐沖擊 High strength piezoelectric crystal, integrated forming, impact resistant

    兼容液體、氣體、導(dǎo)熱油以及蒸汽計(jì)量 Compatible with liquid, gas, thermal oil, and steam metering

    音速噴嘴,重復(fù)性高,測(cè)量精度高 Sonic nozzle calibration with high repeatability and measurement accuracy

    可自由選配溫度補(bǔ)償、壓力溫度,滿足更多現(xiàn)場(chǎng)使用 Free selection of temperature compensation and pressure temperature to meet more on-site use

    電路板出廠前老化運(yùn)行,且整表逐臺(tái),更適合現(xiàn)場(chǎng)使用 The circuit board is aged and operated before leaving the factory, and the entire meter is calibrated one by one, making it more suitable for on-site use

    采用消擾電路和抗振動(dòng)傳感頭,具有良好的抗環(huán)境振動(dòng)性能 Adopting anti-interference circuits and anti vibration sensing heads, it has good anti environmental vibration performance
