西門子電磁流量計，7ME流量傳感器系列 妍溪優(yōu)勢代理

zui適宜的流量計

為特定的應(yīng)用而使用zui適宜的流量計能顯著地提升生產(chǎn)率。這就是為什么西門子提供廣泛的電磁、科里奧利、超聲波、渦街、旋轉(zhuǎn)活塞和差壓流量計的選擇。不過您所有應(yīng)用的是什么工業(yè)，我們都能給您提供理想的流量計。

電磁流量計是為供水企業(yè)水計量貿(mào)易專門設(shè)計的，具有防水、防腐、防干擾、防雷擊的能力。

電磁流量計特別設(shè)計了帶背光寬溫的中文液晶顯示器，功能齊全實用、顯示直觀、操作使用方便，可以減少其他電磁流量計英文菜單所帶來的不便。另外我們*設(shè)計4-6多電極結(jié)構(gòu)，進一步保證了測量精度并且任何時候無需接地環(huán)，減輕了儀表體積和安裝維護的麻煩。  

電磁流量計

電磁流量計在滿足現(xiàn)場顯示的同時，還可以輸出4～20mA電流信號供記錄、調(diào)節(jié)和控制用，現(xiàn)已廣泛地應(yīng)用于化工、環(huán)保、冶金、醫(yī)藥、造紙、給排水[1]等工業(yè)技術(shù)和管理部門。 采用電磁感應(yīng)原理測量介質(zhì)流體流速的電磁流量計。它在管道的兩側(cè)加一個磁場，被測介質(zhì)流過管道就切割磁力線，在兩個檢測電極上產(chǎn)生感應(yīng)電勢，其大小正比于流體的運動速度。可以用于測量酸、堿、鹽溶液、水煤漿、礦漿、砂漿灰泥、紙漿、樹脂、橡膠乳、合成纖維漿和感光乳膠等各種懸浮物、氣化汽和粘性物質(zhì)的流量。電磁流量計密封性能好，還可用于自來水和地下水道系統(tǒng)。而且測量過程不與流體接觸，適于制藥、生物化學(xué)和食品工業(yè)。這種流量計還可檢測血液流量。它的量程比約為100:1，精度一般為1％，由于這種傳感器必須保持管道內(nèi)電阻和測量電路阻抗之間有一定比例關(guān)系，因此在制造上有一定困難。當(dāng)被測介質(zhì)的電導(dǎo)率約為10歐姆·厘米時就開始產(chǎn)生困難，電導(dǎo)率更低時就產(chǎn)生原理性困難。當(dāng)電導(dǎo)率為10歐姆·厘米時，就達到導(dǎo)電介質(zhì)和電介質(zhì)之間的“分界線”，熱噪聲電平隨內(nèi)阻的增大而顯著增加。

  電磁流量計是高精度、高可靠和使用壽命長的流量儀表，所以在設(shè)計產(chǎn)品結(jié)構(gòu)、選材、制定工藝、生產(chǎn)裝配和出廠測試等過程中每一個環(huán)節(jié)我們都非常細致講究，還自行設(shè)計了一套中國的，于電磁流量計的生產(chǎn)設(shè)備和流量實流標(biāo)定裝置，從而在軟件和硬件上都能切實保證產(chǎn)品*的高質(zhì)量。電磁流量計特別設(shè)計了帶背光寬溫的中文液晶顯示器，功能齊全實用、顯示直觀、操作使用方便，可以減少其他電磁流量計英文菜單所帶來的不便。另外我們*設(shè)計4-6多電極結(jié)構(gòu)，進一步保證了測量精度并且任何時候無需接地環(huán)，減輕了儀表體積和安裝維護的麻煩
