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(shí)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(jìn)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(hù)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(yùn)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(dá)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(xì)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(shí)流標(biāo)定裝置，從而在軟件和硬件上都能切實(shí)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(shí)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(jìn)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(hù)的麻煩
