電磁流量計(jì)內(nèi)的測量電極處于一個(gè)直流或交流電場內(nèi)，如果其環(huán)境不能有效地被屏蔽于一個(gè)無干擾的條件下，對(duì)測量有嚴(yán)重干擾。傳感器外殼接地與否，直接關(guān)系到測量的精度和穩(wěn)定性，接地導(dǎo)線必須不傳任何干擾電壓，因此電磁流量計(jì)要求有非常可靠的接地，要做好接地屏蔽，否則就會(huì)產(chǎn)生干擾電流。<span style="font-size:12px;"> </span> </p> <p> 電磁流量計(jì)接地的好處： </p> <p> 若連接流量計(jì)的管道是(相對(duì)于被測介質(zhì))絕緣的則要用接地環(huán)，它的材質(zhì)應(yīng)根據(jù)被測介質(zhì)的腐蝕性選用。如果是聚四氟乙烯內(nèi)襯的測量傳感器，為了保測量傳感器能正常工作，要選用接地環(huán)。 </p> <p> 超聲波流量計(jì)
