　　同步取樣技術性：當信號連續時，可應用同步取樣技術性對信號進行取樣。但特別注意取樣區域

，其qi均jun值zhi為wei零ling，可ke有you效xiao抑yi製zhi幹gan撓nao的de影ying響xiang。

　　數字濾波技術性：該技術性是智能儀表中較為常見的一種技術性，能有效的完成模擬過濾裝置不能完成的功能。很容易解決脈衝幹撓，數字電路幹撓、S/D轉換器高頻幹撓等。

　　1
、首先確認管道中是否填滿流體；

　　2、如果管道太靠近牆麵
，可在有傾斜角度的管道直徑上安裝探頭
，而不必非在水平管道直徑上安裝，應選用Z法安裝探頭；

　　3
、仔細選擇管道致密部分並充分打磨明亮，塗抹充分的藕合劑安裝好探頭
；

　　4、分(fen)別(bie)細(xi)心(xin)地(di)在(zai)電(dian)磁(ci)流(liu)量(liang)計(ji)的(de)安(an)裝(裝)點(dian)附(fu)近(jin)慢(man)慢(man)移(yi)動(dong)每(mei)個(ge)探(tan)頭(tou)，尋(xun)找(zhao)到(dao)最(zui)大(da)信(xin)號(hao)點(dian)
