多孔流量計的特點(多孔平衡流量計)
▲線(xian)(xian)性(xing)度(du)高、重(zhong)復性(xing)好、精(jing)度(du)高:多(duo)孔流量傳感(gan)器具有(you)對稱多(duo)孔結(jie)構特(te)點,能對流場進行多(duo)孔,降低了(le)渦(wo)流、振動和信(xin)號噪(zao)聲,流場穩定性(xing)大大提(ti)高,使線(xian)(xian)性(xing)度(du)比(bi)孔板提(ti)升了(le)5~10倍,重(zhong)復性(xing)提(ti)高了(le)54%,為(wei)0.15%,精(jing)度(du)達0.5級。從其綜合性(xing)能來看(kan),多(duo)孔流量計屬于高檔(dang)流量計行列。5:1量程比(bi)時,線(xian)(xian)性(xing)度(du)可(ke)達±0.3%;7:1量程比(bi)時,線(xian)(xian)性(xing)度(du)可(ke)達±0.5%;10:1量程比(bi)時,線(xian)(xian)性(xing)度(du)可(ke)達±1.0%。▲ 直管段要求(qiu)低:多(duo)...
