在業(yè)務(wù)方面，水氣表上報數(shù)據(jù)多上報一次，有的甚至一個月上報一次，因此NB-IoT的工作模式非常適合這種業(yè)務(wù)模式。當(dāng)前水氣表比較常用的計數(shù)方式有干簧管脈沖計數(shù)和光電直讀計數(shù)，NB-IoT更適用于光電直讀計數(shù)。在采用光電直讀計數(shù)方式的燃?xì)獗碇衂M7100系列模組在PSM模式下功耗可達(dá)2uA，2400mAh的電池在信號覆蓋比較好的區(qū)域下，續(xù)航時間可達(dá)25年，在信號強(qiáng)度弱的情況下，發(fā)射功率4次重發(fā)，電池可續(xù)航達(dá)到15年。通常水氣表的壽命要達(dá)到10年左右，因此ZM7100系列模組能充分滿足當(dāng)前水氣表的功耗要求。
