3．環(huán)保工程
人口劇增，工業(yè)生產(chǎn)迅猛發(fā)展使得環(huán)境嚴(yán)重惡化，已經(jīng)達(dá)到危險(xiǎn)的程度，國(guó)家把可持續(xù)發(fā)展列為國(guó)策，它將是二十一世紀(jì)的大課題。空氣污染、水污染要得到控制必須加強(qiáng)管理，而管理的基礎(chǔ)是污染量的定量控制。我國(guó)是以煤為主要能源的國(guó)家，全國(guó)有上百萬(wàn)的煙囪日夜不停地向大氣排放濃煙，煙氣排放控制成為根治污染的重要項(xiàng)目。美國(guó)已經(jīng)立法規(guī)定煙廢氣排放標(biāo)準(zhǔn)，每個(gè)煙囪必須安裝煙氣分析儀和流量計(jì)，組成連續(xù)排放監(jiān)視系統(tǒng)（CEMS）。煙廢氣流量測(cè)量屬于困難的測(cè)量問(wèn)題，它的難度有：
