測(cè)量流體流量的儀表統(tǒng)稱為流量計(jì)或流量表．流量計(jì)是工業(yè)測(cè)量中重要的儀表之一．隨著工業(yè)生產(chǎn)的發(fā)展，對(duì)流量測(cè)量的準(zhǔn)確度和范圍的要求越來(lái)越高，流量測(cè)量技術(shù)日新月異．為了適應(yīng)各種用途，各種類型的流量計(jì)相繼問(wèn)世。目前已投入使用的流量計(jì)已超過(guò)100種。每種產(chǎn)品都有它特定的適用性,也都有它的局限性。按測(cè)量原理分有力學(xué)原理、熱學(xué)原理、聲學(xué)原理、電學(xué)原理、光學(xué)原理、原子物理學(xué)原理等。檢測(cè)件又可按其標(biāo)準(zhǔn)化程度分為二大類:標(biāo)準(zhǔn)的和非標(biāo)準(zhǔn)的。所謂標(biāo)準(zhǔn)檢測(cè)件是只要按照標(biāo)準(zhǔn)文件設(shè)計(jì)、制造、安裝和使用,無(wú)須經(jīng)實(shí)流標(biāo)定即可確定其流量值和估算測(cè)量誤差。非標(biāo)準(zhǔn)檢測(cè)件是成熟程度較差的,尚未列入國(guó)際標(biāo)準(zhǔn)中的檢測(cè)件。
