Cov keeb kwm ntawm flowmeter tuaj yeem taug qab rov qab mus rau theem pib yam ntxwv los ntawm kev ntsuas yooj yim, empirical. Nyob rau lub sijhawm ntawd, tib neeg feem ntau tso siab rau cov qauv xws li cov kav dej thiab cov phaj hauv qhov ncauj kom kwv yees tus nqi ntws los ntawm kev soj ntsuam seb cov kua dej hloov pauv li cas hauv cov qauv ruaj khov no. Txawm hais tias cov txheej txheem yooj yim, cov txheej txheem no muaj qhov tseeb tsawg thiab tau siv feem ntau hauv cov haujlwm engineering xws li kev siv dej thiab kev txuag dej.
Nrog lub advent ntawm industrialization, mechanical flow meters maj mam tau txais kev pom zoo; Cov khoom siv xws li turbine flow meter, oval gear flow meter, thiab rotameters tau pib siv rau hauv cov roj av, tshuaj, thiab dej ua haujlwm. Flow meters los ntawm lub sijhawm no tau pom qhov ntsuas qhov tseeb thiab ruaj khov, ua tau raws li qhov yuav tsum tau muaj rau kev ntsuas thiab kev tswj cov txheej txheem hauv kev tsim khoom, yog li tsav kev nce qib ntawm cov txheej txheem kev lag luam.
Tsav los ntawm kev nce qib hauv electronics thiab computer technology, flow meters tau nkag mus rau niaj hnub, ntse era. Ib qho kev txuas ntxiv ntawm cov khoom lag luam tshiab-xws li electromagnetic, ultrasonic, thiab Coriolis huab hwm coj ntsuas ntsuas- tau tshwm sim, ua kom muaj peev xwm xws li tsis yog- ntsuas kev sib cuag, siab - nyeem ntawv ceev, thiab cov ntaub ntawv tso tawm digital. Tsis tas li ntawd, los ntawm kev koom ua ke nrog automation systems thiab Internet of Things (IoT) platforms, flow meters tau hloov zuj zus tshaj li cov cuab yeej ntsuas los pab tswj cov chaw taws teeb, cov ntaub ntawv txheeb xyuas, thiab kev tswj xyuas ntse, yog li dhau los ua ib qho tseem ceeb ntawm kev lag luam automation niaj hnub no.
