Limithara tse phallang li na le lits'ebetso tse fapaneng indastering ea li-automation, bakeng sa ho lekanya mecha ea litaba e fapaneng joalo ka metsi, oli le khase.Kajeno, ke tla hlahisa nalane ea nts'etsopele ea li-flow metres.
Ka 1738, Daniel Bernoulli o ile a sebelisa mokhoa o fapaneng oa khatello ho lekanya phallo ea metsi ho latela equation ea pele ea Bernoulli.
Ka 1791, Setaliana GB Venturi o ile a ithuta tšebeliso ea li-tubes tsa venturi ho lekanya phallo le ho hatisa liphetho.
Ka 1886, American Herschel e ile ea sebelisa taolo ea Venturi ho ba sesebelisoa se sebetsang sa ho metha ho lekanya phallo ea metsi.
Lilemong tsa bo-1930, ho ile ha hlaha mokhoa oa ho sebelisa maqhubu a molumo ho lekanya lebelo la ho phalla ha metsi le likhase.
Ka 1955, ho ile ha hlahisoa "flowmeter" ea Maxon e sebelisang mokhoa oa potoloho ea acoustic ho lekanya phallo ea mafura a sefofane.
Ka mor'a lilemo tsa bo-1960, lisebelisoa tsa ho lekanya li ile tsa qala ho ntshetsa pele ho ea ka mokhoa o nepahetseng le oa miniaturization.
Ho fihlela joale, ka nts'etsopele ea theknoloji e kopanetsoeng ea potoloho le ts'ebeliso e pharaletseng ea li-microcomputers, bokhoni ba ho lekanya phallo bo ntlafalitsoe le ho feta.
Hona joale ho na le li-flowmeters tsa motlakase, li-flowmeters tsa turbine, li-vortex flowmeters, li-flowmeters tsa ultrasonic, li-rotor flowmeters tsa tšepe, li-orifice flowmeters.
