Iimitha zokuqukuqela zinoluhlu olubanzi lwezicelo kushishino oluzenzekelayo, kumlinganiselo wemithombo yeendaba eyahlukeneyo njengamanzi, ioyile, kunye negesi.Namhlanje, ndiza kwazisa ngembali yophuhliso lweemitha zokuhamba.
Ngomnyaka we-1738, uDaniel Bernoulli wasebenzisa indlela yoxinzelelo oluhlukeneyo ukulinganisa ukuhamba kwamanzi ngokusekelwe kwi-equation yokuqala yeBernoulli.
Kwi-1791, i-GB Venturi yase-Italian yafunda ukusetyenziswa kweetyhubhu ze-venturi ukulinganisa ukuhamba kwaye yapapasha iziphumo.
Ngo-1886, i-American Herschel yasebenzisa ulawulo lwe-Venturi ukuze ibe sisixhobo sokulinganisa esisebenzayo sokulinganisa ukuhamba kwamanzi.
Ngeminyaka yoo-1930, kwavela indlela yokusebenzisa amaza esandi ukulinganisa isantya sokuhamba kolwelo neegesi.
Ngo-1955, i-flowmeter ye-Maxon esebenzisa indlela yokujikeleza kwe-acoustic yaziswa ukulinganisa ukuhamba kwamafutha e-aviation.
Emva kweminyaka yee-1960, izixhobo zokulinganisa zaqala ukuphuhlisa kwicala lokuchaneka kunye ne-miniaturization.
Ukuza kuthi ga ngoku, ngophuhliso lwethekhnoloji yesekethe edibeneyo kunye nokusetyenziswa okubanzi kwee-microcomputers, ukukwazi ukulinganisa ukuhamba kuye kwaphuculwa ngakumbi.
Ngoku kukho i-electromagnetic flowmeters, ii-flowmeters ze-turbine, ii-vortex flowmeters, ii-flowmeters ze-ultrasonic, ii-rotor flowmeters zentsimbi, ii-orifice flowmeters.
