I-flowmeter ye-rotameter iyimitha yokugeleza yendawo eguquguqukayo esebenza ngokusekelwe kumgomo wokulinganisa indawo yokuntanta.
Lapho uketshezi lugeleza ku-flowmeter, ukugeleza koketshezi kuthinta i-rotor futhi kukhiqize amandla kuyo, ubukhulu bayo obuhlukahluka ngesilinganiso sokugeleza.
I-rotor iyakhuphuka noma iwele epayipini elicijile kuze kube yilapho amandla asebenza ku-rotor elingana nesisindo se-rotor. Ngalesi sikhathi,
ubude bendawo ye-rotor bulingana nezinga lokugeleza koketshezi, futhi izinga lokugeleza liboniswa ngenkomba.
