Li-flowmeter tsa vortex li sebetsa ho latela molao-motheo oa Seterata sa Karman Vortex.
'Mele o tsitsitseng oa bluff (jenereithara ea vortex) o kentsoe bohareng ba tube ea ho lekanya. Ha mokelikeli (mokelikeli, khase kapa mouoane) o phalla ka har'a tšitiso ena, phallo e aroloa mahlakoreng ka bobeli a 'mele o boreleli. Li-vortex tse tloaelehileng, tse fapanyetsanang li tla tsoela pele ho tsoa mahlakoreng a mabeli ka maqhubu a tsitsitseng, li etsa letoto la mela ea li-vortex e bitsoang seterata sa Karman vortex.
Maqhubu a karohano ea vortex a na le kamano e tiileng e lekanang le lebelo le tloaelehileng la phallo ea mokelikeli ka har'a mefuta e itseng ea linomoro tsa Reynolds. Ha lebelo la phallo le phahame, maqhubu a ho lahla vortex a phahame.
Li-sensor tsa piezoelectric tse hahiloeng kahare li lemoha matšoao a manyane a khatello a hlahisoang ha vortex e 'ngoe le e 'ngoe e otla karolo ea kutlo. Sefetoleli se eketsa, se sefa le ho sebetsana le matšoao ana a pulse, ebe se fetola lets'oao la maqhubu hore e be sekhahla sa phallo ea hang-hang le bophahamo ba phallo e kopaneng.
Kaha ha ho na likarolo tsa mechini tse potolohang kapa tse ka tsamaisoang ka hare ho mithara, mathata a ho hohlana le ho thibana ha mechini aa qojoa, e leng se tlisang ts'ebetso e tsitsitseng ea tekanyo ea nako e telele.
