Ma'aunin bututu na Flow Meter ne wani short bututu da ba na magnetic alloy da aka saka a cikin kayan rufi. Biyu lantarkin lantarki a kan ma'auni bututun ta hanyar bututun diameter bango. Its electrode kai ne daidai da ciki surface na liner. Lokacin da magnetic coil stimulated da biyu bangarorin wave pulses, zai samar da aiki magnetic filin da magnetic kwarara yawa B a tsaye shugabanci da ma'auni bututun axis. A wannan lokacin, idan ruwa yana gudana ta hanyar bututun ma'auni tare da wani conductivity. Sensor yankan magnetic line fitar da lantarki karfin E. Electric karfin E daidai da magnetic kwarara yawa B, auna multiplication na bututun ciki diamita d da matsakaicin kwarara gudun V. An gano ƙarfin lantarki E (siginar kwarara) ta hanyar lantarki kuma an aika shi zuwa mai juyawa ta hanyar kebul.
