I-Doppler ultrasonic flow metres yakhelwe ukukala ukugeleza kwevolumu yoketshezi oluthwala okuqinile noma olune-aerated ngaphakathi komsele ovaliwe, ulayini wepayipi kufanele ugcwale uketshezi olunamabhamuza omoya athile noma izinto eziqinile ezimisiwe .Lowo ungabonisa izinga lokugeleza kanye nethothameli yokugeleza, njll. .Futhi, icushwe nge-4-20mA , ukuphuma kwe-OCT.Ama-flowmeters aphathwayo afanele usayizi wamapayipi ukusuka ku-40mm-4000mm.Ingasebenza ezindaweni eziningi zokushisa okusebenzayo -20 kuya ku-60 ℃ .Isetshenziswa kabanzi kumapayipi agcwele agcwele , njengamanzi angcolile, udaka olucushiwe, amanzi angaphansi komhlaba, u-pulp, ama-slurries ephepha/amakhemikhali, ukuthuthwa kwamanzi kanye nokujikeleza kabusha kwezimayini nokunye.
