Vortex flowmeter e ka lekanya phallo ea khase, mokelikeli le mouoane, joalo ka phallo ea molumo, phallo ea boima, phallo ea molumo, joalo-joalo Phello ea tekanyo e ntle le ho nepahala ho holimo.Ke mofuta o sebelisoang haholo oa ho metha mokelikeli liphaepheng tsa indasteri 'me o na le liphetho tse ntle tsa tekanyo.
Lethathamo la tekanyo ea phallo ea vortex e kholo, 'me tšusumetso ea tekanyo e nyenyane.Ka mohlala, sekhahla sa mokelikeli, khatello, viscosity, joalo-joalo e ke ke ea ama mosebetsi oa ho lekanya oa vortex flowmeter, kahoo ho khoneha ho ntse ho le matla haholo.
Molemo oa vortex flowmeter ke tekanyo ea eona e kholo ea ho lekanya.Ho tšepahala ho phahameng, ha ho na tlhokomelo ea mechine, hobane ha ho na likarolo tsa mechine.Ka tsela ena, le haeba nako ea ho lekanya e le telele, litekanyetso tsa pontšo li ka ba tse tsitsitseng.Ka sensor ea khatello, e ka sebetsa ka mocheso o tlase le tikolohong ea mocheso o phahameng ka ho ikamahanya le maemo ho matla.Har'a lisebelisoa tse tšoanang tsa ho lekanya, vortex flowmeter ke khetho e nepahetseng.Hona joale, lifeme tse ngata li sebelisa sesebelisoa sa mofuta ona ho lekanya boleng hamolemo le ka nepo.
