Ma "Vortex flowmeters" anoshanda pamutemo weKarman Vortex Street.
Muviri we bluff wakagadzika (generator ye vortex) unoiswa pakati pechubhu yekuyera. Kana mvura (mvura, gasi kana utsi) ichiyerera nepachipingamupinyi ichi, kuyerera kwayo kunoparadzaniswa kumativi ese emuviri we bluff. Ma vortex akajairwa, anochinjana acharamba achidonha kubva kumativi maviri panguva yakatarwa, zvichiita mitsara ye vortex inonzi Karman vortex street.
Kuwanda kwekupatsanurwa kwemavortex kune hukama hwakasimba hwakaenzana neavhareji yekumhanya kwemvura mukati mehuwandu hwakati hweReynolds. Kumhanya kwekuyerera kwakakwira, ndiko kuwedzera kwekubuda kwevortex.
Masensa epiezoelectric akavakirwa mukati anoona zviratidzo zvidiki zve pressure pulse zvinogadzirwa kana vortex yega yega yasvika pachinhu chinonzwa. Chinoshandura chinowedzera, chinosefa uye chinogadzirisa zviratidzo izvi zve pulse, chobva chashandura chiratidzo che frequency kuita instantaneous flow rate uye cumulative total flow volume.
Sezvo pasina zvikamu zvemuchina zvinotenderera kana zvinofambiswa mukati memita, matambudziko ekukweshana kwemuchina uye kuvharika kwesimbi anodziviswa, zvichiunza kushanda kwakasimba kwekuyera kwenguva refu.
