Ma ultrasonic flow mita anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana kuyera kuyerera kwezvinwiwa nemagasi. Imwe yema ultrasonic flow mita anowanzo shandiswa ndiyo Doppler flow mita. Rudzi urwu rwe flow mita runoshandisa Doppler effect kuyera kuyerera kwezvinwiwa zvine suspended particles kana air bubbles. Ma Doppler flow mita anonyanya kushanda mukushandiswa uko mvura kana gasi rine tsvina kana solid particles.
Kune mhando dzakawanda dzema ultrasonic flow meters, imwe neimwe ine maficha ayo akasiyana uye mashandisirwo ayo. Kuwedzera kuma Doppler flowmeters, mamwe marudzi ema ultrasonic flowmeters anosanganisira transit flowmeters uye open channel flowmeters.
Mamita ekuyerera kwemvura anowanzo shandiswa mukushandiswa kwemvura yakachena uko mvura isina zvidimbu zvakasungirirwa kana mabubble emhepo. Mamita ekuyerera aya anoshanda nekuyera mutsauko wenguva inotora kuti chiratidzo che ultrasound chifambe kumusoro nekudzika mumvura. Nekuenzanisa nguva dzekufambisa, mwero wekuyerera kwemvura unogona kutsanangurwa nemazvo.
Kumwewo, ma "open channel flowmeters" anoshandiswa kuyera kuyerera kwemvura mumigero yakavhurika yakadai senzizi, hova, uye migero. Ma "flowmeters" aya anoshandisa ma "ultrasonic sensors" kuyera mwero wemvura uye mwero wemvura, zvichibvumira kuverenga kwemvura nemazvo.
Mhando yega yega ye ultrasonic flow meter ine zvayakanakira nezvayakaipira, zvichiita kuti ikwanise kushandiswa zvakasiyana. Doppler flow meter dzakanakira kushandiswa uko mvura kana gasi rine tsvina kana zvidimbu zvakasimba, nepo transit flow meter dzakakodzera kushandiswa kwemvura yakachena. Open channel flowmeters, kune rumwe rutivi, dzakagadzirirwa kuyera kuyerera kwemvura mumigwagwa yakavhurika.
Pamusoro pezvinhu zvinoshandiswa pakushandisa, ma ultrasonic flow meter ane mabhenefiti akawanda pane matekinoroji ekuyera kuyerera kwechinyakare. Haapindi, zvichireva kuti haabatani nemvura inoyerera kana magasi, zvichideredza njodzi yekusvibiswa kana kukuvara kwe flow meter. Ma ultrasonic flow meter anopawo kunyatsojeka uye anogona kuyera kuyerera nekuderera kushoma kwe pressure, zvichiita kuti zvive zvakanaka kune akasiyana mashandisirwo emaindasitiri.
Pamusoro pezvo, ma ultrasonic flow meters ari nyore kuisa nekugadzirisa, zvichitora nguva shoma yekuisa uye kugadzirisa. Anokwanisawo kuyera flow kumativi ese, zvichiita kuti akwanise kushandiswa uko flow direct inogona kuchinja nekufamba kwenguva.
Muchidimbu, mita dzekuyerera dzinoshandisa ultrasonic, kusanganisira Doppler, transit uye open channel flow metres, dzinopa mhinduro dzakasiyana-siyana uye dzakavimbika dzekuyera kuyerera kwemvura negasi mumabasa akasiyana-siyana emaindasitiri. Rudzi rwega rwemita yekuyerera inoshandisa ultrasonic ine maficha ayo akasiyana uye mashandisirwo ayo, saka zvakakosha kusarudza mhando chaiyo yemita yekuyerera zvichienderana nezvinodiwa zvekushandisa. Nekuda kwehunhu hwadzo husina kupindira, kunyatsojeka uye nyore kuisa, mita dzekuyerera dzinoshandisa ultrasonic dzichiri sarudzo yakakurumbira yekuyera kuyerera muindasitiri dzakasiyana-siyana.
