Mukutarisira mvura mumaindasitiri, kudiwa kwezvishandiso zvekuyera zvinosanganisa kururama nekukanganisika kushoma kwemaitiro kwakaita kuti ultrasonic flowmeters ive chinhu chinochinja-chinja. Kusiyana nezvishandiso zvekuyera kuyerera kwechinyakare—zvakaita se turbine metres zvinoda zvikamu zvemukati kuti zvibatane nemvura, kana differential pressure meters izvo zvinogona kuvharika uye kusvibiswa—ultrasonic flowmeters dzinoshanda dzisingapindi mupombi kana kubata mvura pachayo. Dhizaini iyi isingapindi, yakabatana netekinoroji yepamusoro yekugadzirisa masaini, inovabvumira kupa data rakarurama, kugadzirisa matambudziko akakosha mumaindasitiri akasiyana kubva pakuchenesa mvura kusvika kumafuta negesi, uye kugadzira mishonga.
Musimboti mukuru uripo wekushandisa ma ultrasonic flowmeters kuti uverenge kumhanya kwemvura. Mazhinji emaindasitiri anoshandisa matekinoroji maviri akakosha: transit-time uye Doppler effect, imwe neimwe yakagadzirirwa mhando dzemvura asi yakatarisana zvakaenzana nekusapindira. Transit-time ultrasonic flowmeters inoshandisa ma transducer maviri akaiswa kunze pamusoro pepombi, imwe ichitumira uye imwe ichigamuchira ma ultrasound signals. Kana mvura ichiyerera nemupombi, chiratidzo chinofamba munzira yekuyerera (downstream) chinotora nguva shoma kusvika kune chinogamuchira, nepo chiratidzo chichifamba chinopesana nekuyerera (kumusoro) chinotora nguva yakareba. Meter inoverenga musiyano wenguva pakati pemasaini maviri aya, yobva yashandisa data iri—pamwe chete nedhayamita yepombi uye hunhu hwemvura—kuverenga mwero wekuyerera nekunyatsojeka, kazhinji mukati me ±0.5% yehuwandu chaihwo hwemvura yakachena.
Kune mvura dzine zvidimbu zvakasungirirwa kana mabubbles (senge mvura yakasviba, slurry, kana mafuta asina kucheneswa), maDoppler-effect ultrasonic flowmeters ndiwo anonyanya kufarirwa. Midziyo iyi inoburitsa mafungu eruzha ane frequency yakakwira anosvetuka kubva muzvidimbu zviri mumvura; mafungu anoratidzwa anosangana nefrequency shift (inozivikanwa seDoppler effect) zvichibva pakumhanya kwezvikamu, izvo zvinoenderana zvakananga nekumhanya kwemvura. Kunyangwe nezvidimbu izvi, maDoppler metres anochengetedza kurongeka nekubvisa ruzha rwekumashure, zvichiita kuti kuverenga kwemvura kuve kwakavimbika pasina kuda kukanganisa kuyerera kwemvura kana kuisa zvikamu kune zvinhu zvinokuvadza kana zvinoparadza.
Kusapinda kwe ultrasonic flowmeters kunounza mabhenefiti akawanda anoshanda anowedzera kushanda zvakanaka uye kushanda zvakanaka kwemari. Kuisa hakudi kuchekwa kwepombi, kusungirirwa, kana kuvharwa—nyanzvi dzinongobatanidza ma transducers kunze kwepombi, zvichideredza nguva yekushanda kubva pamazuva (kumamita echinyakare) kusvika kumaawa kana kunyange maminetsi. Izvi zvakakosha zvikuru mumaindasitiri akadai sekugadzira magetsi, uko kukanganiswa kwekuyerera kwemvura inotonhorera kunogona kukonzera kudzimwa kunodhura. Pamusoro pezvo, sezvo pasina zvikamu zvemukati, ma ultrasound metres anodzivirira matambudziko akadai sekusakara, kuvharika, kana kusvibiswa kwemvura—matambudziko anotambudza turbine kana positive displacement metres. Semuenzaniso, mukugadzira mishonga, izvi zvinoreva kuti hapana njodzi yekuti simbi kubva kuzvinhu zvakasakara zvipinde mu ultra-pure, zvichiona kuti zvinotevedzera mitemo yakasimba.
Kunyatsojeka kwakanyanya ndeimwe simba guru, rinogoneka nekuda kwekufambira mberi mukugadzirwa kwemasaini edhijitari uye tekinoroji ye sensor. Ma flowmeter emazuva ano e ultrasonic anogona kugadzirisa zvinhu zvakaita se tembiricha, kumanikidzwa, uye zvinhu zvepaipi (semuenzaniso, simbi, PVC, kana mhangura) munguva chaiyo, achigadzirisa kukanganisa kwezviratidzo uye achichengetedza kururama mumamiriro ekushanda anochinja. Semuenzaniso, mumasisitimu ekugovera mvura, anogona kuona kunyangwe kudonha kudiki kana kuchinja kwekuyerera, zvichibatsira masangano emagetsi kuderedza marara emvura uye kugadzirisa mashandiro enetwork. Muindasitiri yemafuta negesi, kugona kwavo kuyera mvura ine viscosity yakawanda nemazvo kunoita kuti pave nekubhadhara kwakarurama kwekufambisa mafuta uye kudzivirira kurasikirwa kwemari kubva mukukanganisa kwekuyera.
Kunze kwekushandiswa kwemaindasitiri, ma ultrasonic flowmeters ari kuwanawo mukana wekushanda munzvimbo dzekugara nedzemabhizimisi—senge ma smart water metres anogonesa kutarisa kushandiswa kwemvura ari kure—nekuda kwekugadzirwa kwawo kudiki uye kusanyanya kugadzirisa zvinodiwa. Sezvo kugara kwenguva refu kuchiva chinhu chinonyanya kukosheswa pasi rose, kugona kwawo kutevera kushandiswa kwemvura nekushandisa simba shoma (mazhinji anoshandisa mabhatiri ane simba shoma) kunowedzera kukwezva kwawo.
Mukupedzisa, ultrasonic flowmeters inotsanangura patsva kuyerwa kwemvura nekubatanidza nyore nyore kusingapindi mvura nemazvo. Nekubvisa zvipingamupinyi zvemidziyo yechinyakare—kubva panguva yekushanda kwekuisa kusvika kunjodzi dzekusvibiswa—hazvingobatsiri chete kushanda zvakanaka asiwo zvinotsigira kutevedzera mitemo, kuchengetedza mari, uye kugara kwenguva refu mumaindasitiri ese. Sezvo tekinoroji ichiramba ichifambira mberi, kururama kwavo uye kushanduka-shanduka kwavo zvichangokura, zvichisimbisa basa ravo sedombo guru remazuva ano rekugadzirisa mvura.
