Ma ultrasonic flow meter anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana kuyera kuyerera kwemvura negasi. Anozivikanwa nekururama kwawo, kuvimbika, uye kusapinda, zvichiita kuti ave sarudzo yakakurumbira kune akawanda mashandisirwo. Kune mhando mbiri huru dze ultrasonic flowmeter technology: transit-time method uye Doppler method. Mublog rino, tichaongorora musiyano uripo pakati pematekinoroji maviri aya nemashandisirwo awo.
Nheyo inoshanda ye ultrasonic flow meter yenguva yekufamba ndeyekuyera nguva inotora kuti chiratidzo che ultrasonic chipararire kumusoro nekudzika kwemvura mupaipi. Musiyano wenguva yekufamba unoenderana nehuwandu hwekuyerera kwemvura. Iyi tekinoroji yakakodzera mvura yakachena, yakafanana ine zvidimbu zvishoma kana mabubble emhepo. Inowanzoshandiswa mukushandiswa kwakadai sekutarisira mvura nemvura yakasviba, masisitimu eHVAC, uye maitiro emaindasitiri uko mvura yacho isina tsvina.
Kumwewo, maDoppler ultrasonic flow mita anoshandisa Doppler effect kuyera flow rate yemvura. Tekinoroji iyi inoshanda nekubudisa ma ultrasound signals anoonekwa nezvidimbu kana mabubbles ari mumvura. Kuchinja kwefrequency ye reflection signal kunoshandiswa kuverenga flow rate. MaDoppler flowmeters akakodzera mvura dzine suspended particles kana air bubbles, zvichiita kuti ive sarudzo yekutanga yekushandisa slurry, wastewater ine solids uye air liquids.
Imwe yemisiyano mikuru pakati pemamita ekuyerera kwemvura eultrasonic anofambiswa nenguva yekufamba uye mamita ekuyerera kwemvura eDoppler anoshandiswa zvakanyanya ndekuti akakodzera mhando dzakasiyana dzemvura. Kunyange zvazvo mamita ekuyerera achishanda zvakanaka mumvura dzakachena, dzakafanana, mamita eDoppler akakodzera kubata mvura dzine tsvina kana kuti dzine mhepo. Pakusarudza tekinoroji yakakodzera yemuchina wekuyera mvura yeultrasonic yekushandisa, zvakakosha kufunga nezvehunhu hwemvura iri kuyerwa.
Chimwe chinhu chekufunga nezvacho ihukuru hwepombi nezvinhu. Ma flow meter e ultrasonic anofambiswa panguva yekufamba akakodzera saizi dzakasiyana dzepombi nezvinhu, kusanganisira simbi, mapurasitiki nekongiri. Anowanikwa kumapombi madiki neakuru, zvichiita kuti akwanise kuiswa zvakasiyana-siyana. Ma Doppler flowmeters, kune rumwe rutivi, anogona kunge aine miganho muhukuru hwepombi uye kuenderana kwezvinhu nekuti kuvapo kwezvidimbu kana mabubble emhepo mumvura kwakakosha pakushanda kwawo.
Pamusoro pehunhu hwemvura uye kufunga nezve pombi, kuiswa uye kugadziriswa kwe ultrasonic flow meter kunofanirawo kufungwa nezvako. Kunyange zvazvo transit meter ichiwanzoda mapombi akatwasuka kuti iite zviyero zvakarurama, Doppler meter inogona kunge yakasununguka zvakanyanya maererano nezvinodiwa pakuiswa nekuda kwekugona kwayo kushanda paine zvidimbu kana mabubbles.
Muchidimbu, kunzwisisa marudzi ese ari maviri e ultrasonic flow meter tekinoroji (nguva yekuchinja uye Doppler) kwakakosha pakusarudza mhinduro chaiyo yekushandisa chaiyo. Nekufunga nezvemhando yemvura, saizi yepombi nezvinhu, uye zvinodiwa pakuisa nekugadzirisa, vashandisi vanogona kuita sarudzo dzakadzidziswa kuti vave nechokwadi chekuti kuyerwa kwemvura kwakarurama uye kwakavimbika. Kungave kutarisa kuyerera kwemvura musystem yemuguta kana kuyera kuyerera kweslurry muindasitiri, sarudzo pakati pe transit time ultrasonic flow meters uye Doppler ultrasonic flow meters inogona kuve nemhedzisiro yakakura pakushanda kwemhinduro yekuyera.
