Nekuda kwekusapindira kwavo uye nyore kuisa, ma clamp-on ultrasonic flow meters ave sarudzo yakakurumbira yekuyera kuyerera kwemvura mumaindasitiri akasiyana-siyana. Zvisinei, chimwe chinhu chakakosha chinowanzo furatirwa inodiwa ye straight pipe yeaya flow metres. Mublog rino, tichaongorora kukosha kwe straight pipe re clamp-on ultrasonic flow metres uye kuti nei zvichikosha pakuyera kuyerera kwemvura nemazvo uye zvakavimbika.
Zvinodiwa papombi dzakatwasuka zvinoreva kureba kwepombi dzakatwasuka dzinofanira kuvapo kumusoro nekuzasi kwemugero wemvura kuti zvive nechokwadi chekuti mafambiro emvura akarurama uye kuyerwa kwakarurama. Kune mafambiro emvura e ultrasonic anosungirirwa, kuvapo kwepombi dzakatwasuka kwakakosha kuti zviratidzo zve ultrasound zvitumirwe zvakanaka uye zvigamuchirwe.
Mutemo mukuru wezvinodiwa zvepombi yakatwasuka ndewekuti panofanira kunge paine dhayamita gumi dzepombi yakatwasuka kumusoro kwemugero wemvura uye dhayamita shanu dzepombi yakatwasuka pasi. Izvi zvinoreva kuti kana dhayamita yepombi iri 4 inches, panofanira kunge paine dhayamita makumi mana epombi yakatwasuka kumusoro kwemugero wemvura uye dhayamita makumi maviri epombi yakatwasuka pasi.
Chikonzero chezvinodiwa izvi chiri mumhando yekuyerera kwemvura. Kana mvura ichipinda mu flow meter, inogona kunge iine ma vortices, turbulence, kana equal velocity distribution. Kuvapo kwemapombi akatwasuka kunoita kuti kuyerera kwemvura kugadzikane uye kunoita kuti kupararira kwemhepo kuenderane, izvo zvakakosha pakuyera kwe ultrasound nemazvo.
Pasina kureba kwakakodzera kwepombi yakatwasuka, chiratidzo che ultrasound chinogona kukanganiswa uye kuratidzwa nema profiles ekuyerera asina kuenzana, zvichikonzera kuyerwa kwekuyerera kusina kururama. Izvi zvinogona kutungamira kudata risingavimbike, zvichikonzera zvikanganiso zvinogona kuitika mukudzora maitiro nekutarisa.
Pamusoro pekureba kwepombi yakatwasuka, mamiriro epombi akakoshawo. Chero zvipingamupinyi zvakaita semavharuvhu, magokora, kana shanduko mudhayamita yepombi zvinogona kukanganisa mafambiro emvura uye kukanganisa kururama kwekuyera. Zvakakosha kuve nechokwadi chekuti kureba kwakatwasuka kwepombi hakuna zvipingamupinyi zvakadaro kuti mafambiro emvura arambe akasimba.
Zvakakoshawo kuziva kuti zvinodiwa pakumhanya zvakananga zvinogona kusiyana zvichienderana nerudzi rwemuchina we clamp-on ultrasonic flow meter uye modhi yawo. Mamwe ma flow meter epamusoro anogona kunge asina zvinodiwa zvakanyanya zvemapombi akatwasuka sezvo achikwanisa kutsiva ma flow profiles asina kuenzana, asi zvakanaka kugara uchitevera zvinokurudzirwa nemugadziri kuti uite zvakanaka.
Mukupfupisa, zvinodiwa zvechikamu chepombi yakatwasuka ye clamp-on ultrasonic flowmeter chinhu chakakosha chinokanganisa zvakananga kururama uye kuvimbika kwekuyera kuyerera. Nekuona kuti hurefu hwakakwana hwepombi yakatwasuka huripo uye kuchengetedza flow profile yakafanana, vashandisi vanogona kuwedzera mashandiro e flowmeter yavo uye kuwana data rakarurama rekushandisa kwavo. Kutevedzera zvinodiwa zvepombi yakatwasuka kwakakosha kuti pave nekugona kwakazara kwe clamp-on ultrasonic flow metres uye kuona mabhenefiti ayo mumabasa akasiyana-siyana emaindasitiri.
