Kodi ndi madzi ati omwe chipangizo choyezera kuthamanga kwa madzi chomwe chimagwiritsidwa ntchito poyezera nthawi yodutsa madzi (transit-time ultrasonic flowmeter) ndi choyenera kuyeza?

Choyezera kuyenda kwa ma ultrasound nthawi yoyenderaimawerengera kuchuluka kwa madzi poyesa kusiyana kwa nthawi pakati pa kufalikira kwa ultrasound mu madziwo ndi kufalikira kwa current current, kenako imapeza kuchuluka kwa madziwo. Madzi oyenera kuyezedwa nthawi zambiri amakhala ndi makhalidwe awa:
Madzi oyera
Madzi akumwa: ubwino wa madzi ndi woyera, wopanda zodetsa, thovu ndi ulusi, sudzasokoneza kwambiri chizindikiro cha ultrasound, ungapangitse mafunde a ultrasound kufalikira bwino, kotero kuti muyeso wa kusiyana kwa nthawi ukhale wolondola, kuti muyese molondola kayendedwe ka madzi, komwe kamagwiritsidwa ntchito kwambiri m'machitidwe operekera madzi m'mizinda, muyeso wa mita yamadzi m'nyumba ndi zochitika zina.
Madzi oyera a mafakitale: monga madzi oyera kwambiri omwe amagwiritsidwa ntchito mumakampani amagetsi ndi makampani opanga mankhwala, kuyera kwake kwakukulu, kutsika kwa mphamvu yamagetsi, kuyamwa pang'ono ndi kufalikira kwa mafunde a ultrasound, choyezera kuyenda kwa madzi a ultrasonic chosiyana ndi nthawi chimatha kuyeza kuyenda kwake molondola kwambiri, zomwe zimathandiza kuwongolera molondola komanso kutsimikizira khalidwe la ntchito popanga.
Madzi otsika kwambiri
Mafuta a petulo, dizilo ndi mafuta ena opepuka: mtundu uwu wa kukhuthala kwa mafuta ndi wotsika, kuyenda bwino, kufalikira kwa ma ultrasound komwe kuchepetsa mphamvu kumakhala kochepa, kutumiza kwa chizindikiro kumakhala kokhazikika, kumatha kuyeza molondola kayendedwe kake mu payipi yamafuta, komwe kumagwiritsidwa ntchito kwambiri m'malo opangira mafuta, muyeso wamafuta a petrochemical ndi maulalo oyendera.
Mankhwala ena osungunuka okhala ndi kukhuthala kochepa: monga ethanol, acetone, ndi zina zotero, nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira kapena zopangira popanga mankhwala. Chifukwa cha kukhuthala kochepa, ndi oyenera kugwiritsa ntchito ma ultrasound flowmeters kuti ayesere kuyenda kwa madzi, zomwe zimakhala zosavuta kugwiritsa ntchito poyang'anira kuchuluka kwa zinthu ndi kayendedwe ka madzi popanga zinthu.
Madzi osawononga kapena owononga pang'ono
Madzi a m'nyanja: ngakhale kuti madzi a m'nyanja ali ndi mchere winawake, koma dzimbiri lake ndi lofooka, pogwiritsa ntchito zipangizo zoyenera zoletsa kuwononga kuti apange ma probe ndi mapaipi oyezera kuyenda kwa madzi, kusiyana kwa nthawi kwa ultrasound flowmeter kungagwiritsidwe ntchito pa zomera zochotsa mchere m'madzi a m'nyanja, kuyang'anira nyanja ndi madera ena oyezera kuyenda kwa madzi a m'nyanja.
Mayankho ena ofooka a asidi, alkali ofooka: monga yankho la citric acid lokhala ndi kuchuluka kochepa, yankho la sodium bicarbonate, ndi zina zotero, m'makampani opanga mankhwala, zakudya ndi zakumwa ndi mafakitale ena, muyeso wa kayendedwe ka mayankho ofooka awa owononga ungagwiritse ntchito flowmeter ya ultrasonic-difference ultrasonic, bola ngati zinthu zoyenera zotsutsana ndi dzimbiri zasankhidwa, zitha kutsimikizira kuti flowmeter ikugwira ntchito bwino komanso kulondola kwa muyeso.
Madzi opanda thovu kapena thovu zingapo zofanana
Mowa ndi zakumwa zina: mu njira yopangira zakumwa, ngakhale pakhoza kukhala thovu laling'ono la mpweya wa carbon dioxide lomwe limapangidwa mu chakumwacho, koma ngati kufalikira kwa thovu kuli kofanana ndipo kuchuluka kwake kuli kochepa, mphamvu ya kufalikira kwa ultrasound imakhala yochepa, kusiyana kwa nthawi ndi ultrasound flowmeter kungakhale muyeso wolondola wa kayendedwe kake, kuti azitha kuwongolera kayendedwe ka zakumwa ndi kuyeza mzere wopanga zakumwa.
Madzi ozungulira okhala ndi mpweya wosungunuka pang'ono: M'mafakitale ena ozungulira madzi, madzi amatha kusungunula mpweya wochepa ndi mpweya wina, koma nthawi zambiri sapanga thovu lalikulu losonkhanitsidwa, ultrasound flowmeter imatha kuyeza bwino kuyenda kwa madzi ozungulira otere, kuti ikwaniritse kuyang'anira ndi kuwongolera makina ozungulira madzi.
