Magulu a Masensa mu Doppler Ultrasonic Flow Meters

Mayendedwe - Zosewerera Nthawi

Ma sensor a nthawi yodutsa - amagwira ntchito potengera mfundo yoyezera kusiyana kwa nthawi kuti mafunde a ultrasound ayende motsatira njira yoyendera komanso motsutsana ndi njira yoyendera. Ma sensor amenewa nthawi zambiri amakhala ndi ma transducer awiri a ultrasound. Transducer imodzi imagwira ntchito ngati chotumizira, kutulutsa mafunde a ultrasound mumadzimadzi, pomwe inayo imagwira ntchito ngati cholandirira.

Madzi akamayenda, mafunde a ultrasound omwe akuyenda pansi pa mtsinje adzafika pa wolandila munthawi yochepa poyerekeza ndi omwe akuyenda pamwamba pa mtsinje. Poyesa molondola kusiyana kwa nthawi imeneyi, liwiro la madzi likhoza kuwerengedwa. Zosewerera nthawi zoyendera zimakhala zolondola kwambiri ndipo ndizoyenera kuyeza kuyenda kwa madzi oyera komanso ofanana. Nthawi zambiri zimagwiritsidwa ntchito poyesa kuyenda bwino kwambiri, monga m'mafakitale opangira mankhwala poyesa kuyenda kwa madzi oyera kapena m'malo ena oyeretsera madzi.

Zotsatira za Doppler- Zosensa Zochokera

Doppler effect - masensa ozikidwa pa Doppler effect amadalira Doppler effect, yomwe imachitika pamene pali kuyenda pakati pa gwero la ultrasound (chotumizira), madzi, ndi cholandirira. Mu Doppler ultrasonic flow meter, ultrasonic transducer imatulutsa mafunde a ultrasound mu madzi. Ngati pali tinthu tating'onoting'ono kapena thovu mu madzi, mafunde a ultrasound adzafalikira ndi zinthu zoyendazi. Mafupipafupi a mafunde omwazikana omwe amalandiridwa ndi transducer adzakhala osiyana ndi mafupipafupi omwe amatulutsidwa.

Kusintha kwa ma frequency kumeneku kumagwirizana ndi liwiro la tinthu tating'onoting'ono kapena thovu mumadzimadzi, motero, liwiro la kuyenda kwa madzi lingathe kudziwika. Masensa otengera Doppler effect ndi othandiza kwambiri poyesa kuyenda kwa madzi omwe ali ndi tinthu tating'onoting'ono kapena thovu lopachikidwa, monga madzi a zimbudzi m'malo oyeretsera madzi a zinyalala, matope a mafakitale a pulp ndi mapepala, kapena osakaniza mafuta mumakampani opanga mafuta.

Kuwonjezera pa mitundu iwiri ikuluikulu iyi, palinso masensa ena osakanikirana omwe amaphatikiza mawonekedwe a transit - nthawi ndiZotsatira za DopplerMasensa opangidwa ndi makina. Masensa osakanikirana awa cholinga chake ndi kugwiritsa ntchito mphamvu za mitundu yonse iwiri ya masensa, kupereka miyeso yolondola komanso yodalirika ya kayendedwe ka madzi m'mikhalidwe yovuta yamadzi.

Pomaliza, kusankha gulu la sensor muDoppler ultrasound flow meterzimadalira mtundu wa madzi omwe akuyesedwa. Masensa a nthawi yoyendera ndi abwino kwambiri pamadzi oyera, pomwe masensa otengera Doppler effect ndi oyenera kwambiri pamadzi okhala ndi zinthu zopachikidwa. Kumvetsetsa magulu a masensa awa ndikofunikira kuti mainjiniya ndi ogwiritsa ntchito asankhe mita yoyendera ya Doppler yoyenera kwambiri pa ntchito zawo, kuonetsetsa kuti muyeso wa kuyenda ndi wolondola komanso wogwira mtima.
