Indlela Yokukhetha Imitha Yokugeleza Yesiteshi Esivulekile Se-Doppler

Ukukhetha imitha yokugeleza ye-Doppler evulekile efanele kubalulekile ekulinganisweni kokugeleza okunembile nokuthembekile ezimbonini ezahlukahlukene, ikakhulukazi ekuhlanzweni kwamanzi amdaka, ekuniseleni, nasekuqapheni imvelo. Amamitha okugeleza e-Doppler asebenzisa ubuchwepheshe be-ultrasonic ukukala ijubane lokugeleza koketshezi futhi awusizo kakhulu ekusetshenzisweni okubandakanya izinto eziqinile ezilengisiwe noma amabhamuza omoya. Nazi izinto ezibalulekile okufanele uzicabangele lapho ukhetha imitha yokugeleza ye-Doppler evulekile:

1. Ibanga Lokugeleza Nokunemba

Isici sokuqala okufanele usicabangele ububanzi bokugeleza kwemitha. Qinisekisa ukuthi imitha yokugeleza ye-Doppler iyakwazi ukusingatha ijubane lokugeleza elithile ekusetshenzisweni kwakho. Amamitha e-Doppler afaneleka kakhulu ekulinganiseni ukugeleza eziteshini ezivulekile lapho uketshezi luqukethe izinhlayiya ezilengayo noma amabhamuza omoya abonisa isignali ye-ultrasonic. Imitha kufanele inikeze ukunemba okudingekayo ohlelweni lwakho, okungase kuhluke kuye ngokusetshenziswa (isb., amanzi angcolile, amanzi esiphepho, noma ukungcola kwezimboni).

2. Uhlobo Loketshezi Nokusetshenziswa

Amamitha okugeleza e-Doppler asebenza kahle kakhulu uma uketshezi luqukethe izinto eziqinile noma amabhamuza alengayo, njengoba lezi zinto zisiza ukukhombisa isignali ye-ultrasonic. Kumanzi ahlanzekile, angenamabhamuza, i-electromagnetic noma ezinye izinhlobo zamamitha okugeleza zingase zifaneleke kakhulu. Qinisekisa ukuthi izakhiwo zoketshezi—njengokungcoliswa, izinga lokushisa, kanye nokwakheka kwamakhemikhali—ziyahambisana nobuchwepheshe be-Doppler. Lokhu kuzoqinisekisa ukulinganiswa okunembile futhi kugweme noma yikuphi ukuphazamiseka okungaphazamisa ukufundwa.

3. Izidingo Zokufaka Nokulungisa

Uma ukhetha imitha yokugeleza yesiteshi esivulekile se-Doppler, cabangela indawo yokufaka kanye nokulula kokusethwa. Amanye amamodeli angadinga izindawo ezithile zokufaka noma ukucushwa, njengaseziteshini ezinamaphethini okugeleza ahambisanayo. Ngaphezu kwalokho, ukulula kokugcinwa kubalulekile, njengoba kungadingeka ukulinganisa noma ukuhlanza njalo, ikakhulukazi emanzini angcolile noma ezindaweni zokusebenza zezimboni lapho udoti unganqwabelana khona. Funa amamitha anikeza ukufakwa okulula ukusetshenziswa kanye nezidingo zokulungisa eziphansi, njengoba lokhu kuzosiza ukunciphisa isikhathi sokusebenza esingasebenzi.

Ngizokwethula imitha yethu yokugeleza yesiteshi esivulekile se-UOC ukuze uyibhekisele. Uchungechunge lwe-UOC luyimitha yokugeleza yesiteshi esivulekile se-ultrasonic eklanyelwe ukulinganisa ukugeleza okunembile eziteshini ezivulekile, esetshenziswa kabanzi ekuniseleni kwezolimo.

Uchungechunge lwe-Ultrasonic Open Channel Flow Meter (UOC)

IUchungechunge lwe-UOCiyimitha yokugeleza yesiteshi esivulekile se-ultrasonic esuselwe kude eyenzelwe ukulinganisa ukugeleza okunembile eziteshini ezivulekile. Yakhiwe izingxenye ezimbili: i-host efakwe odongeni enesibonisi kanye nekhiphedi yokuhlela, kanye ne-probe okumele ifakwe ngqo ngaphezu kwendawo eqashwe yiwo. Kokubili i-host kanye ne-probe zinesakhiwo sepulasitiki esingavuzi, okwenza kube okuqinile futhi okuthembekile ezinhlelweni ezahlukahlukene.

Izici Eziyinhloko:

• Ukunemba Okuphezulu Kokuthola:Ilinganisa ukushintsha kokugeleza ngokunemba okungu-1mm.
• Ukufakwa Okuguquguqukayo:Iyahambisana nezinhlobo ezahlukene zama-weirs nama-flumes, njenge-Parshall, i-V-Notch, kanye nama-weirs angunxande.
• Isibonisi Esithuthukisiwe:Isikrini sokuthinta esinombala esinobukhulu obuphezulu esingamasentimitha angu-5, esimelana namabala amanzi anamafutha, sinikeza imiphumela yokubonisa yesimanje.
• Izinketho Zokukhipha Eziguquguqukayo:IhlinzekaUmphumela ongu-4-20mAfuthiI-RS485 (MODBUS-RTU)ukuxhumana okulandelanayo, kuze kufike ku-Ama-relay angu-5 angahlelwangama-alamu.
• Amandla okuhamba ibanga elide:Ubude bekhebula phakathi kweprobe kanye nomsingathi bunganwebeka kuze kufike ku-Amamitha ayi-1000.
• Ihlala Njalo Futhi Imelana Namakhemikhali:I-probe inesilinganiso se-IP68 futhi yenziwe ngezinto ezimelana namakhemikhali anamandla.
• Izinketho Zamandla:Usekelo lokunikezwa kwamandla kagesi e-AC nase-DC, kanye newashi elisebenza nge-super-capacitor elakhelwe ngaphakathi elingadingi ukushintshwa kwebhethri impilo yonke.

Isiphetho

Ukukhetha imitha yokugeleza ye-Doppler evulekile efanele kuhilela ukucabangela izici ezifana nobubanzi bokugeleza, izici zoketshezi, kanye nezidingo zokufakwa. Ngokuqonda izidingo ezithile zesicelo sakho, ungakhetha imitha yokugeleza enikeza izilinganiso ezithembekile nezinembile kanye nokusebenza kwesikhathi eside.
