Indawo yokukhetha i-flowmeter ye-ultrasonic kufuneka iqwalasele ezi zinto zilandelayo: umbhobho opheleleyo, ukuhamba okuzinzileyo, umlinganiselo, ubushushu, uxinzelelo, ukuphazamiseka njalo njalo.
1. umbhobho opheleleyo: Khetha icandelo lombhobho elizaliswe zizinto zolwelo ezisemgangathweni ofanayo, uthumelo olulula ukulwelwa nge-ultrasonic, njengecandelo lombhobho othe nkqo (ukuhamba kolwelo phezulu) okanye icandelo lombhobho othe tye.
2. ukuhamba okuzinzileyo: umgama wokufakelwa kufuneka ukhethwe phezulu ngaphezu kwe-10 ubukhulu bombhobho othe tye, ngezantsi ngaphezulu kwe-5 ubukhulu bombhobho othe tye ngaphandle kwengqiniba, ukunciphisa ububanzi kunye necandelo elinye lombhobho othe tye, indawo yokufakela kufuneka ibe kude nevalvu, ipompo, i-voltage ephezulu kunye ne-frequency converter kunye neminye imithombo yokuphazamiseka.
3. kuphephe ukufakwa kwe-external clamp-type ultrasonic flowmeter kwinkqubo yepayipi kwindawo ephezulu okanye kwipayipi ethe nkqo ephumayo (ulwelo luyehla)
4. Kwimibhobho evulekileyo okanye engazaliyo, imitha yokuhamba kwamanzi kufuneka ifakwe kwicandelo lombhobho elinomfanekiso we-U.
5. ubushushu kunye noxinzelelo lwendawo yokufakela kufuneka zibe ngaphakathi koluhlu olunokusebenza ngalo isenzi.
6. qwalasela ngokupheleleyo imeko yokulinganisa udonga lwangaphakathi lombhobho: nangona ukhetho lokufakelwa kombhobho ongalinganiyo, ukuba alukwazi ukuhlangabezana, ukulinganisa kunokuthathwa njengengqiniba ukuze kulinganiswe ngcono.
7. Iisensors ezimbini ze-external clamp ultrasonic flowmeter kufuneka zifakwe kwicala elithe tye lomphezulu we-axial wepayipi, kwaye zifakwe kwindawo ethe tye yomphezulu we-axial ngaphakathi koluhlu lwe-±45° ukuthintela isiganeko semibhobho engonelisekanga, amaqamza okanye imvula kwinxalenye ephezulu yesensor ukuze kuchaphazele umlinganiselo oqhelekileyo. Ukuba ayinakufakelwa ngokuthe tye nangokulinganayo ngenxa yokunciphisa indawo yendawo yokufaka, i-ultrasonic flowmeter inokufaka isensor ngokuthe nkqo okanye kwi-Engela phantsi kwemeko yokuba inxalenye ephezulu yetyhubhu ayinamaqamza.
