I-ultrasonic flowmeter yokukhetha indawo yokufakela kufuneka iqwalasele ezi zinto zilandelayo: umbhobho ogcweleyo, ukuhamba ngokuzinzile, ukulinganisa, ukushisa, uxinzelelo, ukuphazamiseka kunye nokunye.
1. umbhobho ogcweleyo: Khetha icandelo lombhobho elizaliswe ngumgangatho ofanayo wezinto ezilulwelo, ezilula kwi-ultrasonic transmission, njengecandelo lombhobho othe nkqo (ukuqukuqela kwamanzi ukuya phezulu) okanye icandelo lombhobho oxwesileyo.
2. ukuhamba okuzingileyo: umgama wofakelo kufuneka ukhethwe phezulu kumlambo omkhulu kunamaxesha ali-10 ubukhulu bombhobho othe tye, ezantsi kumlambo omkhulu kunamaxesha ama-5 obubanzi bombhobho othe tye ngaphandle kwengqiniba, ukucutha ubukhulu kunye nezinye icandelo lombhobho othe tye, indawo yofakelo kufuneka ibe kude. ukusuka kwivalve, impompo, amandla ombane aphezulu kunye nesiguquli samaza kunye neminye imithombo yokuphazamiseka.
3. kuphephe ukufakelwa kwe-clamp yangaphandle-uhlobo lwe-flowmeter ye-ultrasonic kwisixokelelwano semibhobho kwindawo ephezulu okanye umbhobho othe nkqo osimahla wokuphuma (ukugeleza kolwelo ukuhla)
4. kwimibhobho evulekileyo okanye enesiqingatha, imitha yokuhamba kufuneka ifakwe kwicandelo lombhobho we-U.
5. iqondo lokushisa kunye noxinzelelo lwendawo yokufakela kufuneka ibe phakathi koluhlu olunokusebenza inzwa.
6. qwalasela ngokupheleleyo imeko yokulinganisa yodonga lwangaphakathi lombhobho: nangona ukukhethwa kofakelo lombhobho ongeyena umlinganiselo, ukuba awukwazi ukuhlangabezana, ukunyuswa kunokuthathwa njengentambo ukwenzela ukuchaneka kokulinganisa okungcono.
7. i-sensors ezimbini ze-clamp yangaphandle ye-flowmeter ye-ultrasonic kufuneka ifakwe kwicala elithe tye lombhobho we-axial surface, kwaye ifakwe kwindawo ethe tye ye-axial surface ngaphakathi koluhlu lwe-± 45 ° ukuthintela isiganeko semibhobho enganelisekanga, amaqamza. okanye imvula kwindawo ephezulu yenzwa ukuchaphazela umlinganiselo oqhelekileyo.Ukuba ayinakufakwa ngokuthe tye kunye ne-symmetrically ngenxa yokunciphisa indawo yokufakela indawo, i-flowmeter ye-ultrasonic ingafaka i-sensor vertically okanye kwi-Angle phantsi komqathango wokuba inxalenye ephezulu yombhobho ayinamaqamza.
