1. Ukukhethwa kweendawo zokulinganisa kufuneka kube kude kakhulu neempompo, iivalvu kunye nezinye izixhobo kangangoko kunokwenzeka ukuze kuthintelwe ukuphazamiseka. Kubalulekile ukulinganisa ulwelo oluthe tyaba kangangoko kunokwenzeka ukuze kuthintelwe impazamo yokulinganisa ebangelwa kukuhamba kwamanzi okuguquguqukayo.
2. Xa i-sensor ifakiwe kumbhobho othe tye, kufuneka ibe ne-engile encinci ye-20° kunye nomgca othe nkqo. Ukuze kuthintelwe ukuphazamiseka komsebe xa igesi iqokelelana phezulu kumbhobho.
3. Kuphephe ukulinganisa kwindawo yokutshintsha kwenani likaReynolds.
4. Akufanele kubekho imithungo yokuwelda, akukho kungcangcazela kwaye kungabikho mithombo yokuphazamiseka kwe-electromagnetic kwindawo yokulinganisa; Iiparameter zoyilo lombhobho wovavanyo kufuneka zibonelelwe, kwaye ububanzi bangaphandle kunye nobukhulu bodonga lombhobho kufuneka buhlolwe ngee-calipers okanye iteyipu yentsimbi kunye neegeyiji zobukhulu be-ultrasonic kwindawo. Ukuze kuncitshiswe iimpazamo, ububanzi bangaphandle kunye nobukhulu bodonga lombhobho kufuneka bulinganiswe kwiindawo ezininzi kwaye ixabiso lawo eliqhelekileyo kufuneka lithathwe.
5. Umbhobho kufuneka ufane kwaye ube mkhulu, kube lula ukuwusasaza nge-ultrasound.
6. Umphezulu wombhobho wesinyithi apho kuza kufakelwa khona i-transducer kufuneka upholishwe kathathu kwindawo yeprobe ukuze kususwe ipeyinti yomhlwa, ukuze umphezulu wodonga lombhobho ube bushelelezi kwaye uthe tyaba, uveze umphezulu wokuqala wesinyithi sombhobho kwaye ugcine i-arc yokuqala.
7. Xa kuthelekiswa ne-fluid ultrasonic flowmeter, isignali yokulinganisa isengozini enkulu yokuphazamiseka kwesignali yengxolo, ukuba umlinganiselo wesignali-kwingxolo ungaphantsi kwe-10:1, ayinakulinganiswa ngokuchanekileyo. Ke ngoko, ngaphambi kokulungisa i-transducer kumbhobho, ukuze kuncitshiswe impembelelo yesignali yengxolo yombhobho kwiziphumo zokulinganisa, ifilimu yokudibanisa igesi kufuneka incamathiselwe eludongeni lwangaphandle lombhobho, kwaye ukuveliswa kwamaqamza kufuneka kuncitshiswe ukuthintela umoya, uthuli kunye nomhlwa ekungeneni; Ukuba amaqamza aveliswa, amaqamza kufuneka aphulwe ukuze kukhutshwe igesi.
8. Cinga ngokupheleleyo ngemeko yokufakwa kwesalfure, ukwakheka kunye nokugqwala kwipayipi, kwaye ukhethe icandelo lombhobho elingenasediment kunye nokugqwala kwipayipi kangangoko kunokwenzeka ukuze ulinganise.
9. Isixhobo kufuneka sifakwe embindini we-transducer ukuze kungabi lula ukusityibiliza.
