1. Impembelelo yecandelo lombhobho onyukayo nasezantsi kwinqanaba lombhobho ochanekileyo ekuchanekeni komlinganiselo we-ultrasonic flowmeter.I-coefficient yokulinganisa K ngumsebenzi wenombolo yeReynolds.Xa isantya sokuhamba singalingani ukusuka kwi-laminar ukuya kwisiphithiphithi sokuqukuqela, i-coefficient yokulinganisa K iya kutshintsha kakhulu, okukhokelela ekunciphiseni kokulinganisa ukuchaneka.Ngokweemfuno zokusetyenziswa, i-ultrasonic flow meter meter transducer kufuneka ifakwe kwicandelo lombhobho othe tye we-10D, icandelo lombhobho othe tye osezantsi we-5D, ukwenzela ubukho beempompo, iivalve kunye nezinye izixhobo xa ubude bombhobho othe tye. icandelo lombhobho, iimfuno "zomgama ukusuka kwisiphithiphithi, ukungcangcazela, umthombo wobushushu, umthombo wengxolo kunye nomthombo wemitha kangangoko kunokwenzeka".Ukuba kukho iimpompo, iivalve kunye nezinye izixhobo eziphakamileyo kwindawo yokufakela i-ultrasonic flow meter meter transducer, icandelo lombhobho elithe ngqo lifuneka ukuba libe ngaphezu kwe-30D.Ngoko ke, ubude becandelo lombhobho elichanekileyo yinto ephambili yokuqinisekisa ukuchaneka komlinganiselo.
2. Impembelelo yezixhobo zepharamitha yepayipi ekuchanekeni kokulinganisa kwe-ultrasonic flowmeter.Ukuchaneka kokumisela ipharamitha yepayipi kuhambelana ngokusondeleyo nokuchaneka komlinganiselo.Ukuba ukusetwa kwezinto kunye nobukhulu bombhobho akuhambelani neyona nto, kuya kubangela impazamo phakathi kwendawo yokuwela i-pipeline ye-theory kunye neyona ndawo iguquguqukayo, ekhokelela kwiziphumo ezingachanekanga zokugqibela.Ukongeza, isithuba sokukhutshwa phakathi kwe-ultrasonic flow meter meter transducer sisiphumo sokubala ngokubanzi kweeparamitha ezahlukeneyo ezifana nolwelo (isantya sesandi, i-viscosity eguquguqukayo), umbhobho (izinto eziphathekayo kunye nobukhulu), kunye nendlela yokufakela i-transducer, njl. kunye nomgama wofakelo we-transducer uyaphambuka, okuya kubangela iimpazamo ezinkulu zokulinganisa.Phakathi kwabo, ukusetwa kunye nomgama wofakelo we-warp yangaphakathi yombhobho unempembelelo ebonakalayo ekuchanekeni komlinganiselo.Ngokwedatha efanelekileyo, ukuba impazamo yelongitude yangaphakathi yombhobho yi-±1%, iya kubangela malunga ne-±3% yempazamo yokuhamba;Ukuba impazamo yomgama wofakelo yi-±1mm, impazamo yokuqukuqela iya kuba ngaphakathi ±1%.Ingabonwa ukuba kuphela ngolungiselelo oluchanekileyo lweeparitha zombhobho apho i-flowmeter ye-ultrasonic ifakwe ngokuchanekileyo kwaye impembelelo yeeparitha zepayipi ekuchanekeni kokulinganisa ingancitshiswa.
I-3, impembelelo ye-ultrasonic flow meter meter transducer isikhundla sofakelo ekuchanekeni komlinganiselo.Kukho iindlela ezimbini zokufakela i-transducer: uhlobo lokubonisa kunye nohlobo oluthe ngqo.Ukuba ukusetyenziswa kohambo lwesantya sesandi esinyuka ngokuthe ngqo lufutshane, amandla ophawu anokwandiswa.
4. Impembelelo ye-arhente yokudibanisa ekuchanekeni komlinganiselo.Ukuze kuqinisekiswe uqhagamshelwano olupheleleyo kunye nombhobho, xa ufaka i-transducer, umaleko we-agent yokudibanisa kufuneka uhlanganiswe ngokulinganayo phezu kombhobho, kunye nobukhulu obuqhelekileyo (2mm - 3mm).Amaqamza kunye neegranules kwi coupler zisuswe ukwenzela ukuba umphezulu emitter we transducer idityaniswe ngokuqinileyo eludongeni ityhubhu.Ii-Flowmeters zokulinganisa amanzi ajikelezayo zifakwe ikakhulu kwi-Wells, kwaye okusingqongileyo kumanzi kwaye ngamanye amaxesha kukhukulisekile.Ukuba i-arhente yokudibanisa ngokubanzi isetyenzisiweyo, iya kusilela ngexesha elifutshane, ichaphazela ukuchaneka komlinganiselo.Ke ngoko, i-coupler ekhethekileyo engenamanzi kufuneka ikhethwe, kwaye i-coupler kufuneka isetyenziswe kwixesha elisebenzayo, iinyanga ezili-18 ngokubanzi.Ukuqinisekisa ukuchaneka komlinganiselo, i-transducer kufuneka iphinde ifakwe rhoqo kwiinyanga ezili-18 kwaye i-coupler kufuneka itshintshwe.
