1. Impembelelo yecandelo lombhobho othe tye ongasentla nongasentla kwindlela yokulinganisa ukuchaneka kwe-ultrasonic flowmeter. I-calibration coefficient K ngumsebenzi wenombolo kaReynolds. Xa isantya sokuhamba singalingani ukusuka kwi-laminar flow ukuya kwi-turbulent flow, i-calibration coefficient K iya kutshintsha kakhulu, nto leyo ebangela ukwehla kokuchaneka kokulinganisa. Ngokweemfuno zokusetyenziswa, i-ultrasonic flow meter transducer kufuneka ifakwe kwicandelo lombhobho othe tye ongasentla we-10D, icandelo lombhobho othe tye ongasentla kwindawo ye-5D, ukuze kubekho iipompo, iivalvu kunye nezinye izixhobo xa ubude becandelo lombhobho othe tye buxhomekeke kubude, iimfuno "zomgama ukusuka kwi-turbulence, i-vibration, umthombo wobushushu, umthombo wengxolo kunye nomthombo we-ray kangangoko kunokwenzeka". Ukuba kukho iipompo, iivalvu kunye nezinye izixhobo ezingaphezulu kwendawo yokufakela ye-ultrasonic flow meter transducer, icandelo lombhobho othe tye kufuneka libe ngaphezulu kwe-30D. Ke ngoko, ubude becandelo lombhobho othe tye yeyona nto iphambili ukuqinisekisa ukuchaneka kokulinganisa.
2. Impembelelo yezixhobo zeparameter yepayipi ekuchanekeni kokulinganisa kwe-ultrasonic flowmeter. Ukuchaneka kokuseta iparameter yepayipi kunxulumene ngokusondeleyo nokuchaneka kokulinganisa. Ukuba useto lwezinto kunye nobukhulu bombhobho aluhambelani nolwenene, luya kubangela impazamo phakathi kwendawo yethiyori ye-flow pipeline cross-sectional kunye nendawo ye-flow cross-sectional, nto leyo ekhokelela kwiziphumo zokugqibela ezingachanekanga. Ukongeza, isithuba sokukhupha umoya phakathi kwe-ultrasonic flow meter transducer sisiphumo sokubala ngokubanzi iiparameter ezahlukeneyo ezifana nolwelo (isantya sesandi, i-dynamic viscosity), umbhobho (izinto kunye nobukhulu), kunye nendlela yokufaka ye-transducer, njl.njl., kwaye umgama wokufaka we-transducer uyaphambuka, nto leyo eya kubangela iimpazamo ezinkulu zokulinganisa. Phakathi kwazo, umgama wokuseta kunye nokufakwa kwe-warp yangaphakathi yombhobho unempembelelo ebonakalayo ekuchanekeni kokulinganisa. Ngokwedatha efanelekileyo, ukuba impazamo yangaphakathi ye-longitude yombhobho yi-±1%, iya kubangela impazamo yokuhamba malunga ne-±3%; Ukuba impazamo yomgama wokufaka yi-±1mm, impazamo yokuhamba iya kuba ngaphakathi kwe-±1%. Kuyabonakala ukuba kuphela ngokuseta ngokuchanekileyo iiparameter zepayipi apho i-ultrasonic flowmeter inokufakelwa ngokuchanekileyo kwaye impembelelo yeeparameter zepayipi ekuchanekeni kokulinganisa inokuncipha.
3, impembelelo yesikhundla sokufakelwa kwe-transducer yemitha yokuhamba kwe-ultrasonic ekuchanekeni kokulinganisa. Kukho iindlela ezimbini zokufaka i-transducer: uhlobo lokubonakalisa kunye nohlobo oluthe ngqo. Ukuba ukusetyenziswa kwesantya sesandi sokufaka ngqo kukufutshane, amandla esignali anokwandiswa.
4. Impembelelo yearhente yokudibanisa ekuchanekeni kokulinganisa. Ukuze kuqinisekiswe ukudibana ngokupheleleyo nombhobho, xa kufakwa i-transducer, umaleko wearhente yokudibanisa kufuneka ugqunywe ngokulinganayo kumphezulu wombhobho, kwaye ubukhulu ngokubanzi buyi (2mm - 3mm). Amaqamza kunye neegranules kwi-coupler ziyasuswa ukuze umphezulu we-emitter we-transducer unamathele ngokuqinileyo eludongeni lwetyhubhu. Ii-flowmeters zokulinganisa amanzi ajikelezayo zifakelwa kakhulu eWells, kwaye okusingqongileyo kumanzi kwaye ngamanye amaxesha kugcwele amanzi. Ukuba kusetyenziswa iarhente yokudibanisa ngokubanzi, iya kusilela ngexesha elifutshane, nto leyo echaphazela ukuchaneka kokulinganisa. Ke ngoko, kufuneka kukhethwe i-coupler ekhethekileyo engangeni manzi, kwaye i-coupler kufuneka isetyenziswe kwixesha elisebenzayo, ngokubanzi iinyanga ezili-18. Ukuqinisekisa ukuchaneka kokulinganisa, i-transducer kufuneka ibuyiselwe rhoqo kwiinyanga ezili-18 kwaye i-coupler kufuneka itshintshwe.
