Iintsilelo zangoku ze-ultrasonic flowmeter kukuba uluhlu lobushushu bomzimba ohambayo olinganisiweyo lunqunyelwe kukuxhathisa kobushushu be-aluminium yokutshintshiselana kwamandla e-ultrasonic kunye nezinto zokudibanisa phakathi kwe-transducer kunye nombhobho, kwaye idatha yokuqala yesantya sokudlulisa isandi somzimba ohambayo olinganisiweyo kumaqondo obushushu aphezulu ayiphelelanga. Okwangoku, iTshayina inokusetyenziswa kuphela ukulinganisa ulwelo olungaphantsi kwama-200℃. Ukongeza, umgca wokulinganisa we-ultrasonic flowmeter uyinkimbinkimbi ngakumbi kunowe-general flowmeter. Oku kungenxa yokuba izinga lokuhamba kolwelo kwi-industrial metering ngokubanzi lidla ngokuba ziimitha ezimbalwa ngomzuzwana, kwaye isantya sokusasazeka kwezandi kwi-liquid simalunga ne-1500m/s, kwaye utshintsho kwisantya sesandi oluziswa lutshintsho kwizinga lokuhamba komzimba ohambayo olinganisiweyo nalo luyi-10-3 orders of magnitude. Ukuba ukuchaneka kwesantya sokuhamba komlinganiselo kufuneka kube yi-1%, ukuchaneka kokulinganisa isantya sesandi kufuneka kube yi-10-5 ~ 10-6 orders yobukhulu, ngoko ke kufuneka kubekho umgca wokulinganisa ogqibeleleyo ukuze kufezekiswe, nto leyo ekwayi-ultrasonic flowmeter enokuba sisicelo esisebenzayo phantsi kophuhliso olukhawulezileyo lwetekhnoloji yesekethe edibeneyo.
(1) Uluhlu lokulinganisa ubushushu be-ultrasonic flowmeter aluphezulu, kwaye ngokubanzi lunokulinganisa kuphela ulwelo olunobushushu obungaphantsi kwama-200°C.
(2) Amandla okungasebenzi kakuhle okulwa nokuphazamiseka. Kulula ukuphazamiseka yingxolo ye-ultrasonic exutywe namaqamza, isikali, iipompo kunye neminye imithombo yesandi kwaye ichaphazela ukuchaneka kokulinganisa.
(3) Icandelo lombhobho othe tye lifuneka kakhulu kwi-20D yokuqala kunye ne-5D yokugqibela. Ngaphandle koko, ukusasazwa kukubi kwaye ukuchaneka kokulinganisa kuphantsi.
(4) Ukungaqiniseki kofakelo kuya kuzisa impazamo enkulu ekulinganisweni kokuhamba kwamanzi.
(5) Ukulinganiswa kombhobho wokulinganisa kuya kuchaphazela kakhulu ukuchaneka kokulinganisa, okubangela iimpazamo ezinkulu zokulinganisa, kwaye kungabikho mboniso wokuhamba kwamanzi kwiimeko ezinzima.
(6) Inqanaba lokuthembeka nokuchaneka aliphezulu (ngokubanzi malunga ne-1.5 ~ 2.5), kwaye ukuphindaphindwa kwayo kuphantsi.
(7) Ubomi benkonzo obufutshane (ukuchaneka ngokubanzi kunokuqinisekiswa unyaka omnye kuphela).
(8) I-Ultrasonic flowmeter isetyenziswa ngokulinganisa isantya solwelo ukuze ibone ukuhamba komthamo, ulwelo kufuneka lulinganise ukuhamba kobunzima balo, umlinganiselo wesixhobo sokuhamba kobunzima ufunyanwa ngokuphindaphinda ukuhamba komthamo ngoxinano olubekwe ngokwenziwa, xa ubushushu bolwelo butshintsha, uxinano lolwelo lutshintshiwe, ixabiso loxinano olubekwe ngokwenziwa, alunakuqinisekisa ukuchaneka kokuhamba kobunzima. Kuphela xa isantya solwelo silinganiswa ngaxeshanye, uxinano lolwelo lulinganiswa, kwaye izinga lokuhamba kobunzima bokwenyani linokufunyanwa ngokubala.
(9) Ukuchaneka komlinganiselo weDoppler akuphezulu. Indlela yeDoppler ifanelekile kwiilwelo ze-biphase ezinomxholo ongalinganiyo kakhulu, njengokungcola okunganyangwanga, ulwelo lokukhupha imveliso efektri, ulwelo lwenkqubo engcolileyo; Ayiqhelekanga ukuba ifaneleke kwiilwelo ezicocekileyo kakhulu.
