Yintoni ekufuneka ihoywe yi-flowmeter ye-ultrasonic ngesandla xa ukhetha?

I-Handheld ultrasonic flowmeters ilinganisa ukuhamba kolwelo nge-clip-on sensor yangaphandle.Inkqubo yokufakela ilula, yonke i-interface yomatshini waseTshayina, kulula ukuyisebenzisa.Izinto eziluncedo ze-handheld ultrasonic flowmeter zezi:

I-1, umlinganiselo ongadibananga, ubungakanani obuncinci, ubunzima obulula, kulula ukuthwala.

I-2, ukufakwa kwenzwa kulula kwaye kulula, kusetyenziselwa ukulinganisa ubukhulu obuhlukeneyo bombhobho wesandi sesikhokelo sesandi.

I-3, inkqubo yokulinganisa ayifuni ukutshabalalisa umbhobho, akufuneki ukuyeka ukuvelisa, inzwa ayidibanisi nomgangatho olinganisiweyo, akukho kulahleka kwengcinezelo.

Ekuthengeni kufuneka ingqalelo:

I-1, ukuhlolwa kokusebenza okuchanekileyo

Inqanaba elichanekileyo kunye nomsebenzi Ngokweemfuno zokulinganisa kunye nokusetyenziswa kwenqanaba lokuchaneka kwesixhobo, ukufezekisa uqoqosho.Umzekelo, ukulungiselela urhwebo, ukunikezelwa kwemveliso kunye nomlinganiselo wamandla, izinga lokuchaneka kufuneka libe phezulu, njenge-1.0, 0.5, okanye ngaphezulu;Kulawulo lwenkqubo, khetha amanqanaba ahlukileyo achanekileyo ngokweemfuno zolawulo;Abanye babona nje ukuhamba kwenkqubo, akufuneki ukuba benze ulawulo oluchanekileyo kunye nezihlandlo zokulinganisa, unokukhetha inqanaba elisezantsi lokuchaneka.

2, imidiya enokulinganiswa

Xa ulinganisa umlinganiselo wokuhamba okuphakathi, uluhlu lwezixhobo kunye nobubanzi, iqondo elipheleleyo lokuhamba kweqondo lokuhamba kwe-ultrasonic flowmeter lingakhethwa kuluhlu lokulinganisa umlinganiselo ophakathi kwe-0.01-12m / s, kwaye uluhlu lubanzi.Ukukhethwa kweenkcukacha zesixhobo (umgangatho) akuyomfuneko ukuba kufane nombhobho wenkqubo, kufuneka kumiselwe ngokuhambelana nokuba uluhlu lokuhamba olulinganisiweyo, kuluhlu lwesantya sokuhamba, oko kukuthi, xa umyinge wokuhamba kwemibhobho uphantsi, awukwazi ukuhlangabezana Iimfuno zemitha yokuhamba okanye ukuchaneka kokulinganisa akunakuqinisekiswa kule nqanaba lokuhamba, kuyimfuneko ukunciphisa ububanzi besixhobo, ukwenzela ukuba kuphuculwe izinga lokuhamba kwi-tube, kwaye ufumane iziphumo zokulinganisa ezanelisayo.
