Umgaqo-nkqubo wexesha lokuhamba
Umgaqo woMlinganiso:
IIxesha lokuhambaI-Correlation Principle isebenzisa into yokuba ixesha lokuhamba kwesignali ye-ultrasonic ichaphazeleka yi-velocity ye-carrier medium.Njengendadi ewela umlambo oqukuqelayo, umqondiso weultrasonic uhamba kancinci unyusa umsinga kunomsinga.
YethuTF1100 ultrasonic flow meterssebenza ngokwalo mgaqo we-transit-lime:
Vf = Kdt/TL
Apho:
Isantya seVcFlow
K: Qho
dt: Umahluko kwixesha lokubhabha
I-TL: Ixesha lokuThutha ngomsindo
Xa imitha yokuhambahamba isebenza, ii-transducer ezimbini zithumela kwaye zifumane imiqondiso ye-ultrasonic eyandiswe yi-multi beam ehamba kuqala ezantsi ngomsinga ize inyuke.Ngenxa yokuba isandi esiphakamileyo sihamba ngokukhawuleza ezantsi kunomlambo, kuya kubakho umahluko wexesha lokubhabha (dt).Xa ukuhamba kumile, umahluko wexesha (dt) ngunothi.Ngoko ke, ukuba nje sisazi ixesha lokuhamba ngenqwelomoya ezantsi kunye naphezulu, sinokusebenza umahluko wexesha, kunye nesantya sokuhamba (Vf) kusetyenziswa le fomula ilandelayo.
