Umgaqo-siseko wokusebenza: Indlela ii-Small-Diameter Ultrasonic Flowmeters ezisebenza ngayo
Eyona nto iphambili kwii-flowmeters ze-ultrasonic ezinobubanzi obuncinci yindlela yokuhamba, iteknoloji engangeneleliyo esusa isidingo sokuhamba kweendawo. Ii-transducers ezimbini ze-ultrasonic zifakelwe eludongeni lwangaphandle lombhobho (okanye zifakwe kumbhobho kwezinye iindlela ezixineneyo), zibekwe ukuze zithumele kwaye zithole imiqondiso ye-ultrasonic kuyo yonke indlela yokuhamba kolwelo. Xa ulwelo luhamba ngepayipi, lukhawulezisa uphawu lwe-ultrasonic oluhamba kwicala lokuhamba (ezantsi) kwaye lucothise uphawu oluhamba ngokuchasene nokuhamba (phezulu). Imitha ibala umahluko wexesha phakathi kwezi zibonakaliso zimbini; lo mahluko uhambelana ngokuthe ngqo nesantya solwelo, oluthi emva koko luguqulwe lube yisantya sokuhamba (ngesiqhelo kwiilitha ngomzuzu okanye ii-cubic metres ngeyure) kusetyenziswa indawo enqamlezileyo yombhobho.
Kwimibhobho enobukhulu obuncinci, olu yilo luluncedo kakhulu. Iimitha zemveli zoomatshini zihlala zinengxaki yokugeleza okuncinci—zinokuba namava “eendawo ezifileyo” apho isantya esiphantsi singaphumeleliyo ukufundwa ngokuchanekileyo, okanye iindawo zazo ezihambayo ziguga ngokukhawuleza ngenxa yokungqubana okungapheliyo.
