Umgaqo osisiseko we-ultrasonic laser ukusuka
I-ultrasonic open channel flowmeteryile: ngokwesivamvo se-ultrasonic efakwe kwi-weir (slot) isixhobo sokulinganisa ukuqukuqela, i-single-chip microcomputer kwi-open channel flow meter yenzelwe ukukhupha isignali ethile ye-electronic frequency ukukhuthaza icrystallization ye-piezoelectric kwi-probe Thumela isignali yedatha ye-ultrasonic. yefrikhwensi ekhethekileyo, kwaye uqale isibali-xesha ngexesha lokuthumela kwaye uqale nje ukubala ixesha. Isignali yedatha ye-ultrasonic isasazwa ngokwezinto ezilinganisiweyo zolwelo kwaye ibethe i-pole standard. Phakathi kwabo, inxalenye yabangela ukuba i-reflection echo yokuqala, kwaye inxalenye isasazeka emanzini kwakhona. Inxalenye yomboniso isasazeka kwicala elingasemva kwaye ingena kwi-probe, ibangela ukuba i-chip yeprobe ihambe, ibangele ukuguqulwa kwesandi, amandla omatshini ekinetic, kunye namandla ombane ukwenza ukuba iprobe iphume uphawu lokuqala lombane. Xa i-ultrasonic wave isasazeka kwakhona emanzini ifikelela kumphezulu wamanzi, kuba kukho umphunga (igesi) ngaphezu kwamanzi, ibangela ukuba i-reflection yesibini i-echo kwi-interface ye-vapor-liquid interface, kwaye i-echo ebonakalisiweyo iyahlakazeka kwaye ibonakaliswe umva. ikristale yepiezoelectric. Iprobe ikhupha enye imiqondiso yombane. Oko kukuthi, i-echo yokuqala ebonakalisiweyo ibangelwa kumphezulu wereferensi (intonga eqhelekileyo), kwaye eyesibini i-echo ebonakalisiweyo ibangelwa kumaleko ojongano lomphunga-ulwelo. Xa i-probe ifumana amaza abonakalisiweyo, iphelisa ngokukhawuleza ixesha. Ngeli xesha, ixesha lirekhodwa. Isixhobo sirekhoda ixesha losasazo lwe-wave ye-ultrasonic ukusuka ekuthumeleni ukuya ekwamkeleni. Kwaye t, ngokwefomula H: ht/t0, (h ngumlinganiselo wobude-ububanzi bomphezulu we-weir (umkhombe)) yinkalo yomlinganiselo wenkqubo evulekileyo ye-flowmeter probe ukuya kwinqanaba lolwelo H.
Umlinganiselo ochanekileyo ongadibananga: Inzwa ayichukumisi ulwelo, kwaye ayiyi kutshatyalaliswa kwaye ingcoliswe ngamanzi amdaka. I-sensor yisakhiwo segobolondo se-ABS esitywiniweyo, esinganyangekiyo kwi-alkali kunye ne-corrosion, kwaye sinokusebenza ixesha elide kwindawo yendalo emanzi kunye nebanda; Ukulinganisa ngoko nangoko umphezulu wamanzi olwelo: Isivamvo silinganisa ngoko nangoko inqanaba lemitha yolwelo lomphezulu wamanzi olwelo. Ayisebenzisi imithombo engatshintshiyo, enokuthi igweme ukuvala umbhobho wokudibanisa ngenxa yokusetyenziswa kwamaqula angatshintshiyo, izinto eziqinileyo ezimisiweyo kumanzi amdaka, isanti ecocekileyo, njl. njl., okubangela amaqula amileyo kunye nemigangatho yokulinganisa Umgca womgangatho wamanzi wetanki awuhambelani, okanye ufanelekile. ukukhenkceza ebusika, kuveliswa imitha yenqanaba le-alamu yobuxoki, ebangela ukulinganisa okungahambi kakuhle; Ukulungelelaniswa kwendawo yonke: Misela iiparitha eziphambili zepaneli yesixhobo ngokwebhodibhodi, enokuthi isetyenziswe kwiindawo ezahlukeneyo zokulinganisa amanzi. Ukusetyenziswa kwemigangatho eyahlukeneyo efana nokudityaniswa kwimisele yokunkcenkceshela yomhlaba kunye nemibhobho engaphantsi komhlaba ekhonkrithi;
Inkxaso yenkonzo eneenkcukacha: Naluphi na uxwebhu lubonisa indlela yofakelo lwepaneli yesixhobo, indlela yeparameter esisiseko, ulwakhiwo kunye nendlela yofakelo lwendlela yokulinganisa amanzi, kunye nomlinganiselo kunye nendlela yokuqinisekisa ukutenxa ngokupheleleyo kokuhamba; Umgangatho othembekileyo: Emva kweminyaka yokwenziwa, ukusebenza, kunye nesandi se
I-ultrasonic open channel flowmeters, izicelo ze-spot-spot ziqinisekisile ukuba iimpawu zemveliso zihlangabezana neemfuno zokulinganisa kwamanzi amdaka kunye nokuqinisekiswa.
