Vula i-flowmeter yetshaneli

I-flowmeter ye-channel evulekileyo, ngokwemigaqo yokulinganisa eyahlukeneyo, yahlulwe ibe yi-ultrasonic open channel flowmeter kunye ne-Doppler evulekileyo ye-flowmeter ye-channel, zonke zikumjelo ovulekileyo okanye umlinganiselo wesiteshi sesixhobo sokujonga inkqubo yokuhamba kwamanzi.Inkqubo evulekileyo yokujonga i-flowmeter ye-channel, ilungele indawo yokugcina amanzi, umlambo, iprojekthi yogcino lwamanzi, unikezelo lwamanzi asezidolophini, ukucocwa kogutyulo, ukunkcenkceshela kwimihlaba yasefama, imithombo yamanzi kunye nolunye uxande, umjelo ovulekileyo wetrapezoid kunye nomlinganiselo wokuhamba kwe-culvert.Sele isetyenziswa kakhulu kwiminyaka yakutshanje.

Ultrasonic open channel flowmeter

Ukusebenzisa itekhnoloji yomjelo ovulekileyo, ngokusekelwe kwindlela yokubala inqanaba lokuhamba kwamanzi, izinga lokuhamba lifunyanwa ngokulinganisa ukuphakama komgangatho we-fluid, ukudibanisa ubungakanani bejometri yomgangatho we-weir groove, i-slope coefficient, ukuchaneka kwesiteshi, i-hydraulic ramp, i-coefficient yokulungiswa kwendiza ethe nkqo. yesantya sokuhamba, kwaye emva koko ubale nge-microprocessor ngaphakathi kwesixhobo.Ngenxa yomlinganiselo ongaqhagamshelwanga, ii-flowmeters zeshaneli ezivulekileyo zingasetyenziselwa kwiindawo ezinzima.Ngaphantsi kolawulo lwe-microcomputer, i-flowmeter ye-channel evulekileyo idlulisela kwaye ifumana i-ultrasonic wave, kwaye ibala umgama phakathi kwe-flowmeter ye-channel evulekileyo kunye nomgangatho wolwelo olulinganisiweyo ngokwexesha lokuhambisa, ukuze ufumane ukuphakama kwenqanaba lolwelo.Kuba kukho unxulumano oluthile phakathi komgangatho wolwelo kunye nesantya sokuqukuqela, izinga lokuqukuqela kolwelo Q linokufunyanwa ngokwefomula yokubala.

I-Doppler vula i-flowmeter yeshaneli

Indlela yokulinganisa uqhagamshelwano iyamkelwa, inzwa ibekwe ezantsi kwejelo, kwaye phakathi kweeprobe ezimbini, inkqubo ibala isantya sokuphuma ngaphandle ngokwexesha le-Doppler, kwaye emva koko iguqule ukuhamba ngokukhawuleza kwindawo ye-cross-sectional. indawo yoluvo ngokwefomula.
