I-Ultrasonic open channel flowmeter kunye ne-Doppler open channel flowmeter

I-ultrasonic evulekileyo ye-flowmeter yetshaneli

Ukusebenzisa iteknoloji yetshaneli evulekileyo, ngokusekelwe kwindlela yokubala inqanaba lokuhamba kwamanzi, isantya sokuhamba sifunyanwa ngokulinganisa ukuphakama kwenqanaba lolwelo, ukudibanisa ubungakanani bejometri yegroove eqhelekileyo ye-weir, i-slope coefficient, ukuchaneka kwetshaneli, i-hydraulic ramp, i-vertical plane coefficient yokulungiswa kwesantya sokuhamba, uze ubale nge-microprocessor engaphakathi kwesixhobo. Ngenxa yokulinganisa okungahambelaniyo, ii-flowmeter zetshaneli evulekileyo zingasetyenziswa kwiindawo ezinzima. Phantsi kolawulo lwe-microcomputer, i-flowmeter yetshaneli evulekileyo ithumela kwaye ifumane amaza e-ultrasonic, kwaye ibala umgama phakathi kwe-flowmeter yetshaneli evulekileyo kunye nomphezulu wolwelo olinganisiweyo ngokwexesha lokudlulisa, ukuze kufumaneke ukuphakama kwenqanaba lolwelo. Ngenxa yokuba kukho ubudlelwane obuthile obulinganayo phakathi kwenqanaba lolwelo kunye nesantya sokuhamba, isantya sokuhamba kolwelo u-Q sinokufunyanwa ngokwefomula yokubala.

I-Doppler evulekileyo yetshaneli yokuhambahamba

Indlela yokulinganisa uqhagamshelwano iyasetyenziswa, i-sensor ibekwa ezantsi kwetshaneli, kwaye phakathi kwezi probes zimbini, inkqubo ibala isantya sokuphuma ngokwesiphumo sexesha leDoppler, ize iguqule ukuhamba okukhawulezileyo kwindawo enqamlezileyo yendawo ye-sensor ngokwefomyula.
