Doppler ultrasonic flowmeter inoshandisa iyo fizikisi yeDoppler mhedzisiro, mune chero mvura inoyerera pamberi pediscontinuity icharatidzwa ultrasonic chiratidzo frequency shift (kureva, chiratidzo chechikamu musiyano), nekuyera mutsauko wechikamu, chiyero chekuyerera chinogona kuyerwa.Iyo frequency shift ibasa remutsetse weyero yekuyerera, iyo inosefa kuburikidza nedunhu kuti ibudise yakagadzikana, inodzokororwa, uye mutsara chiratidzo.Aya discontinuities anogona kunge akamiswa mabubbles, solids, kana interfaces nekuda kwekukanganiswa kwemvura.Masensa anogadzira uye anogashira ultrasonic masaini, uye transmitters maitiro masaini kuti ape analog kubuda kwekuyerera uye cumulant kuratidza.Lanry Instruments Doppler ultrasonic flowmeter ine yakasarudzika dhijitari yekusefa tekinoroji uye frequency modulation demodulation tekinoroji, ichigadzira otomatiki iyo yakagamuchirwa waveform chiratidzo, inogona kuyera tambo yepombi, uye pombi vibration haina kunyatso kuomarara.Kuti uise sensor, iyo kumusoro uye yakadzika kwenzvimbo yekuisa inofanira kuva yakareba yakatwasuka pombi chikamu.Kazhinji, kumusoro kwerukova kunoda 10D yepombi yakatwasuka, uye yakadzika inoda 5D yepombi yakatwasuka.D ndiyo dhayamita yepombi.
Doppler ultrasonic flowmeters yakanyatsogadzirirwa kuyerwa kwemvura ine tsvina yakawanda senge yakasimba particles kana mabubbles kana kuti yakasviba mvura.Inonyanya kushandiswa mundima dzinotevera:
1) Yekutanga tsvina, tsvina inotakura mafuta, tsvina, tsvina inotenderera mvura, nezvimwe.
2) Liquid midhiya ine zvimedu uye mabhubhu mukugadzirwa kwemaindasitiri, senge makemikari slurry, muchetura tsvina mvura, nezvimwe.
3) Liquid ine silt uye zvimedu, senge slag fluid, mafuta munda wekuchera grouting fluid, port dredging, nezvimwe.
4) marudzi ese e turbid slurry, senge pulp, pulp, crude oil, nezvimwe.
5) Kuiswa kwe-on-line kunovharika, iyo inonyanya kukodzera kuyera kuyerera kwemvura yepakutanga yepombi yakakura.
6) Munda wekuyerera calibration uye kuyerera bvunzo yeiyo pamusoro inoshanda svikiro, uye chiyero chemunda chemamwe maflowmeters.
