Yimaphi Amanzi Afanelekela Ama-Clamp-On Doppler Flowmeters?

Ama-flowmeter e-Clamp-on Dopplerzifanelekela kuphela uketshezi oluqukethe inani elithile lama-acoustic scatterer, zithembele esimisweni somphumela we-Doppler ukukala ijubane lokugeleza ngokuthola ukushintsha kwemvamisa kumaza omsindo aboniswa ama-scatterer (isb., izinhlayiya, amabhamuza) oketshezini. Ngezansi kunezinhlobo ezithile zoketshezi kanye nezimo ezibalulekile zokusetshenziswa kwazo:

Izinhlobo Ezifanele Zoketshezi Eziyinhloko
1. Uketshezi Olunezinhlayiya Eziqinile
Imidiya Ejwayelekile:
Indle, udaka, i-pulp yamaminerali, i-pulp yamaphepha, amanzi angcolile ezimbonini (aqukethe izinhlayiya ezifana ne-sediment, imfucumfucu, imicu, ngokuvamile enobukhulu bezinhlayiya obungu-≥30 μm).
Uketshezi olugcwele izinhlayiya embonini yokudla (isb., ujusi wezithelo one-pulp, amasoso, iziphuzo eziqukethe okusanhlamvu).
Ukumiswa embonini yamakhemikhali (isb., izingxube zezinhlayiya ze-catalyst, ama-pigment slurry).
Izidingo Eziyinhloko:
Ukuhlushwa kwezinhlayiya kumele kube ≥100 ppm ukuqinisekisa izimpawu zokukhanya ze-acoustic ezanele.
I-acoustic impedance yezinhlayiya kumele ihluke kakhulu kweyoketshezi (isb., izinhlayiya eziqinile zibonisa imiphumela emihle yokubonakalisa ngenxa yomehluko omkhulu we-impedance emanzini).
2. Uketshezi olunezibhamuza
Imidiya Ejwayelekile:
Ukugeleza kwegesi-uketshezi kwezigaba ezimbili (isb., uketshezi lwenqubo yezimboni olunamabhamuza omoya, uketshezi lokubilisa ubhiya).
Uketshezi oluxubile noma olunomoya (isb., ukungcola okuvela emathangini okungenisa umoya ekuhlanzweni kwamanzi amdaka).
Okucatshangelwayo:
Amabhamuza kumele ahlakazwe ngokulinganayo oketshezini, kugwenywe “amaqoqo egesi” noma igesi ekhululekile ngokweqile (okungabangela ukusabalala kwesignali okungazinzile).
3. Uketshezi Oluyi-Turbid noma Olungacacile
Izimo Ezijwayelekile:
Uketshezi lapho izindlela zokulinganisa ezibonakalayo (isb., ama-magnetic flowmeter) zingasebenzi kahle ngenxa yokungakwazi ukungena kahle (isb., izixazululo zamakhemikhali ezinombala omnyama, amanzi anodaka).
Ama-paste noma ama-emulsion embonini yokudla (isb., isosi likashokoledi, amafutha ahlanganisiwe).
