Litšobotsi tsa khoebo tsa ultrasonic open channel flow meter:
- Lethathamo la litekanyo le leholo, 'me tekanyo ea phallo e ke ke ea ntšoa kotsi ke metsi a ka morao a bohlale a libaka tse kholo le tsa tributary.
- Ha e lekanya, e ke ke ea ntšoa kotsi ke lintho tse tiileng tse emisitsoeng, lehlabathe le letle, li-bubble tsa mouoane le liphetoho tse kholo boemong ba metsi.
