Kumu o ke ana:
ʻO kaKaʻa-manawaHoʻohana ʻia ka Correlation Principle i ka ʻoiaʻiʻo e pili ana ka manawa o ka lele ʻana o kahi hōʻailona kani ultrasonic e ka wikiwiki o ke kahe o ka mea lawe.E like me ka ʻauʻau ʻauʻau e hana ana ma kēlā ʻaoʻao o ka muliwai e kahe ana, ʻoi aku ka lohi o kahi hōʻailona kani ultrasonic i uka ma mua o ke kahawai.
ʻO kā mākouTF1100 kani ultrasonic kahe ana mikae hana e like me kēia kulekele transit-lime:

Vf = Kdt/TL
Ma hea:
VcFlow velocity
K: Mau
dt: ʻokoʻa i ka manawa lele
TL: ʻO Ave rage Transit Time

Ke hana ka mika kahe, hoʻouna a loaʻa i nā mea transducers ʻelua nā hōʻailona kani ultrasonic i hoʻonui ʻia e nā kukuna lehulehu e holo mua i lalo a laila i uka.No ka holo wikiwiki ʻana o ke kani ultra i lalo o ke kahawai, ʻokoʻa ka manawa o ka lele (dt).Ke kū mālie ke kahe, ʻo ka ʻokoʻa o ka manawa (dt) ʻaʻole.No laila, ʻoiai mākou e ʻike i ka manawa o ka lele ʻana i lalo a i uka, hiki iā mākou ke hana i ka ʻokoʻa o ka manawa, a laila ka wikiwiki o ke kahe (Vf) ma o ke ʻano ma lalo nei.
