Hoʻohana ʻia kahi mika kahe ultrasonic ʻano ʻokoʻa manawa transit me ka hoʻohana ʻana i nā transducers A pālua (nā mea ʻike A a me B ma ke kiʻi ma lalo), kahi e hoʻouna a loaʻa ai nā nalu ultrasonic ma ke ʻano ʻē (a i ʻole i ka manawa like). Holo wikiwiki ka hōʻailona i uka ma mua o uka i loko o ke kahe, a ʻo ka ʻokoʻa manawa he ʻole ke kū mālie ke kahe. No laila, inā e ana ʻia ka manawa o ka hoʻolaha ʻana o ke kahe ma lalo a me ke kahe kūʻē, hiki ke loaʻa ka waiwai ʻokoʻa △t. A laila, e like me ka pilina ma waena o △ T a me ka wikiwiki V, hiki ke ana ʻia ka wikiwiki awelika o ka medium ma ke ʻano ʻole, a hiki ke helu ʻia ke kahe nui Q e like me ka ʻāpana ʻāpana.
V = K * △ t
Q=S×V, kahi he mau ʻo K a ʻo S ka ʻāpana ʻāpana i loko o ka paipu.
He kūpono ka mika kahe ultrasonic manawa transit no ke ana ʻana i ka wai maʻemaʻe i loko o kahi paipu piha i pani ʻia, a ʻo ka nui o nā ʻāpana i hoʻokuʻu ʻia a i ʻole nā pehu i loko o ka wai i ana ʻia ma lalo o 5.0%. Hiki ke hoʻohana nui ʻia kēia ʻano mika kahe i nā wai ma lalo.
