Open channel flowmeter, e like me ka ana okoa loina, ua maheleia i kani ultrasonic wehe auwai flowmeter a me Doppler wehe auwai flowmeter, lakou a pau i loko o ka hamama a me ke ana ana o ka wai kahe nenoaiu kiaʻi lako.ʻO ka ʻōnaehana nānā ʻana i ke kahawai kahe wai, kūpono no ka waihona, ka muliwai, ka papahana mālama wai, ka lako wai o ke kūlanakauhale, ka mālama ʻana i ka wai, ka ʻāina mahiʻai, nā kumu wai a me nā ʻāpana ʻē aʻe, trapezoid open channel a me nā ana kahe wai.Ua hoʻohana nui ʻia i nā makahiki i hala iho nei.
ʻO ka mīkini kani kani kani kani kani ultrasonic
Ke hoʻohana nei i ka ʻenehana ākea ākea, e pili ana i ke ʻano helu helu wai kahe, loaʻa ka kahe kahe ma ke ana ʻana i ke kiʻekiʻe o ke kiʻekiʻe o ka wai, e hui pū ana i ka nui geometric o ka weir groove maʻamau, coefficient slope, pololei channel, hydraulic ramp, vertical plane correction coefficient. o ka holo kahe, a laila e helu ana ma o ka microprocessor i loko o ka mea kani.Ma muli o ke ana hoʻopili ʻole, hiki ke hoʻohana ʻia nā kahe kahe wai hāmama i nā wahi ʻino.Ma lalo o ka mana o ka microcomputer, e hoʻouna a loaʻa ka hawewe kani ultrasonic ka kaila kahe hāmama, a me ka helu ʻana i ka mamao ma waena o ka flowmeter a me ka ʻili wai i ana ʻia e like me ka manawa hoʻouna, i loaʻa ai ke kiʻekiʻe o ka wai.No ka mea aia kekahi pilina pili ma waena o ka pae wai a me ke kahe kahe, hiki ke loaʻa ka kahe wai Q e like me ka helu helu.
ʻO Doppler hāmama kahe kahe ana
Hoʻohana ʻia ke ʻano ana o ka hoʻopili ʻana, waiho ʻia ka mea ʻike ma lalo o ke kahawai, a ma waena o nā ʻimi ʻelua, helu ka ʻōnaehana i ka wikiwiki o ka puka ʻana e like me ka hopena Doppler time, a laila hoʻololi i ke kahe koke ma o ka ʻāpana cross-sectional o ka ʻāpana ʻike e like me ke ʻano.
