ʻO ka mīkini kani kani kani
Nā pōmaikaʻi o ka mīkini kahe acoustic:
1. Ke ana hookahe ole
2. ʻAʻohe ana keakea kahe, ʻaʻohe poho puʻe.
3. Hiki ke ana i ka wai non-conductive.
4. Ka laulā paipu ākea
5. Hiki ke ana ʻia ka wai, ke kinoea, ka ʻaila, nā ʻano media āpau, ākea loa kāna kahua noi.
Nā hemahema o ka ultrasonic flowmeter:
1. Aia kekahi mau palena i ke ana ʻana i ka media wela kiʻekiʻe.
2. Nā koi kiʻekiʻe no ka mahana o ke kahua kahe.
3. Pono ka lōʻihi o ka pauku paipu pololei.
He nui nā pono o ka flowmeter electromagnetic i ka kahe wai a hoʻohana nui ʻia i nā ʻoihana like ʻole.
1 ʻAʻohe obstructing flow parts i loko o ke ana paipu, ʻaʻohe puʻe poho, a ʻo nā koi o ka ʻāpana paipu pololei he haʻahaʻa;
2 Kiʻekiʻe ana pololei, ikaika paʻa, ikaika anti-vibration interference hiki;
3 ʻAʻole pili ke ana i nā loli i ka nui o ka wai, viscosity, wela, kaomi a me ka conductivity;
4 Me nā ʻano electrodes a me nā koho lining, kūpaʻa ikaika i ka corrosion dielectric.
ʻOiaʻiʻo, loaʻa i nā flowmeter electromagnetic ko lākou mau palena ponoʻī:
1 Pono ka mea ana i kekahi conductivity (ʻoi aku ka nui ma mua o 5us/cm), a aia kekahi mau koi no ke ana ʻana i ka wikiwiki holo mua (ʻoi aku ka nui ma mua o 0.5m/s).
2 Ua kaupalena ʻia ka mahana o ke ana ʻana e ka mea lining, a ʻaʻole maikaʻi ka hopena ana o ke ana wela.
3 ʻAʻole hiki ke ana i ke kinoea, ka mahu a me nā mea hoʻolaha ʻē aʻe.
4 Inā lōʻihi ka hana ʻana o ka electrode ana, aia paha ka scaling, hiki ke ana ʻia ma hope o ka hoʻomaʻemaʻe ʻana.
5 No ka mea viscosity kiʻekiʻe a me ka paʻa-wai ʻelua-phase medium, pono e hoʻohana i ke alapine kiʻekiʻe excitation, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa magnetic pololei.
6 Ma muli o ka palena o ke kumu o ka ʻōnaehana sensor, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o nā huahana caliber nui, e hopena i ka piʻi ʻana o ka caliber huahana a me ke kumukūʻai.
7 Ma muli o kāna mau palena kumu, pono e hoʻoikaika ʻia ka coil sensor sensor e hoʻohua ai i kahi māla magnetic, a ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka mana, ʻaʻole kūpono ia no ka hāʻawi ʻana i ka mana pākahi.

1. ʻOi aku ka pololei o ka mīkini kahe mākēneki ma mua o ko ka ultrasonic flowmeter.
2. Hoʻopili ʻia ke kumukūʻai electromagnetic flowmeter e nā anawaena paipu, akā no ka hoʻopili ʻana i ka mika kahe kani ultrasonic, ʻaʻole pili kona kumukūʻai me ke anawaena paipu.
3. Magentic kahe ana mika 'aʻohe pipili ma ke 'ano, ultrsonic kahe ana mika ke koho no ka clamp ma, hiki ke hoʻokō 'ole pili wai kahe mika.
4. Ultrasonic kahe mika hiki ke hana me non conductive wai, e like me ka wai maemae.Hiki i ka mīkini kahe electromagnetic ke ana i ka wai conductive.
5. ʻAʻole hiki ke ana i ka mika kahe electromagnetic i nā wai wela kiʻekiʻe loa, akā ʻoi aku ka maikaʻi o ka mīkini kahe kani ultrasonic i nā wai wela kiʻekiʻe.
