1).Hoʻokomo pūnaewele a hoʻopaʻa wela, ʻaʻohe ʻoki paipu a hoʻopau ʻia paha.
2).He maʻalahi ka hoʻokomo ʻana i nā mea ʻike clamp-on, hiki ke hoʻokomo ʻia ma ke kaomi paipu kiʻekiʻe.
3).ʻAʻole pili pono ka pipili ma luna o ka mea ʻike flowmeter me ke ana.Hiki iā ia ke ana i nā ʻano mea maʻamau a me nā mea ʻawaʻawa, lepo, granular, ikaika corrosive, wai viscous.
4).ʻAʻohe ʻāpana neʻe o ka mea ʻike, ʻaʻohe mea pale i ka wai, ʻaʻohe poho puʻe, he mika kahe e mālama ai i ka ikehu.
5).ʻO ke kumu hana he transit-time.ʻAʻole i kaupalena ʻia e ka nui o ka paipu, a ʻo kona kumukūʻai ke kumu me ka nānā ʻole i ke anawaena paipu, no laila e hoʻohālikelike ʻia me nā ʻano flowmeters ʻē aʻe, ʻike ʻia ke kumu kūʻai o ka ultrasonic flowmeter.
a. Hoʻohālikelike me ka electromagnetic flowmeter:hiki ke kau i ka ultrasonic flowmeter ma ka ili o waho o ka paipu no ka ana ana o ka wai.hiki ke ana i ka haʻahaʻa kahe kahe, hiki ke hoʻokomo i ka pūnaewele, nui ke anawaena paipu i ke kumu kūʻai o ka mana maikaʻi loa;Hiki i nā mīkini kahe kani kani ke ana i nā wai non-conductive, e like me ka aila, ka wai ultrapure, etc.
b. Hoʻohālikelike ʻia me ka mīkini kahe kahe ʻokoʻa:ʻO ka mīkini kahe kani ultrasonic ʻaʻole he hōʻailona hoʻouna hewa (ʻo ke kumu nui o ka hāʻule ʻana o ke kaomi ʻokoʻa), a hiki i ka mīkini kahe kani ultrasonic ke ana i ka wai ʻawaʻawa a me ka wai corrosive, me ke ana kiʻekiʻe, ʻaʻohe poho puʻe, hoʻonohonoho maʻalahi, mālama maʻalahi, etc.
c. Hoʻohālikelike ʻia me Coriolis mass flowmeter:ʻAʻole hiki ke ana ʻia ka wai lepo, ʻo ia me ka paʻa ʻole maikaʻi (Coriolis mass flowmeter zero point he maʻalahi ke neʻe), ʻaʻole i hoʻopilikia ʻia nā mīkini kahe kani ultrasonic e ke kau ʻana i ke koʻikoʻi, ʻaʻole. kaupalena ʻia e ka paipu anawaena (Coriolis mass flow meter ≤ DN300), akā ʻoi aku ka kiʻekiʻe o ka pololei o ka mīkini kahe ʻana o Coriolis ma mua o ka mīkini kahe kani ultrasonic.
d. Hoʻohālikelike ʻia me ka vortex flowmeter:Hiki i ka mīkini kani kani kani ke ana i ka haʻahaʻa kahe, ʻaʻole i kaupalena ʻia e ka paipu anawaena (vortex street ≤DN300), maikaʻi seismic kū'ē, lepo viscous corrosive ana wai, hiki ke hoʻouka online, ke ana pololei kiʻekiʻe.
