1) Pono ka paipu electromagnetic flowmeter i ʻoi aku ka pōkole ma mua o ka ultrasonic flowmeter.Electromagnetic flowmeter hoʻokomo kahua hiki hou pololei paipu, no laila e hoʻohālikelike i ke kahua, e hoʻolohe i ke kūlana o ke ana inā hiki ke hoʻokō i nā koi o ka paipu pololei ultrasonic flowmeter, inā ʻaʻole e hoʻokō i ka paipu pololei e kokoke e koho i conforms i ke kūlana o ʻo ke ana ultrasonic flowmeter, hoʻohālikelike ʻaʻole pololei nā hopena.
2) E nānā inā hoʻokō ke kūlana hoʻokomo o ka flowmeter electromagnetic i nā koi o ke kahe wai (e like me ka conductivity o ka wai, inā paha ka hoʻokomo ʻana ma ke kūlana haʻahaʻa o ka pipeline, inā paha e hōʻiliʻili nā ʻōpala, etc.).Inā ʻaʻole, pono e noi ʻia i ka mea hoʻohana ʻo ia paha ke kumu o ka pilikia.
3) He mea hana maikaʻi ʻo Electromagnetic flowmeter e ana i ke kahe o ka wai conductive.He kiʻekiʻe loa ka pololei o kāna ana ʻana, ma ke ʻano he 0.5%, a ʻoi aku ka maikaʻi o ka hiki ʻana i 0.2%.I ka manawa like, pono e uku ʻia i ka mea hana o ka electromagnetic flowmeter.Inā hoʻokomo ʻia ka huahana brand me ka hewa ʻole a hoʻokō ka conductivity wai i nā koi, pono e noʻonoʻo pono ʻia ka waiwai o ke ana, ʻoiai no nā mea hana non-mainstream, e like me ke kūpaʻa waiwai electromagnetic a me ka nui o ka hewa, hiki iā ʻoe ke wiwo ʻole i ke kanalua.
4) E hoʻomaopopo i ke kūlana waiwai o ka pipeline, inā he lining, scaling a me nā mea ʻē aʻe a me nā ʻāpana pili o ka pipeline mai ka mea hoʻohana.E hoʻolalelale i ka pipeline i ka wā e hoʻokomo ai i ka mea kani ultrasonic, a koho i ke ala Z no ke ana a me ka hoʻohālikelike ʻana i ka hiki.
5) ʻO ka wai e hiki ke ana ʻia e ka ultrasonic flowmeter ʻaʻole i pili i ka conductivity.Inā paʻa ka waiwai kani ultrasonic a ʻo ka waiwai electromagnetic ʻaʻole paʻa i ka wā hoʻohālikelike, hōʻike ia i ka conductivity o ke kino kahe e ana ʻia i loko o ka mokuʻāina palena o ka index, ma mua o ke kumu o ka wai i loko o ke kinoea, a me ka waiwai o ka ultrasonic ʻoiaʻiʻo ka flowmeter.Inā paʻa ʻole nā mea ʻelua i ka manawa like, ʻoi aku ka nui o ka hiki ʻana o nā ʻōpū.
6) ʻO nā koi electromagnetic flowmeter e ana ʻia ka wai e like me ka honua, inā ʻaʻole e loaʻa kahi ana interference ikaika, no laila ke hewa ʻole a i ʻole ke kumu ʻino (ʻoi aku ka paʻakikī a me nā koi koʻikoʻi o ka grounding electromagnetic), aia nā pilikia. , pono e nānā i ke kūlana kahua.Ke hoʻohālikelike ʻia me ka ultrasonic flowmeter, ʻaʻohe koi pono no ka wai.Inā nīnau ʻia ke kumu, pololei ka waiwai o ka ultrasonic flowmeter.
7) Inā loaʻa nā pā uila a me nā mākaʻikaʻi ma kahi kokoke, ʻoi aku ka liʻiliʻi o ka mana o ka flowmeter ultrasonic ma mua o ka electromagnetic flowmeter, a ʻoi aku ka hilinaʻi o ka waiwai hōʻike ultrasonic ma mua o ka electromagnetic flowmeter.
8) Inā he kumu kani keʻakeʻa i loko o ka pipeline (e like me ke kani i hana ʻia e ka nui o ke kaomi ʻokoʻa hoʻoponopono valve), ʻoi aku ka nui o ka mana ma ka ultrasonic ma mua o ka electromagnetic, a ʻoi aku ka hilinaʻi o ka waiwai hōʻike electromagnetic ma mua o kēlā. o ke kani ultrasonic.
