Ngā Painga o ngā Mita Wai Ultrasonic ki te Whakatairite ki ngā Mita Wai Mīhini

I. Tātaritanga Painga Taipitopito

1. Te Tika o te Ine, Kāore he Hapa o te Whakamaunga Mīhini Ka ine ngā mita wai ultrasonic i runga i te rerekētanga wā, i te mātāpono Doppler rānei, kāore he wāhanga neke i roto. Ka whakakorea e rātou ngā take o te whakamau me te waikura o ngā wāhanga mīhini pēnei i ngā impeller me ngā taputapu, ka pupuri i te tika o te ine pumau mō te wā roa (te akomanga tika tae atu ki te ±0.5%FS, me te ±0.2%FS mō ētahi tauira tino tika). Hei tāpiri, ka taea e rātou te hopu tika i ngā tere rere iti (te iti rawa o te rere tīmatanga tae atu ki te 0.01m/s), ka karo i te raruraru noa o te "iti o te tatau rere" i roto i ngā mita wai mīhini, e tutuki ana i ngā whakaritenga ine tika mō te whakataunga hokohoko. He rerekē, ka whakawhirinaki ngā mita wai mīhini ki te hurihanga o te impeller mō te ine. He ngāwari te whakamau me te tauine o te impeller nā te poke o te wai i muri i te whakamahinga roa, ka hua ake te hekenga āta o te tika me ngā hapa nui i ngā tere rere iti, me te whakatikatika me te whakakapinga auau.
2. Roa Ake te Ora Ratonga, Tino Iti te Utu TiakiKo ngā wāhanga matua o ngā mita wai ultrasonic ko ngā pūoko me ngā wāhanga hiko, he hoahoa hiri me te ātete wai (akomanga tiaki tae atu ki te IP68). Ko te nuinga o te tinana mita he mea hanga ki ngā rauemi ātete-waikura pērā i te maitai kore waikura 316L me ngā kirihou hangarau. I raro i ngā āhuatanga mahi noa, ka taea e te roanga ratonga te eke ki te 10 – 15 tau. Kāore e hiahiatia he wetewete me te horoi auau, ā, he tirotiro noa i ngā wāhanga hiko e hiahiatia ana, e tino whakaiti ana i ngā utu whakahaere me te tiaki mō ngā kamupene tuku wai.Heoi, ko ngā mita wai mīhini he tino pāngia e te kounga o te wai, me ngā raruraru nui o te kakahu me te aukati. Ko te roanga ratonga he 5 – 8 tau noa iho. Me wetewete auau te mita mō te whakatikatika me te whakakapinga wāhanga, e uru ana ki ngā tukanga tiaki uaua me ngā utu nui.
3. Teitei o te Mātauranga, Te Urutau ki te Hanganga Tiaki Wai Atamai. Ka tautokohia e ngā mita wai ultrasonic te whānui atamai. Ka taea e rātou te whakauru i ngā kawa whakawhitiwhiti kōrero pēnei i a MODBUS, M-BUS me LoRa hei whakatutuki i te kohikohinga raraunga mamao, te aroturuki wā-tūturu me ngā whakaoho ohorere (hei tauira, te turuturu wai me ngā whakamaharatanga tapahi wai). Ka taea hoki te whakauru ki ngā kōwae utu-mua me ngā takirere mana mamao, hei whakatutuki i ngā hiahia o ngā kaupapa wai atamai o tāwāhi. Ka taea e ētahi tauira te aroturuki i ngā tawhā maha tae atu ki te pāmahana wai me te pēhanga wai i te wā kotahi. Ko ngā mita wai miihini e whakawhirinaki ana ki te tatau miihini, e tautoko ana i te pānui mita ā-ringa i te papaanga anake, ā, kāore e taea te whakatutuki i te tuku raraunga mamao. He uaua te whakawhiti atamai, ā, he koretake te pānui mita ā-ringa, he ngāwari hoki te hapa, kāore e rite ki te ia o te whakahaere wai o ēnei rā.
4. He iti te ātete ki te rere o te wai, te tiaki pūngao me te urutau ki te kounga wai uaua. Mā te hoahoa o te awa rere maeneene, me te kore he wāhanga ārai pērā i ngā impeller, tata kore he mate pēhanga o ngā mita wai ultrasonic, ka taea te whakaiti i te whakapaunga pūngao o ngā paipa tuku wai. I taua wā, kāore e pāngia e te paru me ngā totoka iri i roto i te wai, e pai ai mō ngā āhuatanga kounga wai uaua pērā i te paru me te wai whakahoki. He rerekē, he ngāwari ngā mita wai miihini ki te hē nā te aukati i te impeller nā te poke. He mate pēhanga ngā mita wai miihini nā te mea ka āraihia te rere o te wai e ngā impeller me ētahi atu wāhanga. He nui ngā whakaritenga mō te kounga wai (me wai mārama, kāore he poke) nā te mea ka taea e ngā poke i roto i te wai te whakararu i te impeller.
5. Kaha te Ārai-Waewae, Pūmau te Mahi Ine Ka taea e ngā mita wai ultrasonic te whakamahi i tētahi hoahoa kore-aukume hei ārai i te wawaenga mai i ngā papa aukume kaha o waho, hei karo i te ine hē o ngā mita wai miihini i puta mai i te wawaenga aukume. Ko ētahi tauira he mahi tātari tohu, e āhei ai te mahi pumau ahakoa i roto i ngā taiao ahumahi uaua. Ka taea e te wawaenga papa aukume te pā tika ki te hurihanga o ngā impeller i roto i ngā mita wai miihini, ka puta he hapa ine, he mutu rānei te mita, ka hua ake he ngoikore te āheinga ārai-wawae.
6. Tāutanga Ngāwari, Te Urutau ki Ētahi Atu Horopaki Ka tautokohia e ngā mita wai ultrasonic te tāutanga whakapae, poutū me te piko, me ngā whakaritenga koretake mō ngā wāhanga paipa tika o runga me raro (ko ētahi tauira e hiahia ana kia 3D te runga me te 1D te raro). He pai mō ngā taiao tāutanga uaua pēnei i ngā wāhi whaiti me ngā puna o raro whenua. Ka kapi i te whānuitanga o ngā karāhe (DN15 – DN600), ka taea e rātou te whakatutuki i ngā hiahia o ngā horopaki rerekē tae atu ki ngā whare noho, ngā whare arumoni me ngā whare ahumahi. Ko ngā mita wai mīhini he tikanga he ahunga tāutanga pumau (te nuinga he tāutanga whakapae) me ngā whakaritenga tino pakari mō ngā wāhanga paipa tika (te nuinga he 10D te runga me te 5D te raro). He iti ngā karāhe, ā, he ngoikore te urutau ki ngā horopaki rere nui.
