Ngā Take e Pā Ana ki te Tika o te Pānui me te Tika Katoa o ngā Mita Rere Ultrasonic

Ngā Take e Pā Ana ki te Tika o te Pānui me te Tika Katoa o ngā Mita Rere Ultrasonic

I. Ngā Āhuatanga Wai

1. Te ōritetanga o te tohatoha tere rere

• Tikanga Pānga: Ka tatauhia e ngā mita rere oro-oro mā te ine i te rerekētanga wā (tikanga rerekētanga-wā) te nekehanga auau rānei (tikanga Doppler) o ngā ngaru oro e horapa ana i roto i te wai. E whakawhirinaki ana tēnei ki te whakaaro he pumau, he ōrite hoki te tohatoha tere wai i roto i te wāhanga whakawhiti ine.
• Ngā Pānga Motuhake: Mena he koretake te tohatoha tere (hei tauira, he awhiowhio, he rere whakarara rānei), kāore e taea e te tere i te ara horapa o te ngaru oro te whakaatu i te tere toharite tūturu, ka puta he rerekētanga i waenga i te uara i inehia me te uara tuturu.
  • Mō te Tika o te Pānui: Nā te mea e whakawhirinaki ana te tika o te pānui ki te uara ine tuturu, ka whakanuia tika ngā hapa ine e te tohatoha tere kore taurite (ina koa i ngā reiti rere iti, ina nui ake te ōwehenga pekapeka).
  • Mō te Tika Tauine Katoa: Ahakoa ko te paearu hapa he tauine katoa, ka puta tonu te rerekētanga o te uara ine mai i te uara pono nā te raruraru tere. Heoi, ki te tata te tere rere tuturu ki te tauine katoa, ka taea te whakahaere i te pānga o te hapa tuturu ki te tika tauine katoa; ki te iti te tere rere, ka "hunaia" pea te ōwehenga o te hapa tuturu ki te tauine katoa, engari kua piki ake te hapa whanaunga tuturu.

2. Ngā Āhuatanga Ā-tinana o te Wai

• Te Pāmahana me te Pēhanga: Ka pāngia te tere o te oro e ngā panonitanga o te pāmahana wai (ka piki te tere o te oro i te pāmahana), ā, ka rerekē pea te āhua o te paipa i te pēhanga nui, ka whakarerekē i te ara horapa o te ngaru oro. Mēnā kāore te mita e whai mana mō te pāmahana/pēhanga, ka puta he hapa pūnaha.
• Te Matatini me te Ihirangi Parakore/Mirumiru: Ka taea e ngā wai matatini teitei te whakaroa i te tere, ka taea e ngā mirumiru, e ngā matūriki totoka rānei te marara, te mimiti rānei i ngā ngaru oro, ka arahi ki te ngoikore o te tohu, te wā horapa kore pumau, te ngaronga rānei o te tohu, ka whakaiti tika i te tika o te ine.
• Momo Wai: Hei tauira, he rerekē rawa te tere o te oro o ngā hau me ngā wai. Ki te kore te mita e whakatikatikaina mō te momo wai motuhake, ka pāngia nuitia ngā tika e rua.

II. Ngā Āhuatanga o te Tāutanga

1. Tūnga me te Tikanga Tāutanga Pūoko

• Te Kōwhiringa o te Wāhi Tāutanga: Me tāuta ngā pūoko ki ngā wāhanga paipa tika. Mena he pūtake pokanoa kei runga (pērā i ngā tuke, ngā takirere, ngā papu rānei) ā, kāore i te rawaka ngā wāhanga paipa tika kua rāhuitia (ko te tikanga me nui ake i te 10 ngā wā o te whānui o te paipa ki runga, me te 5 ngā wā ki raro), ka kore e pai te tohatoha tere (e ai ki te kōrero i mua ake nei).
• Ngā Hapa o te Tikanga Tāutanga: Mā te rerekētanga o te mokowā o te pūoko, te koretake o ngā koki honga (kāore i te rite ki te tuaka paipa), te kore ōrite rānei o te whakamahinga o te hononga (mō ngā pūoko whakapiri) ka puta he hapa i te ine i te roa, i te koki rānei o te ara horapa o te ngaru oro, ka puta he rerekētanga pumau.

2. Ngā Āhuatanga o ngā Paipa

• Hototahi ki te Diameter o te Paipa: Mena kāore te diameter o te paipa ingoa o te mita rere e ōrite ki te diameter tuturu o te paipa (kāore rānei e mahia he whakatikatika diameter), ka puta he hapa i roto i te tātai tahuritanga tere-rere (rere = tere × horahanga whakawhiti-wāhanga), ka pā tika ki te uara ine.
• Ngā Rauemi Paipa me te Āhua o te Pakitara o Roto: Ka pā te rauemi paipa (hei tauira, te konganuku, te kirihou) ki te urunga o ngā ngaru oro (he iti ake te whakaiti i te ngaru oro o ngā paipa kirihou, engari me whai whakaaro ki te matotoru o te pakitara o ngā paipa konganuku); ka huri te tauine, te waikura, te taratara rānei o te pakitara o roto i te ara whakaata/whakaata o te ngaru oro, ka puta ai te whakapōturitanga o te tohu.

III. Ngā Take Mahi Taputapu

1. Mahi a te Pūoko

• Auautanga me te Tairongo: Me ōrite te auautanga mahi o te pūoko ki ngā āhuatanga wai (hei tauira, me whakamahi auautanga iti mō ngā wai matotoru nui hei whakaiti i te ngoikore); ki te kore e rawaka te tairongo, ka kore e taea te tautuhi i ngā tohu ngoikore, ka whakaiti i te pumau o te ine.
• Te Pūkenga Ārai-Waewae Tohu: Mena kāore i te rawaka te āheinga tātari o te pūoko mō ngā tohu ngaru oro, ka ngāwari te wawaea e te wiri paipa me te haruru o te aueue o te wai, ka hua ake ngā rerekētanga o ngā uara ine me te pikinga o ngā hapa matapōkere.

2. Ngā Taputapu me ngā Arorau Mita

• Te Pūkenga Tukatuka Tohu: Ko te rerekētanga wā o te horapa o te ngaru oro kei te taumata nanohekona. Mena kāore i te rawaka te tika o te wā o te mita (hei tauira, te tere tauira, te pumau o te karaka), mena rānei he rerekētanga i roto i te ara iahiko whakanui/tātari tohu, ka puta he hapa pūnaha.
• Arotautanga Pūmanawa: Ka taea e ngā pūnaha tukatuka tohu matihiko matatau (hei tauira, te tātari urutau, te hangarau ine maha-hongere) te whakaiti i te pokanoa haruru me te whakatika i ngā hapa i puta mai i te tohatoha tere kore taurite, ka whakapai ake i te tika o te pānui; i tetahi atu taha, ka whakanuia e ngā pūnaha māmā ngā peka ine.

IV. Ngā Take Whakararuraru Taiao

1. Te Haruru me te Wiri o Waho

• Ka taea e te wiri ā-ringa i ngā wāhi ahumahi (hei tauira, mai i ngā papu, i ngā motuka rānei) te whakaneke i te pūoko, te haruru rānei o te paipa, ka whakarerekē i te ara horapa o te ngaru oro; ka taea e te haruru kaha (hei tauira, ngā tohu hiko auau teitei, te pokanoa oro) te huna i ngā tohu whai hua, ka hua ake he peke uara ine.

2. Te Whakararuraru Hikohiko (EMI)

V. Ngā Tauwehe Tautuhinga me te Whakamātautau

1. Te Whaitake o te Tautuhinga Awhe

• Mō te Tika Tauine Katoa: Mena ka whakatakotoria te awhe tauine katoa he nui rawa (he nui rawa atu i te tere rere mōrahi tūturu), ka noho tonu te tere rere tūturu ki te awhe iti mō te wā roa. Ka tino piki ake te hapa tino o te tika tauine katoa (±b% × tauine katoa) i runga i te ōwehenga ki te tere rere iti (hei tauira, tauine katoa = 1000 m³/h, tere rere tūturu = 100 m³/h, ±1% hapa tauine katoa = ±10 m³/h, me te hapa whanaunga o ±10%).
• Mō te Tika o te Pānui: Mā te whakatakoto i te awhe iti rawa ka nui rawa te awhe i ngā tere rere teitei, ka hua ake he uara ine kua kī; kāore te whakatakoto i te nui rawa e pā tika ki te hapa whanaunga o te tika o te pānui (nā te mea e hono ana te hapa ki te uara tuturu), engari kāore pea te kaha o te tohu e ranea i ngā tere rere iti, ka nui ake ngā hapa.

2. Te Kounga Whakamātautau

• Ko te whakatikatika te tukanga matua mō te whakatau i te "rerekētanga i waenga i ngā uara ine me ngā uara pono." Mena kāore i te rawaka te tika o te taputapu whakatikatika, kāore rānei te tukanga whakatikatika i te paerewa (hei tauira, kāore he whakatikatika maha-ira puta noa i te awhe katoa), ka piki ake te hapa pūnaha o te mita, ā, ka rerekē te tika o te pānui me te tika o te tauine katoa i ō rāua uara ingoa.

VI. Whakarāpopototanga

• Ngā Take Matua o te Pūtake: Ko te tohatoha tere wai, te whakapūmautanga o te tāutanga, te mahi a te pūoko, te wawaotanga taiao, me te kounga o te whakatikatika he take matua e pā ana ki te tika o ngā mea e rua, e whakatau tika ana i te rerekētanga i waenga i ngā uara ine me ngā uara pono.
• Ngā Pānga Rerekē: He nui ake te pānga o te tautuhinga awhe ki te tika o te tauine katoa (te whakanui hapa whanaunga i ngā tere rere iti); i tētahi atu ringa, ka whakawhirinaki te tika o te pānui ki te kaha o te pūnaha tukatuka tohu ki te hopu i ngā tohu rere iti me te whakatika i ngā hapa i puta mai i te tohatoha tere kore taurite.
