Ngā Mita Wai Ultrasonic e Whakahaeretia ana e te Takirere

I. Te Whakamāramatanga me ngā Wāhanga Matua

• Wāhanga Ine Ultrasonic: Ka whakamahi i te mātāpono rerekētanga-wā, i te mātāpono Doppler rānei hei tatau i te rere mā te ine i te rerekētanga wā horapa ultrasonic i roto i ngā wai, kāore he wāhanga nekeneke miihini.
• Pūnaha Whakahaere Takirere Hiko: Ka whakauru i ngā takirere solenoid, ngā takirere pōro, ngā takirere pūrerehua rānei e peia ana e ngā motuka, e āhei ai te whakahaere whakaweto/whakaweto mamao, te whakahaere rere rānei.
• Kaiwhakahaere Maamaa: Ka whakauru i te tukatuka tohu, te rokiroki raraunga, me ngā kōwae whakawhitiwhiti kōrero (hei tauira, NB-IoT, LoRa) hei tautoko i te pānui mamao, te whakaoho rerekē, me ētahi atu.

II. Ngā Āhuatanga Hangarau Matua

1. Hoahoa Kore-Mīhini mō te Tika Teitei
   • Ka eke te tika ki te ±0.5%–±1% (i te awhe rere noa), me te ōwehenga hurihanga (Q3:Q1) neke atu i te 200:1, ka taea te hopu i ngā rere tae noa ki te 1L/h me te pumau mō te wā roa.
2. Mana Whakahaere Atamai me te Whakahaere Mamao
   • Tautoko ana i te mahi takirere mamao (hei tauira, te whakaweto mō te utunga kua tomuri, te whakatika hapa) me te whakahaere wā (hei tauira, te tuku wai wāhanga), te whakauru i ngā pūnaha whakahaere wai atamai.
3. He iti te whakamahinga hiko me te whānui o te urutau pāmahana
   • Mana tūtatari <100μW, te roa o te ora o te pākahiko lithium tae atu ki te 6–10 tau; kei waenga i te T50 (0.1–50°C) ki te T90 (0.1–90°C) ngā akomanga pāmahana, he pai mō ngā āhuatanga wai makariri/wera.
4. Ātete me te Hototahi ki te Whakararuraru
   • Kāore e pāngia e ngā papa aukume engari me tiaki mai i ngā mirumiru wai (>1mm) me ngā poke matūriki (me whakamahi tātari), he mea tino pai mō ngā puna wai ma.

III. Ngā horopaki tono

• Whakataunga Tauhokohoko me te Ine Tika: E whakamahia ana e ngā kamupene wai me ngā kaihoko ahumahi mō te ine me te utu tika.
• Te Whakahaere Wai Maamaa: Kua honoa ki ngā tūāpapa IoT mō te aroturukitanga rere i te wā tūturu, te whakatūpato turuturu, me te utu taumata.
• Ngā Tikanga Mahi Motuhake: Te tuku wai mō ngā whare teitei, ngā pūnaha hauhautanga (ātete ki te wiri), me te ine i te whare (e pā ana ki te iti o te rere).

IV. Ngā Painga me ngā Here

• Ngā Painga:
  • Kāore he wāhanga mīhini, he iti te utu tiaki, he roa te ora ratonga ≥10 tau;
  • Tautoko ana i te ine rere ā-rua (te tautuhi whakamua/whakamuri) mō ngā whatunga paipa uaua;
  • E tutuki ana i ngā raraunga ka taea te whai i ngā whakaritenga whakahaere mōhiohio wai.
• Ngā Here:
  • e 2–3 ngā wā teitei ake te utu i ngā mita wai ā-ringa;
  • Ngā whakaritenga tāutanga tino pakari (ngā wāhanga paipa tika, te karo i te wiri);
  • Me tukatuka i mua mō te wai pōuri, te nui rawa rānei o ngā mirumiru.
