Ngā Mita Wai o te Whare

I. Te Whakamāramatanga me te Tūnga Mahi

II. Ngā Momo Matua me ngā Āhuatanga Hangarau

1. Mita Wai Ā-ringa

• Mātāpono: Ka hurihia te impeller e te rere o te wai, ā, ka hurihia he kaute e te tuku taputapu hei whakaatu i ngā pānui. Ko ngā momo noa ko te tāpine (diameter iti) me te poroporo (diameter nui).
• Ngā Āhuatanga:
  • He iti te utu, he māmā te hanganga, he ngāwari te tiaki;
  • Akomanga tika Akomanga 2 (±2%), ko te ōwehenga whakahurihuri i te nuinga o te wā ko 30:1–50:1;
  • Kāore he mahi atamai, me pānui ā-ringa; ka pāngia te tika mō te wā roa e te kakahu miihini.

2. Mita Wai Kāri IC Atamai

• Mātāpono: He inenga ā-ringa kua whakauruhia ki tētahi waeine utu-mua kāri IC. Ka taea e ngā kaiwhakamahi te utu anō hei whakatuwhera i te takirere mā te swipe kāri, me te whakaweto aunoa ina iti te toenga.
• Ngā Āhuatanga:
  • Tautoko i te whakahaere i ngā utunga o mua hei whakaiti i ngā tautohe mō ngā nama tārewa;
  • Pūhiko (3–5 tau te roa o te ora), akomanga tiaki IP65;
  • Ka tautoko ētahi tauira i te rokiroki raraunga engari he iti noa iho ngā āheinga whakawhitiwhiti kōrero mamao.

3. Mita Wai Pānui Mamao

• Mātāpono: Te ine ā-ringa me te waeine kohikohi hiko, e tuku raraunga ana mā ngā hongere waea (RS485, M-Bus) ahokore rānei (NB-IoT, LoRa, ZigBee).
• Ngā Āhuatanga:
  • Ka whakahohe i te pānui aunoa me te reiti angitu >99%;
  • Ka taea te hono atu ki te mana takirere (whakakā/whakaweto mamao) mō te utu wai taumata-maha;
  • Te tika noa o te karaehe 1.0, e tautoko ana i te aroturukitanga rere ā-rua (ētahi tauira).

4. Mita Wai Kāinga Ultrasonic

• Mātāpono: Ehara i te miihini, e whakamahi ana i te tikanga rerekētanga-wā ultrasonic mō te ine rere, kua whakauruhia ki ngā maramara atamai me ngā waeine whakawhitiwhiti kōrero.
• Ngā Āhuatanga:
  • He tino tika (±0.5%–1%), he ōwehenga hurihanga tae atu ki te 500:1, he pai mō te ine ine iti-rere;
  • Te roa o te ratonga ≥10 tau, kāore he tiaki;
  • E tautoko ana i te whakahaere mamao me te whai i ngā raraunga, engari he nui ake te utu
