I. Ngā Wāhanga Matua me ā Rātou Tūranga

1. Ngā pūoko rere ultrasonic e piri ana: He kawenga mō te ine i te tere rere o te wai i roto i te paipa. Ka whakairihia ki waho ki te pakitara o waho o te paipa tuku (whakahoki rānei) me te kore e pa ki te wai.
2. Ngā pūoko pāmahana: He rite tonu ki te rua o ngā pūoko ātete konukawata tino tika (hei tauira, PT1000 me te tika o te ±0.1℃), e tāutahia ana ki ngā paipa tuku me ngā paipa whakahoki hei aroturuki i te pāmahana wai tuku (T1​) me te pāmahana wai whakahoki (T2​) i te wā tūturu.
3. Kaihautū (tātaitai): Ka whiwhi i ngā tohu rere me te pāmahana, ka tatau i te wera mā te whakamahi i ngā rauropi kua hangaia, ā, ka whakahaere i te whakaaturanga raraunga, te rokiroki, te tuku rānei.

II. Ngā Hipanga Mahi Taipitopito

1. Ine Rere: Te Hopu i te Tere Rere mā te Tikanga Rerekētanga Wā Ultrasonic

• Tāutanga Pūoko: E rua ngā whakawhiti orooro (te tuku me te kaiwhiwhi) kua whakapirihia kia ōrite ki te pakitara paipa o waho mā te whakamahi i ngā rawhi, ka hangaia he ara horapa oro e rua—kotahi i te ahunga rere o te wai (kei raro) me tetahi ki te taha (kei runga).
• Te Tuku me te Whiwhi Tohu: Ka tukuna ngā tohu ultrasonic e te tuku i ngā taha whakararo me ngā taha whakarunga. I te horapa o ngā ngaru oro i roto i te wai, ka pāngia te tere o te wai e te tere o te wai: ka "kawea" ngā tohu whakararo e te rere, ka poto ake te wā haere; ka "ātetehia" ngā tohu whakarunga, ka roa ake te wā haere.
• Te Tatau Tere me te Rere: Ka ine te kaihautū i te rerekētanga wā (Δt) ka tatau i te tere rere inamata (v) mā te whakamahi i ngā tawhā pēnei i te diameter o te paipa me te rauemi. Kātahi ka hurihia tēnei tere ki te tere rere rōrahi inamata (qv​) ā, hei whakamutunga, ki te tere rere papatipu (qm​) mā te whakamahi i te kiato wai.

2. Te Ine i te Rerekētanga o te Pāmahana: Te Hopu i te Rerekētanga Pūngao i waenganui i te Wai Tuku me te Wai Hoki

• Te pāmahana wai tuku (T1): E tohu ana i te pāmahana tīmatanga o te wai e tomo ana ki te pūnaha whakawhiti wera (he nui ake te pūngao e kawe ana).
• Te pāmahana wai whakahoki (T2): E tohu ana i te pāmahana o te wai e puta ana i te pūnaha i muri i te whakawhiti wera (me te pūngao kua whakaitihia, nō reira he iti iho te pāmahana).
• Tātaitanga Rerekētanga Pāmahana: Ka tatau tonu te kaihautū i te rerekētanga (ΔT=T1​−T2​). Ko te rerekētanga pāmahana nui ake e tohu ana i te nui ake o te wera e whakawhitia ana i ia wā.

3. Tātaitanga Wera: Te Kohikohi i te Wera Katoa i runga i ngā Tātai Thermodynamic

• Ko Q te wera kua kohia (wāhanga: kWh, GJ rānei);
• ko qm te tere rere o te papatipu inamata (kg/h);
• Ko te cp​ te kaha wera motuhake o te wai i te pēhanga pumau (mō te wai, i te nuinga o te wā);
• Ko te ΔT te rerekētanga pāmahana i waenga i te wai tuku me te wai whakahoki (℃);
• Ko te tohu whakauru e tohu ana i te kohikohinga i roto i te wā (t), arā, te wera katoa i pau mai i te tīmatanga o te ine ki te wā o nāianei.
