I tēnei wā e tino hira ana te tiaki wai, te whai huatanga o te mahi, me te whakahaere raraunga—mai i te tuku wai ā-tāone ki te whakamahinga ahumahi—kua puta ake ngā mita wai ultrasonic hei huarahi pai ake i ngā mita wai mīhini tuku iho. Kāore i rite ki ngā mita tuku iho e whakawhirinaki ana ki ngā wāhanga neke (pērā i ngā impeller, piston rānei) e ngāwari ana ki te pakaru, ki te ārai, ki te hē rānei i roto i te wā, ka whakamahia e ngā mita wai ultrasonic ngā ngaru oro auau teitei hei ine i te rere o te wai me te kore e pā atu ki te tinana. Ehara i te mea ka tukuna e tēnei hangarau auaha te tino tika engari ka whakaitihia hoki ngā hiahia tiaki, ka roa ake te roa o te ratonga, ā, ka taea te aroturuki atamai—ka waiho hei tūāpapa mō ngā pūnaha whakahaere wai hou. Mō ngā ratonga, ngā pakihi, tae noa ki ngā whare noho, ehara ngā mita wai ultrasonic i te taputapu ine noa iho; he mea whakakorikori mō te whakamahinga wai pumau me ngā mahi utu-whai hua.
Ko te painga matua o ngā mita wai ultrasonic kei roto i tōna kaupapa mahi kore-mīhini, e whakakore ana i ngā hapa o ngā hoahoa tuku iho. Anei te āhua o tā rātou mahi: Ko te nuinga o ngā mita wai ultrasonic e whakamahi ana i te tikanga "wā-haere", e rua ngā whakawhiti (kotahi e tuku ana, ko tētahi e whiwhi ana) e whakairihia ana ki te pakitara o roto, o waho rānei o te paipa. Ka tukuna e te kaituku ngaru ultrasonic mā roto i te wai i te ahunga o te rere me te taha ki waho. Ka tere ake te wai e rere ana i roto i te paipa i ngā ngaru e haere tahi ana me te ia, ā, ka whakaroa i te hunga e neke ana ki waho—ka hangaia he "rerekētanga wā" ine i waenga i ngā tohu e rua. Ka tatau te tukatuka o te mita i te tere rere me te rōrahi katoa mā te tātari i tēnei rerekētanga wā, me te kore he wāhanga neke hei taunekeneke ki te paru, ki ngā kohuke, ki ngā paru rānei i roto i te wai. Ka whakatauhia e tēnei hoahoa ngā āhuatanga mamae nui e rua o ngā mita mīhini: tuatahi, ka karohia te aukati mai i te onepu, te waikura, te mea rauropi rānei (he take noa i roto i ngā pūnaha wai tawhito), e hiahia ana kia wetewetehia me te horoi pinepine. Tuarua, ka whakakorea te kakahu mai i te waku—he maha ngā wā ka ngaro te tika o ngā mita mīhini i muri i te 5–7 tau, ko ngā tauira ultrasonic ia e mau tonu ana te tika mō te tekau tau neke atu rānei. Mō tētahi ratonga ā-rohe, ko te tikanga he iti ake ngā waeatanga ratonga, he iti ake ngā utu mahi, ā, he rite tonu te tika o ngā utu mō ngā mano tini o ngā kiritaki.
Haunga te pono, ka tukuna e ngā mita wai ultrasonic te tino tika me te mahi atamai e whakatairanga ana i te whai huatanga o te wai. Ko te whānuitanga tika o ngā mita miihini tuku iho he ±2% ki te ±5%, engari he maha ngā tauira ultrasonic ka eke ki te ±1%, pai ake rānei—ahakoa he tino iti te rere (pēnei i te turuturu puhoi). He mea nui tēnei aro ki te kimi turuturu: i roto i ngā whare noho, ka kore pea e kitea he turuturu iti (tae atu ki te 1 rita ia hāora) e te mita miihini, engari ka taea e te mita ultrasonic te whai i a ia, ka whakatūpato i ngā kaiwhakamahi ki te wai maumau me ngā kino pea o ngā taonga. Mō ngā whare ahumahi—pēnei i ngā whare hanga, i ngā hōtēra rānei—e whakamahi ana i ngā rahinga wai nui, ka arotau hoki tēnei tino tika i te whakamahinga: mā te aroturuki i ngā raraunga rere wā-tūturu, ka taea e ngā kaiwhakahaere te tautuhi i ngā koretake (hei tauira, te whakamahinga nui o te wai i roto i te raina whakaputa) me te whakatika i ngā tukanga hei whakaiti i te para. Heoi anō, ko te nuinga o ngā mita wai ultrasonic hou he "atamai" te whakahohenga: ka hono atu ki ngā tūāpapa IoT mā te ahokore (LoRaWAN, NB-IoT) me ngā whatunga waea rānei, ka taea ai te pānui mamao, te takiuru raraunga, me ngā whakatūpato aunoa. Hei tauira, ka taea e ngā kaunihera ā-rohe te whakakapi i te pānui mita ā-ringa (he mahi roa, he mahi nui) ki te aroturuki mamao, ka tapahia ngā utu whakahaere mā te 30% neke atu rānei. Ka taea hoki e rātou te whakamahi i ngā raraunga hei tātari i ngā tauira whakamahinga—te tautuhi i ngā wā tono nui hei whakatika i te pēhanga wai, hei kite rānei i te whakamahinga rerekē e tohu ana i te turuturu o te raina matua.
He tino pai hoki ngā mita wai ultrasonic mō te maha o ngā whakamahinga me te urutau ki te taiao, ā, he pai mō ngā tono kanorau. E wātea ana i roto i ngā rahi rerekē—mai i ngā tauira noho iti (½ inihi ki te 2 inihi) ki ngā paipa ahumahi nui (10 inihi, neke atu rānei)—ā, ka taea te whakahaere i ngā pāmahana wai rerekē (mai i te 0°C ki te 100°C) me ngā pēhanga. Kāore i rite ki ētahi atu mita matatau (pēnei i ngā mita hikohiko), ka mahi tahi rātou me te wai inu me ngā wai kore-arataki (hei tauira, te wai para kua tukatukahia), ka whakawhānui ake i tā rātou whakamahinga ki ngā pūnaha para, ki te whakamakuku rānei. Hei tāpiri, ko tā rātou hoahoa kore-whakauru (he maha ngā tauira ka taea te tāuta ki waho ki ngā paipa o nāianei) ka māmā ake te whakahou: mō ngā whare tawhito, mō ngā tāone rānei he hanganga tawhito, kāore he take ki te kati i te ratonga wai, ki te whakakapi rānei i ngā wāhanga paipa katoa hei whakapai ake i ngā mita. He mea nui tēnei ngāwari mō ngā rohe e whakahoutia ana te pūnaha wai—ka taea te whakamahi mārire me te kore e whakararuraru i ngā mahi o ia rā. Mō te rangatira whare arumoni, ko te tikanga o tēnei ko te whakapai ake ki te whakahaere wai atamai me te kore he hanganga utu nui, me te hauhake tonu i ngā painga o ngā pire wai iti me te whakapai ake i te pumau.
I te mea ka noho te korenga o te wai hei āwangawanga nui, ā, kei te piki haere te pēhanga o ngā ratonga ki te whakaiti i ngā para me ngā utu whakahaere, ka tū ngā mita wai ultrasonic hei otinga pumau, ā, he otinga mō te heke mai. Mā te hoahoa kore-mīhini ka whakarite i te pono mō te wā roa, mā te tika ka akiaki i te whai huatanga, ā, mā ngā āhuatanga atamai ka taea te whakatau kaupapa e ahu mai ana i ngā raraunga. Ahakoa e whakamahia ana hei utu tika i ngā kainoho, hei kimi i ngā turuturu i roto i te wheketere, hei whakapai ake rānei i te whakamakuku i roto i te hapori, ka whakaatu ēnei mita he nui atu i te mahi whakahaere noa iho te ine wai—ka taea te waiho hei taputapu hei tiaki i tētahi rauemi nui. Mō tētahi whakahaere e hiahia ana ki te whakahou i tana whakahaere wai, ehara ngā mita wai ultrasonic i te whakapai ake noa iho; he haumi ki te pumau, te whai huatanga, me te angitu whakahaere mō te wā roa. I roto i tētahi ao e whai tikanga ana ia pata, ko ngā mita wai ultrasonic te kaiārahi i te huarahi ki te whakamahi wai tika.
