Ngā Painga o ngā Mita Wai Hikohiko

1. Teitei o te Tika o te Ine

• E whakahaerehia ana i runga i te ture a Faraday mō te whakapūngao hikohiko, ina rere te wai kawe i roto i te papa aukume i hangaia e te mita, ka puta he kaha hikohiko i whakaohohia e rite ana ki te tere rere. Ka taea e ngā tauira matatau te whakatutuki i te tika ine tae atu ki te ±0.2%, neke atu rānei. He rerekē, ka pāngia ngā mita wai ultrasonic e ngā āhuatanga pēnei i te pāmahana wai, te pēhanga, ngā mirumiru hau, me ngā matūriki iri, me te tika i te nuinga o te wā i roto i te awhe ±0.5% – ±1%. Nō reira, he pai ake ngā mita wai hikohiko mō ngā horopaki me ngā whakaritenga ine rere tino tika.​

2. Te Pūmautanga Pai i raro i ngā Āhuatanga Uaua

• Kāore te mātāpono ine o ngā mita wai hikohiko e pāngia nuitia e te matotoru o te wai, e ngā panonitanga kiato i roto i tētahi awhe, e te hanganga rānei o te wai (mēnā he kawe hiko). I roto i ngā pūnaha wai ahumahi, ahakoa ka rerekē te kounga o te wai nā te tāpiri o ngā matū, te noho mai rānei o te iti o ngā poke, ka taea tonu e ia te whakarato i ngā pānui pumau. Heoi, ina rerekē ngā āhuatanga pēnei i te pāmahana wai, ka ngāwari te tika o te ine o ngā mita wai ultrasonic ki te rerekē haere. Nā te mea ka pā te pāmahana wai ki te tere horapa o ngā ngaru ultrasonic i roto i te wai, ā, ka pā ki te ine rerekētanga wā me te tika o te rere.​

3. He Whānuitanga o ngā Wai e Pā Ana

• Ka taea e ngā mita wai hiko aukume te ine i ngā wai kawe hiko, tae atu ki te wai paru pakupaku, te wai he nui ngā tote rewa, me ētahi wai para ahumahi he āhuatanga kawe hiko. He pai ēnei mō ngā tukanga ahumahi, ngā tipu maimoatanga wai, me ngā pūnaha tuku wai o te tāone ina kore pea te kounga o te wai e parakore. He tairongo ake ngā mita wai ultrasonic ki ngā totoka iri, ki ngā poke rānei i roto i te wai. Ka taea e ngā totoka iri kukū teitei te marara, te mimiti rānei i ngā ngaru ultrasonic, ka hua ake he inenga hē. Nō reira, ina he nui ngā poke kei roto i te wai, he mārama ngā painga o ngā mita wai hiko aukume.

4. Ngaronga Pēhanga Iti

• Kāore he wāhanga neke o te hanganga o roto o ngā mita wai hikohiko, kāore hoki he arai i te ara rere, ka hua ake he tino iti te ngaronga o te pēhanga i te wā e rere ana te wai. I roto i ngā pūnaha tuku wai nui, he mea nui te whakaiti i te ngaronga o te pēhanga hei whakaiti i te whakapaunga pūngao o ngā papu wai. Nā te rerekētanga o ngā hoahoa, he nui ake ngā ngaronga pēhanga o ngā mita wai ultrasonic, inā koa ko ērā he hanganga arataki rere matatini. Hei pupuri i te tere rere kotahi, me nui ake te pūngao e hiahiatia ana, ka piki ake ai ngā utu whakahaere i te wā roa.
