I roto i ngā mahi ahumahi maha, he mea nui te whiriwhiri i te mita rere tika hei whakarite i te whai huatanga me te tika o te aroturuki me te whakahaere i ngā pūnaha wai. E rua ngā momo mita rere rongonui—ngā mita rere o te tāpinemengā mita rere ultrasonic—he rerekē ngā painga o ia hangarau, o ia hangarau, i runga anō i ngā whakaritenga motuhake o te tukanga. Mā te mārama ki te whakataurite o ēnei hangarau e rua ka āwhina i ngā ahumahi ki te whiriwhiri i te otinga tika mō ā rātou hiahia.

 

• Ngā Mita Rere o te Tīpene

Ngā mita rere o te tāpoiine i te rere o te wai mā te kite i te hurihanga o te tāpine kei roto i te ara rere. I te rerenga o te wai mā te mita, ka huri te tāpine, ā, he rite tonu te tere o te hurihanga ki te tere rere. E mōhiotia ana ngā mita rere tāpine mō ā rātoutino tikai te wā e ine ana i ngā rere ma, pumau o ngā wai me ngā āhuatanga wai pumau.

He tino whai hua ēnei mita mō te ine i ngā wai pērā i te wai, i ētahi atu wai ma, kāore i te matotoru. Heoi, he iti noa ngā herenga o ngā mita tāpine. Ka whakawhirinaki ēnei ki ngā wāhanga neke, ka pakaru pea i roto i te wā, ā, kāore pea e pai te mahi ki ngā wai he matotoru teitei, he mirumiru, he matūriki rānei. Nō reira, he pai rawa atu ngā mita tāpine mō ngā tono kei reira ngā āhuatanga wai e ōrite ana, e taea ana te matapae.

• Ngā Mita Rere Ultrasonic

Ngā mita rere orooroHe rerekē te mahi a ngā mita rere ultrasonic i ngā mita tāpine. Engari i te whakamahi i ngā wāhanga neke, ka inehia e ngā mita rere ultrasonic te wā e haere ai ngā ngaru oro i roto i te wai. E rua ngā momo matua o ngā mita rere ultrasonic:wā whakawhitimeDoppler.

Ngā Mita Rere Ultrasonic Wā-WakaKa inehia e ēnei mita te rerekētanga o te wā e pau ana i ngā ngaru oro e haere ana ki runga, ki raro hoki i roto i te wai. He mea tino pai mō ngā wai ma, ōrite pērā i te wai, ā, he tino tika, he tino tika hoki. He whānuitia te whakamahinga o ēnei mita i roto i ngā tono pēnei i tete maimoatanga waimengā tukanga ahumahite wāhi e rere ai ngā wai ma i roto i ngā paipa.

Ngā Mita Rere Ultrasonic Doppler: Kua hangaia ēnei mita hei ine i ngā wai kei roto ngā totoka whakatārewatia, ngā mirumiru, ngā matūriki rānei. Ka whakaatahia e ngā mita ultrasonic Doppler ngā ngaru oro mai i ngā matūriki, ngā mirumiru rānei i roto i te wai, kia taea ai e rātou te ine i te rere i roto i ngā āhuatanga uaua ake. He pai mō ngā tono pēnei i tete maimoatanga wai paramete ine i te paru.

 

Ngā Rerekētanga Matua i waenga i ngā Mita Rere Turbine me ngā Mita Rere Ultrasonic

• Hototahitanga Wai:Ngā mita rere o te tāpoihe pai te mahi me ngā wai ma, pumau engari ka uaua ki ngā wai he matotoru teitei, he totoka, he mirumiru rānei.
• Ngā mita rere orooroHe nui ake ngā āhuatanga ka taea te whakamahi, me ngā tauira Doppler e tika ana mō ngā wai he totoka, he mirumiru rānei kei roto, ko ngā mita wā-haerenga ia he tino pai mō ngā wai ma, ōrite.

Te tika:

• Ngā mita rere o te tāpoihe tika mō ngā rere ma, pumau, ā, he pai te tika o ngā rerenga i ngā āhuatanga tino pai.
• Ngā mita rere oroorohe tino tika hoki, inā koa i roto i ngā wai ma (te wā whakawhiti) me ngā wai matatini (Doppler).

Te tiaki:

• Ngā mita rere o te tāpoika uru atu ki ngā wāhanga mīhini, ā, me nui ake te tiaki i ngā wā katoa nā te pakaru me te haehae o ngā wāhanga neke.
• Ngā mita rere oroorokāore he wāhanga e neke ana, nō reira he iti ake ngā whakaritenga tiaki me te roa ake o te ora ratonga.

Ngāwari o te Tāutanga:

• Ngā mita rere o te tāpoihe maha ngā wā e hiahiatia ana te tāutanga tika, ā, he pai ake hoki mō ngā rahi paipa me ngā tere rere motuhake.
• Ngā mita rere orooro, inā koa ngā mita wā-haere, he ngāwari ake ngā kōwhiringa tāutanga, ā, ka taea te whakamahi i roto i ngā whirihoranga ā-roto me ngā whirihoranga whakapiri. He rite tonu te ngāwari o ngā mita Doppler engari he tino whai hua mō ngā tāutanga uaua ake.
