He pēhea te mahi a te mita rere ā-roto? He aratohu māmā

He taputapu nui ngā mita rere i roto i ngā ahumahi pēnei i te hanga, te maimoatanga wai, te hinu me te hau, me te tukatuka kai. Ka ine i te tere rere o ngā wai me ngā hau, hei āwhina i te aroturuki me te whakahaere tika i ngā tukanga. Ko te mita rere ā-roto he momo mita rere motuhake e tāuta tika ana ki roto i te paipa, ko te tikanga ka rere te wai mā roto i te mita tonu. Engari me pēhea te mahi a te mita rere ā-roto, ā, he aha te hiranga? I roto i tēnei tuhinga, ka tūhuratia e mātou te mahi a ngā mita rere ā-roto me pēhea e āwhina ai rātou ki te arotau i ngā mahi.

1. He aha te Mita Rere ā-Rāina?

He taputapu te mita rere ā-roto i hangaia hei ine i te tere rere o te wai (wai, hau rānei) i roto tonu i te paipa. Kāore i rite ki ngā mita rere whakapiripiri, e piri ana ki waho o te paipa, ka tāutahia ngā mita rere ā-roto ki roto i te paipa, ka waiho hei wāhanga nui o te pūnaha kawe wai. Ko te tikanga ka haere te wai mā te mita rere i te wā e mahi noa ana.

He maha ngā momo mita rere ā-roto e wātea ana, ia momo i hangaia hei ine i te rere mā te whakamahi i ngā tikanga rerekē. Ka uru atu pea ēnei tikanga ki ngā hangarau miihini, hikohiko, ultrasonic, turbine, me Coriolis.

2. He pēhea te mahi a te mita rere ā-roto?

Ko te mātāpono mahi o te mita rere ā-roto e whakawhirinaki ana ki te hangarau e whakamahia ana hei ine i te rere. Kei raro nei, ka tirohia ngā momo mita rere ā-roto e tino kitea ana, me te whakamārama i tā rātou mahi.

Ngā Mita Rere o te Tīpene

He rotor te mita rere o te tāpine e whakatakotoria ana ki te ara rere. I te rere o te wai i roto i te mita, ka huri te rotor. He rite tonu te tere o te hurihanga o te rotor ki te tere rere o te wai. Ka kitea e te pūoko te nekehanga o te rotor, ka hurihia hei tohu hiko, kātahi ka tukatukahia hei whakatau i te tere rere.

• Te āhua o tana mahi:Ka nui ake te wai e rere ana, ka tere ake te hurihuri o te rotor, ā, ka teitei ake te tere rere.

Ngā Mita Rere Hikohiko

Ko te mahi a ngā mita rere hiko aukume i runga i te Ture Whakaoho a Faraday, e kī ana, ina neke te wai kawe hiko i roto i te papa aukume, ka puta he ngaohiko. I roto i ēnei mita, ka whakanohoia ngā irahiko ki roto i te paipa, ā, ka puta he papa aukume poutū ki te rere o te wai. I te nekenga o te wai i roto i te papa aukume, ka inehia te ngaohiko whakaoho e ngā irahiko, ā, ka tatauhia te tere rere.

• Te āhua o tana mahi:He rite te ngaohiko whakaoho ki te tere o te wai kawe hiko, ā, ka whakamahia tēnei ngaohiko hei tatau i te tere rere.

Ngā Mita Rere Ultrasonic

Ka whakamahia e ngā mita rere ultrasonic ā-roto ngā ngaru oro hei ine i te rere o te wai. Ka mahi mā te tuku tohu ultrasonic mā roto i te wai, me te ine i te wā e haere ai ngā tohu i waenga i ngā transducers. Ka whakatauhia te tere rere i runga i te rerekētanga o te wā rere o ngā tohu, e pāngia ana e te tere rere.

• Te āhua o tana mahi:Mena kei te neke te wai, ka poto ake te wā e haere ana te tohu ultrasonic i te ahunga kotahi me te rere i te tohu e haere ana ki te taha o te rere. Ka whakamahia te rerekētanga wā hei tatau i te tere rere.

Ngā Mita Rere Coriolis

Ka inehia e ngā mita rere Coriolis te rere o te papatipu mā te kite i te piko o ngā ngongo wiri i te wā e haere ana te wai i roto i aua ngongo. Kei roto i ēnei mita tētahi, neke atu rānei, o ngā ngongo e wiri ana i te auau pumau. Ina rere te wai i roto i ngā ngongo, ka puta he nekehanga i roto i te tauira wiri. Ko te nui o tēnei nekehanga e pā tika ana ki te tere rere o te papatipu.

• Te āhua o tana mahi:Ka inehia te panoni o te tauira wiri o ngā ngongo, ka hurihia hei pānui rere. He tino whai hua ngā mita Coriolis mō te ine i te rere papatipu o ngā wai me ngā hau.

3. Ngā Painga o ngā Mita Rere ā-Rāina

He maha ngā painga o ngā mita rere ā-roto, ā, he mea tino pai mō ngā tono maha:

• Ine tika:Mā ngā mita ā-roto ka ine tika te rere o te wai i te wā tūturu, kia tika ake ai te aroturuki me te whakahaere i te tere rere.
• He whānuitanga o ngā momo wai:Ka taea te whakamahi i ngā mita rere ā-roto hei ine i te tini o ngā wai, tae atu ki te wai, te hinu, ngā matū me ngā hau.
• Te ōritetanga:He pumau ake, he pono ake hoki ngā mita ā-roto i te roanga o te wā, ki te whakaritea ki ētahi tikanga ine o waho, inā koa ka pāngia te pūnaha e ngā huringa pehanga, e ngā tere rere teitei rānei.
• Ngā mahi maha:I runga i te momo mita rere ā-roto, ka taea e rātou te ine i te tere rere me ētahi atu tawhā pēnei i te pāmahana, te pēhanga, me te rere papatipu, kia puta ai he raraunga whānui ake.

4. Ngā Whakamahinga o ngā Mita Rere ā-Rāina

E whakamahia ana ngā mita rere ā-roto i roto i te maha o ngā ahumahi hei whakarite i te maeneene me te whai hua o ngā mahi:

• Te maimoatanga wai me te wai para:Mā ngā mita rere ā-roto ka āwhina i te aroturuki i te rere o te wai mā roto i ngā tipu maimoatanga, me te whakarite kia tika te nui o ngā matū e tāpirihia ana i ia wāhanga.
• Hinu me te hau:He mea nui ngā mita rere ā-roto mō te ine i te rere o te hinu mata, te hau māori, me ngā hua kua parakore i roto i ngā paipa me ngā pūnaha tohatoha.
• Kai me te inu:E whakamahia ana ēnei mita hei whakarite i te ine tika me te whakaranu i ngā kai i roto i te hanga inu, hua miraka, me ngā kai tukatuka.
• Ngā rongoā me ngā matū:Mā ngā mita rere ā-roto ka āwhina i te whakahaere i te rere o ngā wai i roto i ngā tauhohenga, ā, ka whakarite kia tika te whakaranu me te ine i roto i te hanga matū me te rongoā.

5. Whakamutunga

He taputapu kaha ngā mita rere ā-roto mō te ine i te rere o ngā wai me ngā hau i roto i te paipa. Ahakoa he whakamahi i te tāpine, te hikohiko, te ultrasonic, te hangarau Coriolis rānei, ka whakaratohia e ēnei mita he raraunga tika me te wā-tūturu hei āwhina i te aroturuki me te whakahaere i ngā pūnaha wai. Nā te kaha ki te ine tika i te rere i roto i ngā paipa whakahaere, he mea tino nui ngā mita rere ā-roto i roto i ngā ahumahi e hiahia ana ki ngā inenga rere tika mō ngā mahi whai hua me te haumaru.

Ko te whiriwhiri i te mita rere ā-roto tika e whakawhirinaki ana ki ngā hiahia motuhake o tō tono, te momo wai e inehia ana, me te taumata o te tika e hiahiatia ana. Ahakoa te hangarau e whakamahia ana, he mea nui te mahi a ngā mita rere ā-roto ki te arotau i ngā tukanga, te whakapai ake i te mahi a te pūnaha, me te whakarite i te whakahaere wai pono.
