I te ao o te weraweraine pūngao, e rua ngā mita wera hikohiko me ngā mita wera ultrasonic e rongonui ana, ā, he taputapu hangarau matatau anō hoki. Ahakoa te kaupapa kotahi o te ine tika i te whakamahinga wera, he rerekētanga nui kei roto i ngā mātāpono mahi, ngā āhuatanga mahi, me ngā horopaki tono. He mea nui te mārama ki ēnei rerekētanga hei whiriwhiri i te otinga ine wera tino tika mō ngā pūnaha whakamahana me te whakamatao.
1. Ngā Mātāpono Mahi
1.1 Ngā Mita Wera Hikohiko
Ko te mahi a ngā mita wera hiko aukume i runga i te ture a Faraday mō te whakapūngao hiko aukume. I roto i te mita, he papa aukume e hangaia ana e ngā koiri. Ina rere te reo whakamahana kawe hiko, pērā i te wai, mā roto i te ngongo ine o te mita i runga i te poutū ki tēnei papa aukume, ka puta he kaha hiko. E ai ki te ture a Faraday, ko te rahi o tēnei kaha hiko e rite ana ki te tere rere o te reo me te kaha o te papa aukume. Mā te ine i tēnei ngaohiko whakapūngao, katere rereKa taea te whakatau i te nui o te wera e whakamahia ana i roto i te reo whakamahana. Mā te ine i te rerekētanga pāmahana i waenga i ngā paipa tuku me ngā paipa whakahoki, ka taea te tatau tika i te nui o te wera e pau ana. Nā tēnei mātāpono ka tino aro atu ngā mita wera hikohiko ki te rere o ngā wai kawe hiko, ā, ka taea e rātou te whakarato i ngā hua ine pono mena ka mau tonu te kawe hiko o te wai.
1.2 UltrasonicNgā Mita Wera
Ko ngā mita wera ultrasonic, i tētahi atu taha, e whakamahi ana i te kaupapa o te horapa ultrasonic i roto i ngā wai. Kei roto i ēnei he transducers ultrasonic e tuku ana, e whiwhi ana hoki i ngā ngaru ultrasonic. E rua ngā tikanga matua mō te ine rere: te tikanga whakawhiti-wā me te tikanga Doppler. I roto i te tikanga whakawhiti-wā, ka tukuna ngā ngaru ultrasonic ki runga, ki raro hoki i roto i te reo e rere ana. Ka inehia te rerekētanga o te wā horapa o ngā ngaru ultrasonic e haere ana i ngā ahunga whakarunga me raro. E pā ana tēnei rerekētanga wā ki te tere rere o te reo. I te rere o te reo, ka tere ake te ngaru ultrasonic e haere ana ki raro, ko te mea e haere ana ki runga ka puhoi ake. Mā te tatau i tēnei rerekētanga wā me te whakamahi i ngā tātai e tika ana, ka taea te whiwhi i te tere rere. Ko te tikanga Doppler, e pā ana ki ngā wai me ngā matūriki iri, i ngā mirumiru rānei, e ine ana i te nekehanga auau o ngā ngaru ultrasonic e whakaatahia ana mai i ēnei matūriki neke hei whakatau i tetere rereHe rite ki ngā mita wera hikohiko, ka inehia hoki e ngā mita wera ultrasonic te rerekētanga pāmahana i waenga i ngā paipa tuku me ngā paipa whakahoki hei tatau i te whakamahinga wera.
2. Te Tika me te Tairongo o te Ine
2.1 Ngā Mita Wera Hikohiko
Ko ngā mita wera hikohiko he tino tika, he pumau hoki, inā koa mō ngā wai ma, he wai kawe hiko. Kāore i te tino pāngia tō rātou tika e ngā āhuatanga pēnei i te matotoru me te mātotoru o te wai, mena kei te mau tonu te wai hei kawe hiko. Ka taea e rātou te whakatutuki i te taumata tika o te ±0.5% ki te ±1% i raro i ngā āhuatanga mahi noa. Heoi, ki te mea he nui ngā matū kore-kawe hiko kei roto i te wai, pēnei i ngā mirumiru hau, i ngā matūriki kore-kawe hiko rānei, ka taea e ia te whakararuraru i te papa aukume me te whakaiti i te tika o te ine.
2.2 Ngā Mita Wera Ultrasonic
Ko te tika o ngā mita wera ultrasonic e whakawhirinaki ana ki ngā āhuatanga maha, tae atu ki te kounga o ngā transducers ultrasonic, te kounga tāutanga, me ngā āhuatanga o te wai i inehia. I roto i ngā āhuatanga pai, me ngā wai ma me te tāutanga tika, ka taea e ngā mita wera ultrasonic e whakamahi ana i te tikanga wā-haere te whakatutuki i te tika tata ki te ±1% ki te ±2%. Heoi, ko te noho mai o ngā totoka i whakatārewatia, te unahi, ngā mirumiru hau rānei i roto i te wai ka taea te whakararu i te horapa o ngā ngaru ultrasonic, ka arahi ki ngā hapa ine. Ko ngā mita wera ultrasonic momo Doppler, he pai ake mō ngā wai paru, he iti ake te tika i te momo wā-haere, tata ki te ±2% ki te ±5%.
3. Ngā horopaki tono
3.1 HikohikoNgā Mita Wera
He pai rawa ngā mita wera hiko-aukume mō ngā mahi kei reira te reo whakamahana he ma, he kawe hiko hoki, pērā i ngā pūnaha whakamahana pokapū me te wai kua rongoatia, ngā pūnaha whakamahana whare hou, me ngā tukanga ahumahi me ngā wai kawe hiko. Kāore i te tūtohutia kia whakamahia me ngā wai kore-kawe hiko, ngā wai rānei he nui te ihirangi o ngā poke kore-kawe hiko, nā te mea ka raru pea te ine. Hei tāpiri, nā te hanganga o ēnei, me whai paipa tika ngā mita wera hiko-aukume i mua me muri i te tāutanga kia mau ai te rere o te wai, ka taea ai te whakawhāiti i te whakamahinga i roto i ētahi taiao kua herea ki te wāhi.
3.2 Ngā Mita Wera Ultrasonic
He ngāwari ake ngā mita wera ultrasonic i runga i ngā āhuatanga tono. He pai te momo wā whakawhiti mō ngā wai ma, ā, he mea whakamahi noa i roto i ngā pūnaha whakamahana whare noho, i ngā whatunga whakamahana rohe, me ngā pūnaha tuku wai. Ka taea e ngā mita wera ultrasonic momo Doppler te whakahaere i ngā wai me ngā matūriki iri, i ngā mirumiru rānei, kia tika ai mō ngā tukanga ahumahi kei reira pea ngā paru i roto i te wai, pērā i ngā tipu maimoatanga wai para, i ētahi tukanga hanga rānei me ngā wai paru. Heoi anō, kāore e hiahiatia ana e ngā mita wera ultrasonic te roa o te paipa tika pērā i ngā mita wera hikohiko, kia pai ake ai mō ngā tāutanga i roto i ngā wāhi kuiti.
4. Te Tiaki me te Pumau
4.1 HikohikoNgā Mita Wera
He hanganga ā-roto māmā noa iho ngā mita wera hikohiko, kāore he wāhanga neke, ā, ka whakaiti i te tūponotanga o te pakaru me te haehae ā-mīhini. Heoi anō, ka pāngia pea te ngongo ine e te waikura me te tauine i roto i te wā, inā koa ka whakamahia ki ngā wai kei roto ngā matū waikura, ngā taumata tiketike rānei o ngā kohuke. Me tirotiro me te horoi auau i te ngongo ine kia mau tonu ai te tika o te ine. Hei tāpiri, me tiaki ngā koiri hikohiko me ngā irahiko mai i te pokanoa hiko me te kino ā-tinana.
4.2 UltrasonicNgā Mita Wera
Kāore hoki he wāhanga neke o ngā mita wera ultrasonic, ā, ka whai wāhi tēnei ki te pono mō te wā roa. Ko te āwangawanga tiaki matua mō ngā mita wera ultrasonic ko te mahi a ngā transducers ultrasonic. I roto i te wā, ka pakaru pea ngā transducers nā ngā āhuatanga pēnei i te piki me te heke o te pāmahana, te waikura matū, te wiri ā-ringa rānei. Me whakatikatika me te tirotiro auau i ngā transducers kia tika ai te ine. Heoi, ki te whakaritea ki ngā mita wera hikohiko, ko ngā mita wera ultrasonic he iti ake te pānga o te waikura me te tauine wai ki ngā mita wera ultrasonic, ā, ka roa ake te ora i roto i ētahi taiao wai kino.
Hei whakamutunga, he painga me he ngoikoretanga ō ngā mita wera hikohiko me ngā mita wera ultrasonic. He tino pai ngā mita wera hikohiko ki te ine i ngā wai ma, kawe hiko me te tino tika, ko ngā mita wera ultrasonic ia he nui ake te ngāwari i roto i ngā horopaki tono, ā, he pai ake te urutau ki ngā momo āhuatanga wai. I te wā e whiriwhiri ana i waenga i ngā mea e rua, me āta whakaaro ki ngā āhuatanga pēnei i te āhua o te reo whakamahana, te tika o te ine e hiahiatia ana, te wāhi tāutanga, me ngā whakaritenga tiaki kia pai ai te mahi o te wera -pūnaha ine.
