Ngā Take e Pā Ana ki te Mahi a ngā Mita Wai Ultrasonic

1. Ngā Take e Pā Ana ki te Wai

Ngā Mirumiru Hau i roto i te Wai

He raruraru noa ngā mirumiru hau i roto i ngā pūnaha tuku wai. Inangā rere o te waimā roto i ngā paipa, inā koa i ngā wā ka rerekē te pēhanga wai, ka puta rānei he pūtake o ngā hau rewa, ka taea te hanga i ngā mirumiru hau. Ka horapa ngā ngaru ultrasonic mā roto i te wai mā te wiri i ngā ngota wai. Ko ngā mirumiru hau, me ō rātou ātete oro rerekē rawa atu ki te wai, ka mahi hei whakaata kaha me hei kaiwhakamarara i ngā ngaru ultrasonic. Ina tūtaki te tohu ultrasonic ki ēnei mirumiru hau, ka whakaatahia wawetia te nuinga o te pūngao, ka marara rānei ki ngā taha rerekē. Ka whakararuraru tēnei i te horapa noa o te tohu ultrasonic i waenga i te tuku me te kaiwhiwhi i roto i te mita wai. Nō reira, ka hē pea te whakamārama a te mita i te tohu, ka hua ake he tataunga tere rere me te pānui wai hē.

Te Parapara me ngā Parakore

I roto i te wā, ka kohia e ngā paipa wai te paru, te waikura, me ētahi atu paru. Ka taea e ēnei matū te tau ki ngā pakitara o roto o ngā paipa, ā, i roto i te take o ngā mita wai ultrasonic, ka taea te pani i ngā mata o te transducer. Ka taea e te paru me ngā paru i runga i te transducer te whakaiti i te tohu ultrasonic. Me haere te tohu mā roto i tēnei paparanga o ngā paru i mua i te taenga ki te wai, ā, i roto i tēnei tukanga, ka heke tōna kaha. Hei tāpiri, ko te mata taratara i hangaia e te paru ka meinga ngā ngaru ultrasonic kia marara, ka uaua ai mō te mita te kite tika i te wā - o - te rere, te nekehanga Doppler rānei (i runga i te momo omita wai ultrasonic). Mā tēnei pokanoa ki te tohu ka hua ake he hapa i te ine i te tere rere o te wai, ā, ka hua ake he inenga hē o te rōrahi wai.

2. Ngā Take e Pā Ana ki te Tāutanga

Kōwhiringa Wāhanga Paipa Hē

Te wāhi o temita wai ultrasonicHe mea nui te whakaurunga ki roto i te whatunga paipa. Mena ka whakauruhia te mita ki roto i tētahi wāhanga o te paipa he āhua rere kore-taurite, pērā i te taha o te piko, te tuke, te takirere rānei, ka huri te rere o te wai hei pōrearea. I roto i te rere pōrearea, ka rerekē te tere o te wai puta noa i te wāhanga whakawhiti o te paipa. Kua hangaia ngā mita wai ultrasonic hei ine i te tere rere toharite o te wai. Heoi, ina whakauruhia ki tētahi wāhi rere pōrearea, kāore pea te tere i inehia e tohu ana i te rere whānui i roto i te paipa. Hei tauira, i roto i te piko paipa, ka tere ake te rere o te wai e tata ana ki te pakitara o waho o te piko i te taha o te pakitara o roto. Mena ka ine te mita ultrasonic i te tere i tētahi wāhi e pāngia ana e te wai pakitara o waho e tere ake ana te rere, ka nui rawa te whakatau tata i te tere rere whānui.

Te Whakaritenga Pūoko Hē

He mea nui te whakarite tika o ngā pūoko ultrasonic mō te ine tika. Me whakarite tika ngā pūoko i roto i te mita wai ultrasonic kia tika ai te haere o te tohu ultrasonic i roto i te wai i te ara e taea te matapae. Mena ka hē te whakarite o ngā pūoko, kāore pea te tohu e tae tika ki te pūoko e whiwhi ana. Ahakoa he iti noa te whakarite, ka taea e ngā ngaru ultrasonic te haere i te ara roa ake, i te ara uaua ake rānei i roto i te wai, ka arahi pea ki ngā hapa i roto i te ine i te wā rere, i te nekehanga Doppler rānei. Ka taea e tēnei hapa i puta mai i te whakarite hē te kohikohi i roto i te wā, ā, ka hua ake he rerekētanga nui i roto i ngā pānui wai e pau ana.

3. Ngā Take Taiao

Ngā Rerekētanga o te Pāmahana

He pānga nui tō te pāmahana ki te mahi a ngā mita wai ultrasonic. E pā tika ana te tere o te oro i roto i te wai ki tōna pāmahana. I te huringa o te pāmahana o te wai, ka rerekē anō hoki te tere o te haere o ngā ngaru ultrasonic i roto. Ka whakawhirinaki ngā mita wai ultrasonic ki te mōhiotanga tika mō te tere o te oro i roto i te wai hei tatau i te tere rere. Mena kāore i te tika te whakatikatika o te tikanga utu pāmahana i roto i te mita, kāore rānei e taea te whakaaro mō ngā huringa tere o te pāmahana, ka tatau te mita i te tere rere i runga i te uara hē o te tere o te oro. Hei tauira, ki te piki te pāmahana o te wai, ka piki anō hoki te tere o te oro i roto i te wai. Ki te kore te mita e whakatika mō tēnei pikinga, ka whakaitihia te tere rere nā te mea e whakaaro ana he iti ake te tere o te oro.

Te Whakararuraru Aukume

I roto i ngā taiao hou, he maha ngā pūtake o te pokanoa hikohiko (EMI). Ka pāngia pea ngā mita wai ultrasonic e te EMI, e whakamahi ana i ngā wāhanga hiko hei whakaputa me te whiwhi tohu ultrasonic. Ko ngā pūtake o te EMI ko ngā raina hiko tata, ngā motuka hiko, me ngā tuku reo irirangi. Ka taea e te EMI te pokanoa ki ngā tohu hiko i roto i te mita wai, ka puta he haruru i roto i te tohu ultrasonic kua riro mai. Ka taea e tēnei haruru te whakapohehe i te tohu, ā, ka uaua ki te wae tukatuka tohu o te mita te kite tika i ngā āhuatanga ultrasonic e tika ana mō te ine rere. Nō reira, ka puta pea he pānui hē i te mita wai nā te pokanoa mai i ngā mara hikohiko o waho.

Hei whakamutunga, kia tika ai te whakahaere omita wai ultrasonic, he mea tika kia whakaarohia, kia arohia hoki ēnei āhuatanga e pā ana ki te wai, te tāutanga, me te taiao. Mā te pera, ka taea te whiwhi i ngā inenga pono ake mō te whakamahinga wai, he mea nui tēnei mō te whakahaere wai me ngā pūnaha nama whai hua.
