Ngā Otinga mō ngā Wero Ine i te Mita Rere Ultrasonic i roto i ngā Āhuatanga Rere Maha-wāhanga

I roto i ngā mahi ahumahi, he maha ngā wā ka tūtaki ngā mita rere ultrasonic ki ngā āhuatanga uaua ina he ranunga maha-wāhanga te reo i roto i te paipa, pērā i te huinga o te hau me te wai, kei roto rānei he paru me ngā poke. Ka taea e tēnei rere maha-wāhanga te whakararuraru nui i ngā tohu ultrasonic, ka hua ake he uara ine koretake me te hē. Kei raro nei ngā otinga whai hua hei whakatika i ēnei wero.

Arotau Tawhā mō te Rere Maha-wāhanga​

1. Ngā Tautuhinga Tātari

• Tātari Urutau: Whakatinanahia ngā rauropi tātari urutau ki roto i te wae tukatuka tohu o te mita rere. Ka taea e ēnei rauropi te whakarerekē aunoa i ngā tawhā tātari i runga i ngā āhuatanga o ngā tohu ultrasonic e tae mai ana. Hei tauira, ina puta he haruru ohorere, he pikinga pokanoa rānei nā ngā mirumiru hau, ngā matūriki paru rānei, ka taea e te tātari urutau te urutau tere ki te whakaiti i ēnei tohu rerekē, ā, mā reira ka whakapai ake i te ōwehenga tohu-ki-te-haruru.​

• Tātari Toharite Neke: Ka taea te whakamahi i tētahi tātari toharite neke hei whakangawari i ngā uara rere kua inehia. Mā te tatau i te toharite o tētahi raupapa o ngā pūwāhi raraunga ine karapīpiti i roto i tētahi matapihi wā motuhake, ka taea te whakaiti i ngā rerekētanga poto i puta mai i te rere maha-wāhanga. Hei tauira, ki te tauirahia e te mita rere ngā raraunga i ia 0.1 hēkona, ka taea te whakamahi i tētahi toharite neke 1-hekona (arā, te toharite i te 10 ngā pūwāhi raraunga karapīpiti) hei whakarato i tētahi putanga pumau ake. Heoi, he mea nui kia mōhio ko tētahi matapihi wā roa rawa ka whakaroa i te urupare ki ngā huringa rere tuturu, nō reira me hanga he taurite kia rite ki ngā whakaritenga tono motuhake.

2. Te Whakatikatika i te Paepae Tohu

• Whakatakotoria ngā paepae tohu e tika ana mō te kaha me te auau. I roto i te taiao rere maha-wāhanga, ka rerekē pea ngā tohu ultrasonic e whiwhihia ana e te mita rere mai i ngā tohu rere kotahi-wāhanga noa i runga i te kaha me te auau. Mā te tātari tupato i ngā āhuatanga tohu noa i te aroaro o te rere maha-wāhanga i roto i te pūnaha paipa motuhake, ka taea te whirihora i te mita rere kia kore e aro ki ngā tohu e taka ana i waho o te awhe paepae kua tautuhia. Ka āwhina tēnei ki te whakakore i ngā tohu teka i puta mai i ngā mirumiru hau, ngā poke, ngā tauira rere pōrearea rānei kāore e pā ana ki te rere papatipu tuturu o te wai matua.

Ngā Tauira Mita Rere e Manakohia ana mō te Rere Maha-wāhanga​

1. Ngā Mita Rere Ataata Doppler

• He tino pai ngā mita rere ultrasonic Doppler mō ngā tono rere maha-wāhanga kei reira ngā matūriki totoka, ngā mirumiru hau rānei i roto i te wai. Ka mahi ēnei mita rere i runga i te pānga Doppler, e puta ana ina whakaatahia he ngaru ultrasonic mai i ngā matūriki neke, i ngā mirumiru rānei i roto i te wai. Ko te nekehanga auau o te ngaru whakaata he rite ki te tere o ngā mea neke. Hei tauira, i roto i tētahi tipu maimoatanga wai para kei reira ngā totoka iri me ētahi hau rewa i roto i te para, ka taea e te mita rere ultrasonic Doppler te ine tika i te tere rere mā te kite i te nekehanga o ēnei wāhanga kore-rite i roto i te wai.​

• Kua hangaia ēnei hei whakahaere i ngā wai me te rerekētanga o ngā momo wai, ā, ka taea te whakarato i ngā inenga rere pono ahakoa te nui o ngā matūriki, ngā mirumiru rānei. Kei roto hoki i ētahi mita rere ultrasonic Doppler matatau ngā rauropi tukatuka tohu kua hangaia mō ngā āhuatanga rere maha-wāhanga, hei whakarei ake i te tika o tā rātou inenga.

2. Ngā Mita Rere Ultrasonic Maha-hongere​

• Ka whakamahia e ngā mita rere ultrasonic maha-hongere he maha ngā takirua o ngā transducers ultrasonic kua whakanohoia ki ngā tūranga rerekē huri noa i te wāhanga whakawhiti o te paipa. Mā tēnei whirihoranga ka taea te ine whānui ake i te kōtaha rere i roto i te paipa. I roto i ngā āhuatanga rere maha-wāhanga, ka tino koretake te tohatoha rere, me ngā mirumiru hau, ngā wāhanga paru taumaha rānei e kukū ana ki ētahi wāhi o te paipa.

• Mā te ine i te tere rere i ngā pūwāhi maha puta noa i te paipa, ka taea e te mita rere ultrasonic maha-hongere te arotake pai ake i ēnei kore-taurite me te tatau i te tere rere toharite tika ake. Hei tauira, i roto i te paipa hinu-hau e taea ai te wehewehe i te ranunga hau-wai ki ngā paparanga rerekē, ka taea e te mita rere maha-hongere te ine i ngā āhuatanga rere o ia paparanga motuhake, kātahi ka whakakotahi i ngā raraunga hei whiwhi i te ine rere tika whānui.

Whakamutunga

Ina mahi tahi me te rere maha-wāhanga i roto i ngā tono mita rere ultrasonic, mā te arotakenga tawhā pēnei i te tātari tika me te whakatikatika i te paepae tohu ka tino whakapai ake i te tika o te ine. Hei tāpiri, mā te whiriwhiri i te tauira mita rere tika, pēnei i te Doppler, i ngā mita rere ultrasonic maha-hongere rānei, i whakaritea ki ngā āhuatanga rere maha-wāhanga motuhake ka taea te whakarite i ngā inenga rere pono me te pumau.
