Ko ngā paerewa whakamātautau kounga o ngā mita rere ultrasonic ko ngā āhuatanga e whai ake nei:

Ko ngā paerewa whakamātautau kounga o ngā mita rere ultrasonic te nuinga o ngā āhuatanga e whai ake nei: Ngā tohu mahi: Te tika o te ine: He rite ngā whakaritenga tika mō ngā āhuatanga tono me ngā taumata tika o ngā mita rere ultrasonic. Hei tauira, i roto i ētahi tono ahumahi noa, ka taea te tika i waenga i te ±1% me te ±2%; Mō ngā tono ine uaua ake, me eke pea te tika ki te ±0.5%, ki runga ake rānei. I roto i te kimi, mā te whakamātautau whakatairite me te taputapu rere paerewa, tatauhia te hapa i waenga i te uara ine me te uara paerewa, ka aromatawai mēnā e tutuki ana i ngā whakaritenga tika. Te āheinga ki te tāruarua: e whakaata ana i te ōritetanga o ngā hua ina inehia e te mita rere te tere rere kotahi i raro i ngā āhuatanga kotahi. Ko te hapa āheinga ki te tāruarua me noho i roto i tētahi awhe e whakaaetia ana, pērā i te kore e neke ake i te ±0.2% o te uara ine, me ētahi atu, ko te uara motuhake ka whakawhirinaki ki ngā whakaritenga me ngā whakaritenga tono o te mita rere. Te rārangi: Ko te nui o te whanaungatanga rārangi i waenga i te tohu putanga o te mita rere me te tere rere. Ko te mea pai, me whai hononga rārangi tino tika te putanga o te mita rere ki te tere rere, engari i roto i te mahi ka puta he rerekētanga. Ko te kitenga o te rārangitanga ka whakatauhia mā te ine i ngā pūwāhi rere rerekē, kātahi ka tātari i te rerekētanga o te uara i inehia mai i te whanaungatanga rārangi ā-arotake. Te ōwehenga awhe: Ko te ōwehenga o te tere rere mōrahi ki te tere rere iti rawa ka taea e te mita rere te ine tika. Ko te nui ake o te ōwehenga awhe, ko te whānui ake o te awhe tono o te mita rere. I te nuinga o te wā, me tutuki te ōwehenga awhe o ngā mita rere ultrasonic i ngā hiahia o ngā tono mahi, ā, ko te ōwehenga awhe noa he 10:1 ki te 100:1, teitei ake rānei. Te kounga tohu: Te kaha tohu: Me kaha te tohu ultrasonic e whiwhihia ana e te pūoko kia tika ai te ine me te pumau o te ine. I te kitenga, ka taea te tiro i te uara kaha tohu mā te atanga whakaaturanga o te mita rere, mā te taputapu kimi rānei e tika ana, ā, ko te kaha tohu me noho ki runga ake i tētahi paepae, pērā i te uara Q (taupū kounga tohu) nui ake i te 85, neke atu rānei. Te pumau o te tohu: I te wā e ine ana, me pumau te tohu ultrasonic, ā, kaua e nui ngā piki me ngā heke, ngā wā whakaroa rānei. Ka aromatawaihia te pumau o te tohu mā te mātakitaki i te huringa o te tohu i roto i te wā roa o te ine tonu. Te mahi whakatikatika pāmahana me te pēhanga: Mena he mahi whakatikatika pāmahana me te pēhanga kei te mita rere, me whakamātautau te whai huatanga o te mahi. I raro i ngā āhuatanga pāmahana me te pēhanga rerekē, me taea e te mita rere te whakatikatika tika i ngā hua ine, kia tata ake ai te uara rere putanga ki te tere rere tuturu. Hei tauira, i roto i te taiao he nui ngā huringa pāmahana, me noho te hapa whakatikatika pāmahana o te mita rere i roto i te awhe kua tohua. Te mahi hiko: Te urutau o te pūtake hiko: Me taea e te mita rere te mahi noa i roto i te awhe ngaohiko me te auau o te pūtake hiko kua tohua. Hei tauira, mō te mita rere hiko AC, ina piki te ngaohiko o te pūtake hiko ±10% me te piki te auau ±5%, me taea e te mita rere te mahi noa, ā, kaua e tino pāngia ngā hua ine. Te ātete ārai: Me tutuki i te ātete ārai i waenga i te wāhanga hiko o te mita rere me te whare ngā whakaritenga haumaru, ā, me nui ake te ātete ārai i tētahi uara, pēnei i te 100MΩ, kia mau ai te haumaru i te wā e whakamahia ana. Te āheinga ārai-whakararuraru: Me whai te mita rere i tētahi āheinga ārai-whakararuraru hiko, te whakararuraru auau reo irirangi me ētahi atu āheinga. I te aroaro o ngā pūtake pokanoa o waho, kaua e tino pāngia ngā hua ine o te mita rere. Ka taea te tirotiro i te tika me te pumau o te inenga mā te whakamātautau i roto i te taiao pokanoa whakaata. Ngā whakaritenga hanganga miihini me te tāutanga: Tirotiro āhua: me kore he karawarawa kitea, he rerekētanga, he pakaru me ētahi atu hapa i te anga o te mita rere, me ōrite te paninga mata me te pūmau, ā, me mārama te tautuhi me te papa ingoa me te pānui. Tāutanga pūoko: Me tutuki te tūranga tāutanga o te pūoko ki ngā whakaritenga hoahoa, me pūmau te hononga ki te paipa me te hiri, ā, me tika te koki tāutanga me te ahunga o te pūoko kia pai ai te tuku noa i ngā tohu ultrasonic. Hei tauira, i te wā e tāuta ana i te pūoko ki runga i te paipa whakapae, kia tika te pūoko ki te tuaka paipa; I te wā e tāuta ana ki runga i te paipa poutū, me whiriwhiri te tūranga tāutanga tika kia rite ki te ahunga rere o te wai. Taumata tiaki: Mena ka whakamahia te mita rere i roto i ngā taiao uaua, pēnei i te haumākū, te puehu, te hau waikura me ētahi atu taiao, me tutuki tōna taumata tiaki i ngā whakaritenga, ā, ka taea te ārai i te kino o te taiao o waho ki te mita rere. Ngā tikanga whakatikatika: taputapu paerewa rere: Me whai tiwhikete manatoko whai mana te taputapu paerewa rere e whakamahia ana hei kimi i te mita rere ultrasonic, ā, kaua te koretake o ngā hua ine e neke atu i te 1/3 o te uara hapa mōrahi e whakaaetia ana o te mita rere kia kitea. Ka taea e ngā taputapu paerewa rere te whakamahi i ngā momo taputapu rerekē pērā i te tikanga papatipu, te tikanga rōrahi, te tikanga ripanga paerewa rānei. Wai mō te manatoko: Me waiho te wai e whakamahia ana mō te manatoko hei hau kotahi-wāhanga, kī tonu i te paipa whakamātautau, ā, me noho kore he awhiowhio, he matūriki kitea, he muka me ētahi atu matū i roto i te rere. Mō te mita rere wai, me teitei ake te wai i tōna pēhanga mamaoa kukū, ā, me tutuki te pāmahana, te pēhanga me ētahi atu tawhā ki ngā whakaritenga kua tohua; Mō te mita rere hau, me tutuki hoki te pēhanga, te pāmahana, me te hanganga o te hau ki ngā tikanga e rite ana. Ngā āhuatanga taiao: Me noho te pāmahana, te haumākū me te pēhanga hau o te taiao manatoko ki roto i te awhe kua tohua hei whakarite i te tika o ngā hua whakamātautau. Hei tauira, ko te pāmahana taiao he 5°C ki te 45°C te tikanga, ko te haumākū he 35% ki te 95% RH, ā, ko te pēhanga hauhautanga he 86kPa ki te 106kPa.
