Te Mārama ki ngā Wāhanga o te Mita Rere Ultrasonic

I te wā e ine ana i te rere o te wai, he mea rongonui ngā mita rere ultrasonic nā te mea he tika, he kore hoki e pokanoa. Engari he aha tonu ngā mea kei roto i te mita rere ultrasonic? Me titiro tata atu tātou ki ngā wāhanga e hanga ana i tēnei taputapu auaha.

Pūoko: Ko te uho o te mita rere ultrasonic ko te pūoko. Koinei ngā wāhanga e kawenga ana mō te tuku me te whiwhi tohu ultrasonic. I te nuinga o te wā, ka whakamahia he takirua o ngā transducers, ko tētahi hei tuku, ko tētahi hei kaiwhiwhi. I te rere o te wai i roto i te paipa, ka tukuna e te transducer he tohu ultrasonic, ka haere i roto i te wai, ka kohia e te kaiwhiwhi. Mā te ine i te wā e pau ana kia haere te tohu i waenga i ngā pūoko, ka taea te tatau tika i te tere rere o te wai.

Pūtukatuka tohu: Ka tukatukahia te tohu e whiwhihia ana e te pūoko e te pūtukatuka tohu, he wāhanga matua o te mita rere ultrasonic. Ka tātarihia e te pūtukatuka te rerekētanga wā i waenga i ngā tohu i tukuna me ngā tohu i whiwhihia, ā, ka whakamahia ēnei mōhiohio hei tatau i te tere o te wai. Kātahi ka whakamahia ēnei raraunga tere hei whakatau i te tere rere o te wai mā roto i te paipa.

Whakaaturanga me te Putanga: He maha ngā mita rere ultrasonic he wae whakaatu e whakarato ana i ngā raraunga wā-tūturu mō te tere rere, te tere me ētahi atu tawhā e tika ana. Mā tēnei ka taea e te kaiwhakahaere te aroturuki i te rere o te wai me te mahi i ngā whakarerekētanga e tika ana. Hei tāpiri, he maha ngā kōwhiringa putanga o ngā mita rere ultrasonic, pērā i ngā tohu anaro, matihiko rānei, ka taea te whakamahi hei tuku raraunga rere ki tētahi taputapu o waho, ki tētahi pūnaha rānei hei tātari me te tuhi anō.

Hangarau Tuku me te Doppler: Ka taea e ngā mita rere ultrasonic te whakamahi i ngā hangarau e rua hei ine i te rere: te tuku me te Doppler. He pai rawa ngā mita rere ultrasonic wā-haere mō ngā wai ma, ōrite, ā, ka whakawhirinaki ki te wā e pau ana kia haere te tohu ultrasonic ki runga, ki raro hoki i roto i te paipa. I tetahi atu ringa, he pai ngā mita rere ultrasonic Doppler mō ngā wai kei roto ngā matūriki, ngā mirumiru rānei, ā, ka ine i te nekehanga auau o te tohu ultrasonic i a ia e taunekeneke ana me ngā matūriki e neke ana i roto i te wai.

Ngā Taputapu Whakamau Paipa: Hei whakarite i ngā inenga tika, me whakamahi ngā mita rere ultrasonic i ngā taputapu whakamau tika hei hono mārire i te pūoko ki te paipa. Kua hangaia tēnei taputapu hei whakaiti i te pokanoa o te tohu, hei whakarite hoki kia haere te tohu ultrasonic mā roto i te wai me te kore he arai.

Pūtake hiko: Hei whakamutunga, engari ehara i te mea iti rawa, me whai pūtake hiko pono ngā mita rere ultrasonic hei whakahaere. Ka taea tēnei te waiho hei pākahiko mō ngā taputapu kawe, hei hononga hiko tika rānei mō ngā whakaurunga pumau.

Hei whakarāpopototanga, kei roto i te mita rere ultrasonic he pūoko, he tukatuka tohu, he kōwhiringa whakaatu me te putanga, te wā whakawhiti, te hangarau Doppler rānei, ngā taputapu whakairi paipa, me te pūtake hiko. He mea nui te mārama ki ngā wāhanga o te mita rere ultrasonic kia tika ai, kia pono ai hoki ngā inenga rere i roto i ngā momo tono ahumahi me ngā tono arumoni.
