He whānuitia te whakamahinga o ngā mita rere ultrasonic i roto i ngā ahumahi maha hei ine i te rere o ngā wai me ngā hau. E mōhiotia ana mō tō rātou tika, tō rātou pono, me te kore e pokanoa, ā, he mea rongonui mō ngā tono maha. E rua ngā momo matua o te hangarau mita rere ultrasonic: te tikanga wā-haere me te tikanga Doppler. I roto i tēnei tuhinga, ka rukuhia e mātou ngā rerekētanga i waenga i ēnei hangarau e rua me ā rāua tono.
Ko te kaupapa mahi o te mita rere ultrasonic wā whakawhiti he ine i te wā e horapa ai te tohu ultrasonic ki runga, ki raro hoki i roto i te paipa. Ko te rerekētanga o te wā whakawhiti he rite ki te tere rere o te wai. He pai tēnei hangarau mō ngā wai ma, ōrite me te iti o ngā matūriki, ngā mirumiru hau rānei. He mea whakamahi noa i roto i ngā tono pēnei i te whakahaere wai me te wai para, ngā pūnaha HVAC, me ngā tukanga ahumahi kei reira te wai kāore he poke.
Ko ngā mita rere ultrasonic Doppler, i tētahi atu taha, ka whakamahi i te pānga Doppler hei ine i te tere rere o ngā wai. Ka mahi te hangarau mā te tuku tohu ultrasonic e whakaatahia ana e ngā matūriki, e ngā mirumiru rānei i roto i te wai. Kātahi ka whakamahia te nekehanga auau o te tohu whakaata hei tatau i te tere rere. He pai ngā mita rere Doppler mō ngā wai kei roto ngā matūriki iri, ngā mirumiru hau rānei, ā, koinei te kōwhiringa tuatahi mō ngā tono e pā ana ki ngā paru, ngā wai para totoka me ngā wai hau.
Ko tētahi o ngā rerekētanga matua i waenga i ngā mita rere ultrasonic wā whakawhiti me ngā mita rere ultrasonic Doppler ko tō rātou pai mō ngā momo wai rerekē. Ahakoa he pai te mahi a ngā mita whakawhiti i roto i ngā wai ma, ōrite, he pai ake ngā mita Doppler mō te whakahaere i ngā wai kei roto he paru, he hau rānei. I te wā e whiriwhiri ana i te hangarau mita rere ultrasonic e tika ana mō tētahi tono motuhake, he mea nui kia whakaarohia ngā āhuatanga o te wai e inehia ana.
Ko tētahi atu mea hei whakaaroaro ko te rahi o ngā paipa me ngā rauemi. He pai rawa ngā mita rere ultrasonic mō ngā momo rahi me ngā rauemi paipa, tae atu ki ngā konganuku, ngā kirihou me te raima. E wātea ana ēnei mō ngā paipa iti me ngā paipa nui, ā, he pai mō ngā momo tāutanga. I tētahi atu taha, tera pea he herenga ki te rahi o ngā paipa me te hototahitanga o ngā rauemi ki ngā mita rere Doppler nā te mea he mea nui te noho mai o ngā matūriki, ngā mirumiru hau rānei i roto i te wai mō tā rātou mahi.
Haunga ngā āhuatanga wai me ngā whakaaro mō ngā paipa, me whai whakaaro anō hoki ki te tāutanga me te tiaki i ngā mita rere ultrasonic. Ahakoa e hiahiatia ana he paipa tika mō ngā mita whakawhiti hei ine tika, he ngāwari ake pea ngā whakaritenga tāutanga mō ngā mita Doppler nā te mea ka taea te mahi i te aroaro o ngā matūriki, ngā mirumiru rānei.
Hei whakarāpopototanga, he mea nui te mārama ki ngā momo hangarau mita rere ultrasonic e rua (te wā whakawhiti me te Doppler) hei whiriwhiri i te otinga tika mō tētahi tono motuhake. Mā te whakaaro ki te āhua o te wai, te rahi me te rauemi o te paipa, me ngā whakaritenga tāutanga me te tiaki, ka taea e ngā kaiwhakamahi te whakatau whai whakaaro kia tika ai, kia pono ai hoki ngā inenga rere. Ahakoa te aroturuki i te rere o te wai i roto i tētahi pūnaha ā-tāone, te ine rānei i te rere paru i roto i tētahi tukanga ahumahi, ko te whiriwhiri i waenga i ngā mita rere ultrasonic wā whakawhiti me ngā mita rere ultrasonic Doppler ka pā nui ki te whai huatanga o te otinga ine.
