Te kaupapa mahi wā-haere
Te Mātāpono o te Ine:
Ka whakamahia e te Mātāpono Hononga Wā-Waenga te meka e pāngia ana te tere rere o te reo kawe i te wā rere o te tohu ultrasonic. Pērā i te kauhoe e whiti ana i te awa e rere ana, ka pōturi ake te haere o te tohu ultrasonic i te awa whakarunga i te awa whakararo.
Tō mātouNgā mita rere ultrasonic TF1100mahi kia rite ki tēnei mātāpono wā-haerenga:
Vf = Kdt/TL
Kei hea:
Te tere rere o te Vc
K: Pūmau
dt: Te rerekētanga o te wā rere
TL: Te Wā Whakawhiti Ave Rage
Ina mahi te mita rere, ka tukuna, ka whiwhi hoki ngā whakawhiti e rua i ngā tohu ultrasonic kua whakanuia e te maha o ngā hihi e haere ana i te tuatahi ki raro, kātahi ki runga. Nā te mea he tere ake te haere o te oro ultra ki raro i te taha whakarunga, ka rerekē te wā rere (dt). Ina marino te rere, ka kore te rerekētanga wā (dt). Nō reira, i te mea e mōhio ana tātou ki te wā rere i raro me te taha whakarunga, ka taea e tātou te mahi i te rerekētanga wā, kātahi ka tere te rere (Vf) mā te tātai e whai ake nei.

Te kaupapa whakahaere o te Doppler
TeDF6100Ka mahi te mita rere raupapa mā te tuku i te oro ultrasonic mai i tana transducer tuku, ka whakaatahia te oro e ngā whakaata oro whai hua e iri ana i roto i te wai, ā, ka tuhia e te transducer whiwhi. Mena kei te neke ngā whakaata oro i roto i te ara tuku oro, ka whakaatahia ngā ngaru oro i te auau kua nekehia (auau Doppler) mai i te auau kua tukuna. Ka pā tika te nekehanga o te auau ki te tere o te matūriki, o te mirumiru rānei e neke ana. Ka whakamāramahia tēnei nekehanga o te auau e te taputapu, ā, ka hurihia ki ngā waeine ine kua tautuhia e te kaiwhakamahi.
Me nui ētahi matūriki hei whakaata roa - he nui ake i te 100 maikorona te rahi.
I te wā e tāuta ana i ngā whakawhiti hiko, me nui te roa o ngā paipa tika i te wāhi tāutanga ki runga, ki raro hoki. I te nuinga o te wā, me 10D te roa o ngā paipa tika mō te taha whakarunga, ā, me 5D te roa o te paipa tika mō te taha whakarunga, ko D te diameter o te paipa.
Te kaupapa mahi o te tere o te rohe
DOF6000Ka whakamahia e te mita rere awa tuwhera raupapa te Doppler Aratau Tonu hei kite i te tere o te wai, ka tukuna he tohu ultrasonic ki roto i te rere o te wai, ā, ka whiwhihia ngā whakaata (whakaata) e whakahokia mai ana i ngā matūriki e iri ana i roto i te rere o te wai, ka tātarihia hei tango i te nekehanga Doppler (tere). Ka haere tonu te tuku, ā, ka rite tonu ki te whiwhinga tohu kua whakahokia mai.
I roto i te huringa ine, ka tukuna e Ultraflow QSD 6537 he tohu tonu, ā, ka ine i ngā tohu e hoki mai ana mai i ngā mea whakamarara i ngā wāhi katoa o te hihi. Ka whakatauhia ēnei ki te tere toharite ka taea te hono atu ki te tere rere o te awa i ngā wāhi e tika ana.
Ka kitea e te kaiwhiwhi i roto i te taputapu ngā tohu whakaata, ā, ka tātarihia aua tohu mā te whakamahi i ngā tikanga tukatuka tohu mamati.
Te Ine i te Hōhonutanga o te Wai – Ultrasonic
Mō te ine i te hohonutanga, ka whakamahia e Ultraflow QSD 6537 te Time-of-Flight (ToF) Ranging. Kei roto i tēnei ko te tuku i te pahūtanga o te tohu ultrasonic ki runga ki te mata o te wai, me te ine i te wā e pau ana kia tae mai te haruru mai i te mata ki te taputapu. He rite te tawhiti (te hohonutanga o te wai) ki te wā whakawhiti me te tere o te oro i roto i te wai (kua whakatikatikaina mō te pāmahana me te mātotorutanga).
Ko te ine hohonu mōrahi o te ultrasonic e herea ana ki te 5m.
Te Ine i te Hōhonutanga o te Wai – Te Pēhanga
Kāore pea ngā wāhi kei roto i te wai he nui ngā paru, he mirumiru hau rānei, e pai mō te ine i te hohonu o te wai mā te whakamahi i te ultrasonic. He pai ake ēnei wāhi mō te whakamahi i te pēhanga hei whakatau i te hohonu o te wai.
Tērā pea ka taea te ine i te hohonutanga i runga i te pehanga ki ngā wāhi kāore e taea te whakanoho i te taputapu ki te papa o te awa rere, kāore rānei e taea te whakairi whakapae.
Kei te Ultraflow QSD 6537 he pūoko pēhanga tino pai e 2 ngā pae. Kei te mata o raro o te taputapu te pūoko, ā, e whakamahi ana i tētahi wāhanga pūoko pēhanga matihiko kua whakatauritea te pāmahana.
I ngā wā e whakamahia ana ngā pūoko pēhanga hohonu, ka puta he hapa i roto i te hohonutanga kua tohua i roto i te rerekētanga o te pēhanga hauātea. Ka whakatikahia tēnei mā te tango i te pēhanga hauātea mai i te pēhanga hohonu kua inehia. Me whakamahi he pūoko pēhanga hauātea hei mahi i tēnei. Kua hangaia he kōwae whakaea pēhanga ki roto i te Calculator DOF6000, ā, ka whakaea aunoatia ngā rerekētanga o te pēhanga hauātea kia tino tika ai te ine hohonu. Mā tēnei ka taea e Ultraflow QSD 6537 te ripoata i te hohonutanga wai (pēhanga) tuturu hei utu mō te pēhanga hauātea me te upoko wai.
Te pāmahana
Ka whakamahia he pūoko pāmahana āhua totoka hei ine i te pāmahana o te wai. Ka pāngia te tere o te oro i roto i te wai me tōna kawe hiko e te pāmahana. Ka whakamahia e te taputapu te pāmahana i inehia hei whakatikatika aunoa i tēnei rerekētanga.
Te Arahi Hiko (EC)
Kei te Ultraflow QSD 6537 te kaha ki te ine i te kawe hiko o te wai. Ka whakamahia he whirihoranga hiko e whā hei ine. Ka tukuna he iahiko iti mā roto i te wai, ā, ka inehia te ngaohiko i puta mai i tēnei iahiko. Ka whakamahia e te taputapu ēnei uara hei tatau i te kawe hiko mata kāore anō kia whakatikatikaina.
