He rerekē ngā painga me ngā ngoikoretanga o ngā mita rere ultrasonic, e tika ana mō ngā tono motuhake, engari me whai whakaaro anō hoki ki ētahi atu. Kei raro nei he tātaritanga taipitopito mō ō rātou painga me ō rātou ngoikoretanga:
Ngā Painga o ngā Mita Rere Ultrasonic
1. Inenga Kore-Whakauru
Kāore he Whakarerekētanga Paipa:
Ka tāutahia ki waho ki te pakitara o te paipa, kia kore ai e pokanoa ki te rere o te wai. Mā tēnei ka kore e ngaro te pēhanga, te tūponotanga o te aukati, te kino rānei o te mita i ngā wai waikura/whakakoi.
Tāutanga Māmā:
Ka whakaiti i ngā utu tāutanga me te tiaki, inā koa mō ngā paipa whānui te whānui e nui ana te utu mō ngā mita tuku iho.
2. Whānui te Whakamahinga
Ngā Wai Kanorau: He pai mō ngā wai ma, ngā paru, ngā paru, ngā hau, me ngā mea waikura (mēnā ka tukuna e te wai ngā ngaru ultrasonic).
Te Whaihua o te Diameter Nui:
He tino whai hua te utu mō ngā paipa neke atu i te 300 mm, ina kore e taea te whakamahi i ētahi atu mita rere (hei tauira, ngā pereti kōhao).
3. Te Tika me te Tino Tika
Te tika:
Ka taea te whakatutuki i te ±0.5% ki te ±1% i raro i ngā āhuatanga tino pai (hei tauira, te rere pumau, ngā wai ma), he rite ki ngā mita miihini kounga teitei.
Ōwehenga Whānui Huri-Iho:
Ka ine i ngā rere mai i te tere iti ki te tere teitei, kāore he hapa nui.
4. Ngā Āheinga Ine Maha
Rere Ahunga-rua: Ka ine i te rere i ngā taha e rua, he mea whai hua mō ngā tono pēnei i ngā whatunga tohatoha wai, ngā tukanga matū rānei.
Kāore he whakawhirinakitanga ki te pēhanga/te matotoru:
Kāore i te tino pāngia e te pēhanga wai, te matotoru rānei, ki te whakatauritea ki ngā mita miihini (hei tauira, ngā mita tāpine).
5. Ngā Āhuatanga Mamati me te Atamai
Tukatuka Tohu Matatau:
Ka whakamahi i te hangarau matihiko (hei tauira, DSP) hei tātari i te haruru me te whakapai ake i te pumau o te ine.
Whakaurunga Raraunga: He ngāwari te hono atu ki ngā pūnaha PLC, SCADA rānei mō te aroturuki mamao me te takiuru raraunga.
Ngā Huakore o ngā Mita Rere Ultrasonic
1. Te aro ki ngā āhuatanga o te wai me te paipa
Te Tūponotanga/Ngā Mirumiru/Ngā Matūriki:
Ka taea e te nui rawa o te aueue, ngā mirumiru hau, ngā matūriki totoka rānei (hei tauira, i roto i te paru) te marara i ngā tohu ultrasonic, ka whakaiti i te tika, ka kore rānei e tika te ine.
Ngā Whakaritenga Paipa:
Me whai wāhanga roa, tika hoki (ko te nuinga o te wā he 10–20 te whānui o ngā paipa ki runga, e 5 ki raro) kia ōrite ai te rere, he uaua pea tēnei i ngā whakaurunga kuiti.
2. Te Pāmahana me ngā Āhuatanga Oro
Te Whakawhirinakitanga ki te Pāmahana:
Ka rerekē te tere o te ngaru ultrasonic i runga i te pāmahana wai (hei tauira, ±0.5%/°C mō te wai), ā, me whai whakatikatika pāmahana kia tino tika ai.
Whakaiti Oro:
Ka ngoikore pea ngā tohu i ngā wai he nui te mimiti oro (hei tauira, ngā wai matotoru, ngā wai he nui te totoka), ka whakawhāiti i te whānuitanga ine.
3. Te Uaua o te Tāutanga me te Whakatikatika
Whakaritenga Tika:
Me tika te whakanoho i ngā ira whakawhiti (hei tauira, te koki me te tawhiti tika) kia tika ai te rere o ngā ngaru ultrasonic i roto i te wai. Ka puta he hapa ine mēnā he hē te tūnga.
Ngā Wero Whakamātautau:
He uaua te whakatikatika mara nā te mea e whakawhirinaki ana ki ngā āhuatanga o te paipa; kāore pea te whakatikatika wheketere e tino whai whakaaro ki ngā taurangi kei te papaanga.
4. Te Utu me te Tohungatanga Hangarau
Te utu tīmatanga teitei ake:
He nui ake te utu i ngā mita miihini taketake (hei tauira, ngā mita hoe wira) mō ngā paipa iti te whānui.
Ngā Whakaritenga Pūkenga Hangarau: Ko te tāutanga me te rapurongoā e hiahia ana ki te tohungatanga ki te hangarau ultrasonic me ngā whanaketanga wai.
5. Ngā Here i roto i ngā Horopaki Motuhake
Tere Rere Iti:
He uaua ki te rere o ngā rerenga wai tino iti (hei tauira, <0.1 m/s) nā te iti o te rerekētanga wā i waenga i ngā tohu whakarunga/whakararo.
Te Pāmahana/Pēhanga Teitei:
E whakawhāitihia ana e ngā rauemi whakawhiti; kāore e tika mō ngā pāmahana tino kino (hei tauira, >200°C) me ngā pēhanga kāore he hoahoa motuhake.
He tino pai ngā mita rere ultrasonic mō ngā tono e hiahia ana kia kore e pokanoa, kia tino tika te ine i ngā wai nui, ngā wai uaua rānei (hei tauira, te maimoatanga wai, te hau māori). Heoi, me āta whakaaro ki ngā āhuatanga o te paipa, ngā āhuatanga o te wai, me te tohungatanga tāutanga. Mō ngā taiao he rere kore pumau, he nui te ihirangi totoka, he kiki rānei ngā wāhi tāutanga, he pai ake pea ngā mita rerekē (hei tauira, ngā mita hikohiko, ngā mita vortex rānei).
