Ka pāngia te tika o ngā mita rere ultrasonic e te poto o te paipa tika?

Ae, ka pā kino te roa o ngā paipa poto ake ki te tika o ngā mita rere ultrasonic - ki te kore e whakaitihia e ētahi atu tikanga. Ko te pūtake o te take ko te whakawhirinaki o ngā mita ultrasonic ki ngā āhuatanga rere pumau hei tatau tika i te tere rere. Kei raro nei he whakamārama taipitopito o te pānga, ngā tikanga matua, me ngā āhuatanga awe:

1. He aha te take e whakararu ai te poto o te paipa tika

• Ngā awhiowhio/ngā porowhita: Nā ngā tuke, ngā tī, ngā takirere, ngā whakaiti rānei i puta ai, e hanga ana i te nekehanga wai hurihuri, pōrearea rānei.
• Ngā pikinga tere kore taurite: He tere ake te neke o te wai i tetahi taha o te paipa i tera taha, kaua e whai i te āhua "parabolic" me te "papatahi" ōrite.

2. Ngā Take e Whakatau ana i te Kaha o te Ngaronga o te Tika

(a) Momo Whakararuraru Rere o Runga

• Ngā raruraru nui (hei tauira, ngā tuke poto-whānui 90°, ngā takirere porowhita, ngā tī, ngā whakaiti): Waihangahia he porowhita kaha e roa ake ai te memeha. Ka taea e te paipa poto, tika (hei tauira, 3D ki runga) i muri i ēnei hononga te whakaputa hapa o te 5%–15%.
• Ngā raruraru ngawari (hei tauira, ngā tuke roa-whānui, ngā takirere kuaha tuwhera katoa): Ka iti ake te whakararuraru i te rere. Ko te paipa poto, tika (hei tauira, 5D ki runga) ka puta pea he hapa o te 1%–3%.

(b) Hangarau Mita (Rerekētanga-Wā vs. Doppler)

• Ngā mita rerekētanga wā: He tino aro ki te ōritetanga o te kōtaha rere, nā te mea ka tatauhia e rātou te tere toharite mai i te iti o ngā ara ultrasonic. He maha ngā hapa nui ake ka puta mai i ngā paipa poto, tika hoki.
• Ngā mita Doppler: Kāore i te tino tairongo, nā te mea ka whakawhirinaki ki ngā tohu marara mai i ngā wai kore-ōrite. Heoi, ka taea tonu e ngā awhiowhio nui te whakaheke i te kitenga tohu me te tika.

(c) Ngā Whakaritenga Tika o te Taupānga

• Mō ngā whakamahinga iti te tika (hei tauira, te aroturukitanga tukanga whānui me te manawanui ±5%), he pai ake pea te whakamahi i tētahi paipa poto ake (hei tauira, 5D ki runga ake i te awa hei utu mō te 10D).
• Mō ngā whakamahinga tino tika (hei tauira, te whakataunga tauhokohoko, te ine pūngao me te ±1% te manawanui), ahakoa he iti noa te whakaiti i te roa o te paipa tika, ka kore pea e tutuki ngā whakaritenga ine.

3. Me pēhea te whakaiti i te ngaronga o te tika mai i ngā paipa poto me ngā paipa tika

• Tāutahia ngā whakangawari rere: Ka whakatauritehia e ngā taputapu pēnei i ngā paihere ngongo, ngā whakangawari honikoma, ngā whakangawari momo-orifice rānei te rere kua whakararuraruhia i te 3D–5D ki runga, ka whakaitihia ngā hapa ki ±1%–2%.
• Whakamahia ngā pūoko maha-ara: ka inehia e ngā mita rawhi-ara 2, 4 rānei te tere i ngā pūwāhi maha puta noa i te paipa, ka toharitehia ngā kōtaha rere kore taurite i puta mai i ngā paipa poto, tika.
• Whakaritea te tūnga o te pūoko: Kaua e tāuta i ngā whakawhiti ira i raro tonu i ngā raruraru. Ki te taea, whakatakotoria te mita ki runga ake i ngā tuke/takirere (he iti noa te pānga o ngā raruraru ki te āhua rere o te wai).
• Whakatikatika i ngā tawhā mita: Mā ngā mita matatau ka taea te whakarerekē i te mokowā whakawhiti, te koki hihi, ngā tautuhinga "whakautu kōtaha rere" rānei hei whakatika i ngā hapa.
