He wero ngā tere rere nui ki ngā rohe ine o raro me o runga o ngā mita rere ultrasonic, ā, ka hua ake he rerekētanga nui i roto i te mahi tika:
Tere Rere Iti (< 0.1 m/s)
I tēnei wā, kua tata te rere waenga ki te rere laminar, ā, he iti te ōritetanga o te tohatoha tere. Ko ngā mita rere kotahi-ara, e ine ana i te tere rere i te pokapū paipa anake, ka kite i te whānui haere o te hapa tahuritanga mai i te ±1% ki te neke atu i te ±3%. He rerekē, ka taea e ngā mita rere maha-ara te pupuri i te tika o te ±0.5% ki te ±1% mā te ine i ngā tere i ngā pūwāhi maha me te tatau i te toharite taumaha. Heoi, me whiriwhiri te "momo tere rere-iti motuhake" (me te whakanui tohu teitei ake).
Te Tere Rere Nui (> 10 m/s)
Ka puta he haruru pōrearea i te rere tere-rahi, ā, ka iti haere te rerekētanga wā o te horapa o te ngaru ultrasonic (ka uaua ki te hopu tika), ka arahi pea tēnei ki ngā rerekētanga o te rere inamata. Me whiriwhiri he mita rere "momo tauira auau-teitei" (me te auau tauira ≥ 100 Hz) me te whakarite kia piri te hononga i waenga i te pūoko me te paipa (hei whakaiti i te pokanoa wiri).
