I roto i tētahi paipa poutū e rere ana te wai mai i runga ki raro, he aha te pānga o te tāutanga o ngā pūoko ki te tika o te mita? He aha ngā āhuatanga e pā ana ki tēnei pānga? He aha te momo āhuatanga mahi me matua whakaarohia ina whiriwhiria he wāhi kei te wāhi? I roto i tētahi paipa poutū e rere ana te wai mai i runga ki raro, he tino tūponotanga ka kore e tino kī te paipa i te wai, ā, he nui te mirumiru. Nō reira, ina whakamahia he pūoko ultrasonic mō te ine, ka tatau te mita rere ultrasonic i te tere rere mēnā kua kī te paipa, ā, ka nui ake te uara ine o te mita i te uara tuturu. Ina nui te mirumiru i roto i te wai, ka ngāwari te arahi ki te korenga o te ine o te mita rere ultrasonic. I te wā e whiriwhiri ana i tētahi wāhi tāutanga kei te wāhi, me tāuta ngā pūoko ki te wāhanga o raro o te paipa, ki tētahi tūranga rānei he roa paipa tika te roa e rere ai te wai mai i raro ki runga.
