Ke hoʻouna nei ka mika pae ultrasonic i ka pulse ultrasonic, ʻaʻole hiki i ka mika pae wai ke ʻike i ka echo reflection i ka manawa like. No ka mea he mamao manawa ko ka pulse ultrasonic i hoʻouna ʻia, a he haʻalulu koena ko ka probe ma hope o ka hoʻouna ʻana i ka nalu ultrasonic, ʻaʻole hiki ke ʻike ʻia ka echo reflection i loko o ka manawa, no laila ʻaʻole hiki ke ʻike maʻamau ʻia kahi mamao liʻiliʻi e hoʻomaka ana mai ka ʻili probe/sensor i lalo, ua kapa ʻia kēia mamao ʻo ka ʻāpana makapō. Inā komo ka pae wai kiʻekiʻe loa e ana ʻia i ka ʻāpana makapō, ʻaʻole hiki i ka mika ke ʻike pololei a e hewa. Inā pono, hiki ke hoʻokiʻekiʻe ʻia ke ana pae wai e hoʻokomo. ʻO ka ʻāpana makapō o ka ana pae ultrasonic, e like me ka laulā ʻokoʻa, ʻokoʻa ka ʻāpana makapō. ʻO ka laulā liʻiliʻi, he liʻiliʻi ka ʻāpana makapō, ʻo ka laulā nui, he nui ka ʻāpana makapō. Akā ma ke ʻano laulā ma waena o 30cm a me 50cm. No laila, pono e noʻonoʻo ʻia ka ʻāpana makapō i ka wā e hoʻokomo ai i ka ana pae ultrasonic. Ke komo ka pae wai o ka ana pae ultrasonic i ka ʻāpana makapō, hōʻike pinepine ʻia ke kūlana o ka pae wai e pili ana i ka echo lua.
