2. Na'urorin sarrafa nesa don kayan aikin gida, kayan wasan yara, da sauran na'urorin lantarki;
3. Ultrasonic watsi da na'urorin liyafar don rigakafin sata da kayan rigakafin bala'i.
4.Ana amfani da shi wajen korar sauro, kwari, dabbobi da sauransu.
Sanarwa
1. Mai watsawa na ultrasonic yana fitar da katako na ultrasonic a kusurwar digiri 60 a waje, don haka kada a sami wasu cikas tsakanin binciken da abin da aka auna.
2. Tsarin ultrasonic yana auna nisa a tsaye tsakanin abin da aka auna da bincike, kuma ya kamata a kiyaye binciken yana fuskantar abin da aka auna yayin aunawa.
3. Ultrasonic ma'auni yana rinjayar saurin iskar muhalli, zazzabi, da dai sauransu.
Matsaloli masu yiwuwa
1. Saboda tasirin rashin daidaituwa na abin da aka auna, kusurwar tunani, saurin iska da zafin jiki, da kuma tunani da yawa, raƙuman ruwa na ultrasonic na iya ƙara yawan kurakuran bayanai.
2. Saboda halayen halayen duban dan tayi a cikin auna ma'aunin makafi, idan matsayin ma'aunin ya canza kuma bayanan da aka karɓa ya kasance ba canzawa yayin aunawa kusa, yana nuna cewa an shigar da ma'aunin ma'auni.
3. Idan ba a dawo da bayanan ma'auni ba lokacin da tsarin ke auna abubuwa masu nisa, yana iya kasancewa a waje da kewayon auna ko kusurwar ma'auni na iya zama kuskure.Ana iya daidaita kusurwar ma'auni daidai.
