Ae, he maha ngā paerewa ahumahi mō te whakatikatika i ngā mita rere ultrasonic, he mea nui hei whakarite i te tika me te pono o te ine. Anei ngā mea matua:
Ngā Paerewa o te Ao
ISO 24192:2020: E whakamārama ana i ngā tikanga me ngā whakaritenga mō te whakatikatika me te manatoko i ngā mita rere ultrasonic. E kapi ana i tēnei te whakatikatika, te manatoko, me ngā tikanga aromatawai mō ngā momo mita rere ultrasonic, tae atu ki ngā mita rere kotahi-kurupae, maha-kurupae, me te maha-ara. E whakamārama ana te paerewa i ngā kupu me ngā whakamāramatanga, ngā tukanga whakatikatika, ngā tukanga manatoko, me te whakatau tata i te koretake.
ISO 15155:2017: E whakatakoto ana i ngā tikanga ine mō ngā āhuatanga ultrasonic o ngā mita rere ultrasonic, tae atu ki ngā āhuatanga hihi oro, ngā āhuatanga urunga, me ngā āhuatanga whakaata. E kapi ana te paerewa i te ine i ngā āhuatanga ultrasonic pēnei i te whānui o te hihi oro, te koki rerekētanga hihi oro, te ōwehenga tohu ultrasonic ki te haruru, te tere oro, me te tauwehenga whakaiti.
ISO 15742: E pā ana tēnei ki te ine i te rere o te wai – ngā mita rere ultrasonic mā te whakamahi i te tikanga whakawhiti – wā mō te ine tere.
IEC 61881: E pā ana tēnei ki te pūnaha ine rere ultrasonic.
Ngā Paerewa ā-Motu
Ko te GB/T 18653 i Haina te paerewa ā-motu mō ngā mita rere ultrasonic.
Ko te JJG 1030 te ture manatoko mō ngā mita rere ultrasonic i Haina. E whakarato ana i ngā whakaritenga hangarau taipitopito, ngā tikanga manatoko, me ngā tukanga mō te manatoko i ngā mita rere ultrasonic.
Ngā Paerewa Motuhake mō te Ahumahi
SY/T 6143 i roto i te umanga hinu me te hau māori: E pā ana ki te kōwhiringa me te tāutanga o ngā mita rere ultrasonic, e whakarato ana i ngā aratohu mō te whakatikatika i ngā mita rere ultrasonic e whakamahia ana i roto i tēnei umanga. I roto i te umanga hinu me te hau, e hiahiatia ana e te Pūrongo a te American Gas Association Nama 9 (AGA – 9) te whakatikatika rere mō ngā mita katoa e whakamahia ana mō te whakawhiti pupuri.
I roto i te mara o te tuku wai me te rerenga wai, kei reira anō ngā paerewa ahumahi e tika ana hei ārahi i te whakatikatika i ngā mita rere ultrasonic, pērā i te whakaritenga whakatikatika ipurangi mō ngā mita rere ultrasonic, e tika ana mō te whakatikatika ipurangi o ngā mita rere ultrasonic mō te ine i te rere o ngā wai paipa kua kati i roto i te awhe tere rere o (0.3 – 10) m/s.
Hei tāpiritanga, ko ētahi atu paerewa, pērā i te ISO 17025, e whakamārama ana i ngā whakaritenga whānui mō te pūkenga o ngā taiwhanga whakamātautau me te whakatikatika, e pā ana hoki ki te whakatikatika o ngā mita rere ultrasonic.
