E, ho na le maemo a 'maloa a indasteri bakeng sa ho lekanya mithara ea phallo ea ultrasonic, a bohlokoa bakeng sa ho netefatsa ho nepahala le ho tšepahala ha tekanyo. Tsena ke tse ka sehloohong:
Maemo a Machaba
ISO 24192:2020: E totobatsa mekhoa le litlhoko tsa ho lekanya le ho netefatsa limithara tsa phallo ea ultrasonic. E akaretsa mekhoa ea ho lekanya, ho netefatsa, le ho hlahloba ho se tsitse bakeng sa mefuta e fapaneng ea limithara tsa phallo ea ultrasonic, ho kenyeletsoa le limithara tsa phallo ea tsela e le 'ngoe, limithara tse ngata le tse ngata. Tekanyetso e hlalosa mantsoe le litlhaloso, mekhoa ea ho lekanya, mekhoa ea ho netefatsa le ho lekanya ho se tsitse.
ISO 15155:2017: E hlalosa mekhoa ea ho lekanya litšobotsi tsa ultrasonic tsa li-flow metres tsa ultrasonic, ho kenyeletsoa litšobotsi tsa mahlaseli a molumo, litšobotsi tsa ho kenella, le litšobotsi tsa echo. Tekanyetso e akaretsa tekanyo ea litšobotsi tsa ultrasound tse kang bophara ba mahlaseli a molumo, angle ea phapang ea mahlaseli a molumo, karolelano ea lerata la ultrasound - ho - lerata, lebelo la molumo, le coefficient ea ho fokotseha.
ISO 15742: E amana le ho lekanya phallo ea mokelikeli - li-ultrasound flow metres tse sebelisang mokhoa oa transit - nako bakeng sa ho lekanya lebelo.
IEC 61881: E mabapi le sistimi ea ho lekanya phallo ea ultrasonic.
Maemo a Naha
GB/T 18653 Chaena ke tekanyetso ea naha bakeng sa li-ultrasonic flow metres.
JJG 1030 ke molaoana oa netefatso bakeng sa li-meter tsa phallo ea ultrasonic Chaena. E fana ka litlhoko tse qaqileng tsa tekheniki, mekhoa ea netefatso, le mekhoa ea netefatso ea li-meter tsa phallo ea ultrasonic.
Indasteri - Maemo a Ikhethang
SY/T 6143 indastering ea peterole le khase ea tlhaho: E mabapi le khetho le ho kenngoa ha li-meter tsa phallo ea ultrasonic, e fanang ka tataiso mabapi le ho lekanngoa ha li-meter tsa phallo ea ultrasonic tse sebelisoang indastering ena. Indastering ea oli le khase, Tlaleho ea Mokhatlo oa Khase oa Amerika Nomoro ea 9 (AGA - 9) e hloka ho lekanngoa ha phallo bakeng sa li-meter tsohle tse sebelisetsoang ho fetisetsa tlhokomelo.
Lefapheng la phepelo ea metsi le drainage, ho boetse ho na le maemo a bohlokoa a indasteri a tataisang ho lekanngoa ha limithara tsa phallo ea ultrasonic, joalo ka tlhaloso ea ho lekanngoa ha inthanete bakeng sa limithara tsa phallo ea ultrasonic, e sebetsang ho ho lekanngoa ha inthanete ha limithara tsa phallo ea ultrasonic bakeng sa ho lekanya phallo ea metsi a koetsoeng a tletseng ka har'a lebelo la phallo la (0.3 - 10) m/s.
Ho phaella moo, maemo a mang, a kang ISO 17025, a totobatsa ditlhoko tse akaretsang bakeng sa bokgoni ba dilaboratori tsa teko le tsa tlhahlobo, tse nang le tshusumetso e itseng hodima tlhahlobo ya dimithara tsa phallo ya ultrasonic.
