He aha te akomanga tika o te mita wai ultrasonic?

Ngā akomanga tika omita wai ultrasonickua wehea ki te Akomanga 1 me te Akomanga 2.

1. Mō ngā mita wai Akomanga 1 (e pā ana ki ngā mita wai me te Q3​≥100 m3/h anake), i roto i te awhe pāmahana wai mai i te 0.1∘C ki te 30∘C, ko te hapa mōrahi e whakaaetia ana mō te mita wai i te rohe rere nui (Q2​≤Q≤Q4​) he ±1%; ā, i te rohe rere iti (Q1​≤Q
2. Mō ngā mita wai Akomanga 2 (e pā ana ki ngā mita wai me te Q3<100 m3/h, ā, e pā ana hoki ki ngā mita wai me te Q3≥100 m3/h), i roto i te awhe pāmahana wai mai i te 0.1∘C ki te 30∘C, ko te hapa mōrahi e whakaaetia ana o te mita wai i te rohe rere nui (Q2≤Q≤Q4) he ±2%; ā, i te rohe rere iti (Q1≤Q
