Āe. Ka taea te whakauru ngāwari i ngā mita rere ultrasonic ki roto i ngā pūnaha PLC, DCS rānei mā roto i ngā putanga tohu ahumahi paerewa me ngā kawa whakawhitiwhiti kōrero.
Ko te nuinga o ngā mita rere ultrasonic e tautoko ana i ngā kōwhiringa putanga maha, pērā i te putanga anaro 4–20 mA, te putanga pāorooro, te putanga whakaata (whakaoho), me te whakawhitiwhiti matihiko RS485. Mā ēnei atanga ka taea te hono atu ki ngā PLC, ngā pūnaha DCS, ngā kaitatau raraunga, me ētahi atu taputapu whakahaere, aroturuki rānei.
Mō te whakawhitiwhiti matihiko, ka tautokohia e ngā mita rere ultrasonic te kawa Modbus RTU i runga i te RS485, ka taea ai te tuku raraunga pono i te wā-tūturu i ngā tawhiti roa. Ka taea te pānui tika i ngā taurangi tukanga matua pēnei i te tere rere inamata, te rere katoa, te ahunga rere, me te tūnga tātaritanga e te PLC, e te DCS rānei.
Ko te putanga anaro 4–20 mA e whakamahia ana mō te aroturukitanga rere tonu i te wā tūturu, ko ngā putanga pātere ia e tika ana mō te whakakotahitanga rere, mō ngā tono puranga rānei. Ka taea te whirihora i ngā putanga tuku mō ngā whakaoho, pērā i te rere nui, te rere iti, ngā tohu hapa pūnaha rānei.
Mā te whakauru i tētahi mita rere ultrasonic ki roto i tētahi pūnaha PLC, DCS rānei, ka taea e ngā kaiwhakamahi te whakatutuki i te aroturuki pokapū, te kohikohi raraunga mamao, te whakahaere tukanga aunoa, me te whakapai ake i te whai huatanga o te pūnaha. Me whakahaere te waea tika, te whirihoranga tawhā, me te tatūnga whakawhitiwhiti kōrero kia rite ki te pukapuka taputapu me ngā whakaritenga pūnaha PLC/DCS.
