NB-IoT Module Metering na-abụghị magnetik

Nkọwa dị mkpirikpi:

HAC-NBA abụghị magnetik inductive metering modul bụ PCBA mepụtara site na ụlọ ọrụ anyị dabere na teknụzụ NB-IoT nke Internetntanetị nke Ihe, nke dabara na nhazi nke Ningshui akọrọ mmiri mita atọ. Ọ na-ejikọta ngwọta NBh na inductance na-abụghị magnetik, ọ bụ ngwọta zuru oke maka ngwa ịgụ mita. Ngwọta ahụ nwere ikpo okwu njikwa ọgụgụ mita, ekwentị mmezi dị nso RHU yana modul nkwurịta okwu ọnụ. Ọrụ ndị ahụ na-ekpuchi nnweta na nha, nkwurịta okwu NB abụọ, mkpesa mkpu na nkwụsị nso nso wdg, na-egbo mkpa nke ụlọ ọrụ mmiri, ụlọ ọrụ gas na ụlọ ọrụ grid ike maka ngwa ịgụ mita ikuku.
