Podczas stosowania ultrad\u017awi\u0119kowych miernik\u00f3w poziomu serii KUS z uniwersalnymi zasilaczami 220V do 24V \/ 12V, klienci napotkali dwa kluczowe problemy:<\/p>\n\n\n\n

  1. awaria komunikacji seryjnej (przerwa w komunikacji RS485);<\/li>\n\n\n\n
  2. Odchylenie pomiaru (rzeczywista odleg\u0142o\u015b\u0107 3m wykaza\u0142a wahania oko\u0142o 1m).
