光電直讀水表

光電直讀水表
  • 產(chǎn)品特點
  • 采用光電透射式直讀技術(shù)，直接讀取字輪數(shù)據(jù)，無累計差;
  • RS-485 或M-bus總線制通訊技術(shù)，能夠同時給水表供電和傳輸數(shù)據(jù);
  • 總線供電，無電池壽命的擔憂;
  • MCU內(nèi)置EEPROM,數(shù)據(jù)安全，不用擔心因掉電丟失數(shù)據(jù);
  • 抄表時短時間工作，電子單元壽命長。
Product features
Adopting photoelectric transmission direct reading technology, directly reading wheel data without cumulative error;
RS-485 or M-bus communication technology, capable of simultaneously supplying power to water meters and transmitting data;
Bus powered, no concerns about battery life;
MCU has built-in EEPROM for data security, so there is no need to worry about data loss due to power failure;
Short working hours during meter reading and long lifespan of electronic units.
