光電直讀水表
- 產(chǎn)品特點(diǎn)
- 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(dān)憂;
- MCU內(nèi)置EEPROM,數(shù)據(jù)安全，不用擔(dān)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。
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.
