Product overview
The iES-M100 wired remote gas meter has functions such as automatic metering, valve control and M_BUS communication. Photoelectric direct reading technology is adopted to read the current indicated value directly, and the reading accuracy is 100%. It can not only improve the meter reading rate of gas companies, but also solve the safety problem of gas users.
Functional characteristics
u Photoelectric direct reading: directly read the value indicated in the window, with an accuracy rate of 100%.
u M-BUS bus technology: two-core cable, no distinction of positive and negative pole.
u Passive design: There is no power supply in the meter, and the meter reading device will supply instantly during the meter reading.
u Anti-magnetic function: The meter usually does not supply power and is not affected by magnetism.
u Valve control function: The meter realizes outdoor remote valve control.
