Wired remote photoelectric direct reading meter (RS485/M-BUS)

LD405 photoelectric direct reading remote transmission water meter is a direct reading remote transmission water meter developed by our company to meet the actual needs of daily water use, which is convenient for remote meter reading and control. It adopts M-BUS/RS485 bus communication mode to achieve remote direct reading of the water consumption of the water meter, effectively avoiding the management department’s door-to-door meter reading. This product also has valve control function (optional), which facilitates management departments to control the water usage of direct reading and remote transmission water meters, making remote meter reading and control more convenient and reliable. While saving manpower, material resources, and financial resources, it effectively improves productivity.
