Smart Meter Reading
Traditional manual meter reading is time-consuming and laborious, and accuracy and timeliness cannot be reliably guaranteed. This leads to the failure of relevant marketing and business management software to obtain sufficiently detailed and accurate original data; general manual meter reading is performed on a monthly basis It is feasible for user metering, but it is not enough for relevant supply departments to conduct deeper analysis and management decision-making. The actual demand of the industry has given birth to the continuous development of automatic meter reading system technology and application.
