Meter reading modules, which read the meter and transmit the data to water management offices, can't use the electric wires for their power supply. Therefore, batteries have to be used for meter reading modules and that cause maintenance problems like periodic batteries replacement. To save the maintenance cost, a wireless transmitting solution with less power consumption is required. In This paper, we designed a remote meter reading module, which reads meter automatically with less power consumption of battery by effective management of power source and transmits the reading data using RF.

This paper proposes an advanced digital kwh-meter, which records voltage management data, load management data as well as the existing kwh data. This meter supports the requests from DRMS (Distribution Remote Management System) which include kwh meter reading, voltage management data reading, and load management data reading request, it can enhance greatly the economics of the existing remote meter reading system. Also it can improve highly the quality of power supplied to the electric customer by minimizing the voltage management cost and by enhancing the efficiency of load management.

This paper has studied a remote AMR(Automatic Meter Reading) system using the power line and the telephone line as a communication media and the digital power meter. In the developed system, because we have used the power line and telephone, the facility is very easy and then its cost is not expensive. The system includes following elements: a digital power meter, an indoor communication system using a power line modem and a telephone line interface system for sending data to the utility company.

This paper presents the AMR (Automatic Meter Reading) system using the binary CDMA (Code Division Multiple Access) radio technology. The binary CDMA is the new radio technology in domestic research. Main implementation topics includes the binary CDMA remote meter reading system, the wireless piconet configuration for the wireless automatic meter reading, and the transmission scheduling for sending and receiving data. Also, the wireless packet data encryption is very important topics for the wireless automatic meter reading. The proposed AMR system is implemented as a pilot project in Jeju and Gangwon. It can be seen that the wireless remote reading using the binary CDMA wireless technology can be applied to the AMR system.

This paper is related to remote meter-reading using magnetic sensor. Scan system which is developed recently has week point of temperature, humidity, dust, oscillation To solve these problems, this study used magnetic action to measure the consumption of gas. Gas consumption was detected by interaction of a permanent magnet and hall element. Permanent magnet was pasted on rolling change-gear in normal gas meter and hall sensor was pasted on the external wall of normal gas meter. This experiment proved high accuracy and wasn't influenced by temperature, humidity, oscillation and dust

In this paper, we propose a LoRa communication module using the LoRa RF module of Murata Electronics is designed to configure the IoT digital meter remote meter reading and a method of configuring a remote meter reading network by collecting multiple meter data in a DCU (Data Concentrate Unit) to configure a network with LoRaWAN. The developed system can be installed more easily and economically in the network configuration than the existing system by allowing the meter to be directly connected to the network or matched with a DCU to connect to the network according to the configuration of the consumer. The developed system was constructed using a digital water meter as an example, but it can also be applied to remote meter reading of the metered values of other meters such as electricity, water, gas, hot water and calorie meters. The main development contents are the design, configuration, and construction of digital meters, LoRa modules and DCUs, and how to connect the LoRaWAN network and transmit meter data to the server. By networking these devices, the system is configured, and the actual LoRaWAN communication is tested and the result is shown.

In this paper, we present measurement method of the amount of used piped water and the communications environment for automatic piped water meter reading. The existing piped water meter reading which is carried out by the human in person by monitoring the amount of use and recording make the problem of an error of the figure and being short of staffed to carry out piped water meter reading. To solve the existing problem in this paper, the amount of used piped water is converted into data type by Photo Interrupt Sensor, and IEEE 802.15.4 Protocol is used to confirm the measurement in remote place.
