Wireless Energy Meter System manufacturers DescriptionWireless AC Power Meter is a tool for measuring voltage, current and other data. It can be used as a watt-hour meter, and it's its working principle is the same as single-phase watt-hour meter, they have different structures. In addition, it is small, anti-interference and stable, so it has a long service life. In addition, we have added a current value sampling mode to facilitate the installation and operation of the meter in different applications. This wireless power meter can be simply installed in the distribution box for the purpose of power sub-metering and energy monitoring in various areas where the load varies. It is a versatile product that can be used in small businesses, public utilities, residential buildings, etc. FeaturesWireless AC Power Meter use Hall sensors to achieve non-contact current, so you don't have to disconnect wires, which has the advantage of safety, reliability and convenience. Secondly, our products have dual relay interfaces to manage discharge and charge separately. Most importantly, our power off has memory function, after power off and power on again can remember the number of AH and WH indicators before power off. 1. The Wireless AC Power Meter has a built-in 4G wireless communication module, which can realize many communication functions, so it can be connected to the Internet without collecting equipment. 2. The installation of the product is flexible, and it can realize sub-item electric energy metering and monitoring. 3. The LCD can display a variety of important information for easy recording. 4. It can aggregate data over long distances.
