Multi function energy meter refers to the watt-hour meter which has more than two functions, such as time-sharing and measurement demand, in addition to measuring active power (reactive power), and can display, store and output data, and has powerful data acquisition and processing functions. Digital multifunction meter is suitable for all common power parameters, real-time power measurement, energy measurement and power quality analysis in power grid. The user-friendly operation method of Acrel multifunction meter manufacturer provide digital multifunction meter that more convenient to use, if you want to know more about multi function meter price and other info, please contact us.
When the digital multi function meter is working, the voltage is divided by the resistance, and the current is sampled on the sampling resistor by the current transformer, and then sent to the dedicated power chip for processing, and converted into a digital signal to the CPU for calculation. Due to the use of a dedicated power processing chip, the voltage and current sampling resolution is greatly improved, and there is enough time to measure the power more accurately so that the measurement accuracy of the electric energy meter has been significantly improved. Smart energy meter application is more and more wide.
The CPU in the figure is used for time-sharing billing and processing various input and output data, reads the data of the dedicated energy chip through the serial interface and completes the time-sharing active energy metering and maximum demand metering functions according to the preset time period. According to the needs, display various data, communicate through infrared or RS485 interface, and complete the monitoring of operating parameters, record and store various data.
