Pre-paid watt-hour meters are also called quantitative watt-hour meters and IC card watt-hour meters. In addition to the ordinary watt-hour meter's metering function, in particular, users first buy electricity and then use electricity after buying electricity. , It will automatically cut off the power and stop the power supply.
With the increase of residents' electricity consumption, the application of pre-paid energy meters is becoming more and more widespread. What are the main features of pre-paid energy meters? Below, Shandong University of Technology Zhongtian Xiaobian will explain to you:
1. There is no need to initialize the settings when newly installing and replacing direct reading water meters.
2. The entire system does not need any power supply during normal work, and only needs to provide power instantly when reading the meter, and the data is never lost.
3. When the signal line has an open or short circuit fault, it does not affect the accuracy of the data. When the line returns to normal, the collected data is still consistent with the current counting value of the water meter.
4. For use in wet water meters, the unique patented sealing technology scheme is used to seal the sensor and the character wheel in a transparent character wheel box, which can be used in different water quality, which ensures that the reading of the water meter is permanently clear and electronic. The sensor part works stably and reliably for a long time.
5. There is no cumulative error in data collection, and there will be no garbled characters when carrying round characters.
6, not affected by external voltage, light source, high and low frequency, magnetic field, water pressure and other environmental factors.
