Where Is The Intelligence of Smart Electricity Meters

The electric meters that we can see in our daily life seem to be similar in appearance, but in fact they have their own characteristics. Some electric meters have complete functions and can communicate with the Internet, and are suitable for high-end residences, office buildings, and factories; some electric meters have relatively simple functions and are only suitable for user areas that read data. Among them, these brands are widely used and highly recognized. What are the powerful functions of these meters? What are the advantages of smart meters? The editor of the remote power meter reading system will give you a good introduction.

1. Electric energy metering function

Active energy can be measured, three-phase power supply. If one of the phases loses power, the metering accuracy is not affected.

2. Time-of-use payment rate function

It has the function of paying the rate by time period for peaks and valleys and selects the function of dividing the time period for peaks and valleys, and the maximum rate can be set to 4.

3. Anti-theft function

It has event recording functions such as cover opening, phase failure, reverse phase sequence, zero clearing, and reverse power is included in forward power, preventing users from illegally removing or cutting off voltage and current wiring.

4. Display and storage function

Using LCD to display the power data of the past three months, it can display the total power and the A, B, C split-phase power. Can store current month, last January, last February, last March... last 12 historical monthly power data

5. Data output and communication functions

The meter can be read through the button, infrared handheld and RS485 communication port, and with the meter reading system, various power data of the meter can be read, and the communication protocol of the DL/T645-2007 multi-functional energy meter can be supported.

6. Measuring functional value

The sensitivity of the metering module is higher than that of the mechanical energy meter, and the measurement is accurate.

7. Measuring stable value

The metering stability value prevents metering loss, and the reactive power can be included in the active power.

8. Read data function

Through the hand-held infrared meter reading machine, various data of the electric meter can be read. Through the buttons on the meter, you can query the electricity consumption data of the meter on the LCD screen. Through RS-485 communication meter reading, you can read various power data and measure parameters.

9. Anti-theft electric function

If the user illegally removes or cuts off the voltage and current wiring, the meter will send an alarm signal until the user resumes normal power consumption.
