NB IoT electric meter

NB IoT meters can query one's own electricity consumption on the meter by swiping an IC card, just like ordinary IC card meters, and can also achieve intelligent management of household electricity consumption through IoT technology. Including the ability to automatically store electricity usage information in the cloud and query it anytime on the computer. The management department can accurately analyze the user's electricity consumption and peak hours through the electricity consumption information collected by IoT meters, thereby improving management efficiency.

NB IoT meter function introduction:

(2.1) It has forward active energy: reverse active energy metering function, which can store its data and set combined active energy accordingly;

(2.2) It has a time-sharing metering function: active electrical energy is accumulated separately according to the corresponding time period, and the total, peak, peak, flat, and valley electrical energy is stored;

(2.3) Storage function: It can store 12 months of total electricity and electricity at various rates; The boundary time for data storage is 24:00 at the end of the month, or hourly from the 1st to the 28th of each month;

(2.4) Equipped with overdraft limit function: When the remaining power exceeds the set overdraft limit, the arrears will be triggered, and the user's electricity consumption will be temporarily suspended. The user needs to purchase electricity before resuming electricity consumption; (Can be set)

(2.5) It has a hoarding limit function. When recharging, the total amount of remaining electricity in the table and the purchased electricity cannot exceed the set hoarding limit, otherwise it will result in recharge failure; (Can be set)

(2.6) Able to measure, record, and display operating parameters such as voltage, current, power, and power factor of the current energy meter. Measurement error (citation error) shall not exceed ± 1%;

(2.7) It has a calendar and clock, and can set 2 time zones throughout the year. Within 24 hours, 8 time periods can be programmed arbitrarily; The minimum interval between time periods is 15 minutes; Time periods can be set across zero points;

(2.8) Support modifying time zone and time period tables through infrared and RS485 communication interfaces, and have security measures to prevent unauthorized personnel from operating.

NB IoT meter price reference:

1. The price of a single-phase NB IoT meter ranges from 550 yuan to 850 yuan per unit.

2. The price of a three-phase four wire NB IoT meter ranges from 850 yuan to 1200 yuan per unit.

3. The price of a rail type NB IoT meter ranges from 350 yuan to 450 yuan per unit.

NB IoT meters have specific prepaid functions, remote reading functions, resistance to high voltage and static electricity attacks, excellent harmonic functions, and anti-theft functions; The product uses imported high-quality chips with very precise measurement; Our product provides a one-stop service from production to sales. It is believed that nb iot meters will develop rapidly and steadily by taking advantage of the "Internet". Let's wait and see.
