FAQ About Remote Smart Power Meter Purchases
Q1: What are the accuracy errors of the remote smart power meter?
Answer: The precision grades of commonly used smart meters are generally divided into active power 0.5S, 1, and 2. Some high-demand substations are also useful at 0.2S. The allowable error of the 0.5S level meter is within ±0.5%; the allowable error of the level 1 meter is within ±1%; the allowable error of the level 2 meter is within ±2%.
Q2: How to choose a suitable communication solution for a remote smart electricity meter?
Answer: ① The meter is installed in a decentralized manner, which is suitable for the use of GPRS solution. The meter has a built-in flow card, which can directly upload data to the system master station, no concentrator, no wiring, no distance restrictions, and easy installation. ② The electricity meter is centrally installed, suitable for the use of RS-485 scheme. The meter is connected to the concentrator with 485 wires hand in hand, and the built-in flow card of the concentrator uploads data (a concentrator can connect up to 32 meters, and the distance between the meter and the concentrator does not exceed 50 meters), which can save costs.
Q3: Can a smart energy meter be paired with a meter reading system without using a collection device?
A: The smart meter uses the 4G/NB-IoT wireless solution to eliminate the need for collection devices such as collectors and concentrators, and the meter can be directly connected to the cloud service system. If you use the RS-485 communication scheme, you need to use the acquisition equipment to connect with the system.
Q4: Can a smart meter prevent electricity theft?
Answer: Smart meters basically have the function of preventing electricity theft. The anti-theft technology of electricity meters is to prevent electricity theft by monitoring daily usage. If the usage is abnormal on a certain day, the system will feedback the abnormal information to remind, and the property owner will contact the owner or go to the site to investigate and eliminate it.
Q5: How about the quality and service life of the hour watt meter?
A: It is best to choose a first-line big brand electric meter directly supplied by the manufacturer when purchasing a smart meter. In this way, it can be guaranteed that it is genuine, the quality is also guaranteed, and the error rate is controlled between three to four ten thousandths. The normal lifespan of a smart meter today is 10 years.
Q6: Is the installation easy? Will the company provide installation?
A: The installation and wiring of the electric meter and the acquisition equipment are not complicated. An ordinary electrician can meet the needs. The general company does not recommend arranging employees to help the installation on site. Because if the employee is arranged to go there, the employee's salary, transportation, accommodation, and food will need to be added to the transaction cost, which will be relatively much higher. However, the company will arrange professional customer service to explain the installation and use details in detail.
