Intelligent centralized sub item measuring device

1、 Overview

Intelligent centralized sub item measuring deviceThrough the built-in high-precision metering module, the electricity consumption of each connected user is independently measured and accumulated. At the same time, it also has data remote transmission function, which can transmit the collected electricity data to the power management system through wireless or wired means, achieving remote monitoring and centralized management. Users can recharge and check their balance through the interface of prepaid electricity meters or mobile apps, and the electricity meters will deduct fees based on actual electricity consumption.

Intelligent centralized sub item measuring deviceWidely used in residential communities, commercial complexes, industrial parks and other places. Multi user prepaid electricity meters can also be installed in residential communities to achieve independent billing for each resident. In commercial complexes and industrial parks, this meter can help managers to more accurately record and bill the electricity consumption of enterprises and merchants.

2、 Product Features

Real time billing:The electricity meter can record the user's electricity consumption in real time and deduct fees based on actual consumption, eliminating the possibility of billing delays and missed payments in the postpaid system.

brownout:Electric meters can monitor electricity consumption in real time and allow users to check their balance at any time, thereby stimulating their motivation to save electricity and reducing energy waste.

方便管理：Managers can monitor and track the electricity consumption of each user in real-time through the software system of the electricity meter, arrange power supply reasonably, and avoid excessive load. At the same time, prepaid electricity meters also reduce the workload of property and management departments and improve management efficiency.

Preventing arrears and omissions:Users need to recharge before using electricity. When the balance is insufficient, the electricity meter will automatically shut down to remind users to recharge, thereby reducing the risk of overdue electricity bills.

Remote meter reading:The electricity meter supports remote automatic meter reading, eliminating the need for manual on-site meter reading, greatly improving meter reading efficiency and accuracy.

Electricity consumption data analysis:Electric meters can obtain real-time electricity consumption data from users, providing timely electricity information for power companies or management departments, and helping to formulate reasonable energy management strategies.

3、 Description of Featured Features

Electricity metering:Active energy metering (forward and reverse); Reactive energy metering (forward and reverse); Multiple rate active/reactive energy metering (forward and reverse).

Electricity measurement:Current (zero sequence current), voltage, active/reactive power, apparent power, power factor, frequency, 2-31st voltage harmonics and total harmonics, 2-31st current harmonics and total harmonics.

Multiple rate periods:Supports two sets of time slot tables, 4 time zones, 14 daily time slots, and 4 different rates for multi rate electricity and tiered electricity fee statistics.

Prepaid function:Remote prepaid function, pay first, then use electricity; Support multiple payment methods, which can be paid through third-party payment platforms; Credit function.

Time management control function:Each circuit can be set with its own opening and closing time, and the time periods can be set to working days and holidays. The starting time can be set, and up to 8 time periods can be set per day.

4、 Pre paid management plan for water and electricity in shopping malls, apartments, and dormitories

Energy metering and charging are mainly aimed at measuring users' electricity and water consumption, and charging based on energy consumption and corresponding unit prices.

Enterprises, parks, etc. purchase water and electricity from the power grid and water companies, and allocate, measure, and charge energy consumption to internal tenants, factories, employees, etc. in accordance with relevant policies and regulations.

Our application scope mainly includes energy consumption measurement analysis and billing services for enterprises, parks, commercial property management, etc., such as commercial real estate groups, university parks, rental apartments, chain supermarkets, etc.
