How to achieve remote automatic meter reading for multi rate electricity meters? Energy consumption measurement and factory energy management require 4G multi rate remote transmission meters.

The Qingdao Qingbiao three-phase multi rate meter adopts the DLT645-2007 protocol, which can achieve 4 rate (total, peak, flat, valley) or 5 rate billing (total, peak, flat, valley, deep valley) measurement;

In centralized installation scenarios, RS485 network wired wiring (subdivision model DTSF2026-RS485) or 4G wireless remote automatic meter reading (subdivision model DTSF2026-4G, suitable for decentralized installation, no wiring required) is applicable. Its main functions are as follows:

1: State Grid standard, dual RS485 communication ports (communication port 1 uses MODBUS-RTU protocol, no verification; communication port 2 uses DLT645-2007 protocol, even verification)

2: Specification: Mutual inductance voltage 3 * 220/380V current 3 * 1.5 (6) A; DTSF2026

Mutual inductance voltage 3 * 100V current 3 * 1.5 (6) A; DSSF2026

Direct voltage 3 * 220/380V current 3 * 10 (40) A; DTSF2026

Direct voltage 3 * 220/380V current 3 * 15 (60) A; DTSF2026

Direct voltage 3 * 220/380V current 3 * 20 (80) A; DTSF2026

Direct voltage 3 * 220/380V current 3 * 30 (100) A; DTSF2026

3: Can be charged at 4 or 5 rates (total, peak, flat, valley, deep valley);

4: Can remotely modify the time slot settings;

5:haveSuitable for all parts of the countryMinute clockmeasurefunction;

6: Can be copied and readA, B. C phaseVoltage, A, B. C phaseelectric current, A, B,Ceach otherActive power, A, B. C phasePower factorTotal active power, total reactive power, maximum active demand, and maximum reactive demand.

7: The communication protocol adopts DLT645-2007 and MODBUS_STU protocol, and the manufacturer provides open source communication protocol.

8: It can be equipped with Qingdao Qingbiao Energy Management System software to realize computer remote meter reading and mobile phone WeChat official account meter reading. All the software is self-developed, without third-party control, and can operate without faults for a long time.
