With many years of experience in meter design, our company has launched a new type of smart meter, which can communicate via RS485, NB-LOT (5G), 4G, WIFI, Bluetooth, ROLA, carrier, etc. This series of meters has the advantages of small size, high precision, good reliability, and easy installation. The performance indicators meet the technical requirements of national standards GB/T17215 and GB/17883.

DTZ series/DSZ series electric energy meter is an electronic multifunctional electric energy meter independently developed and produced by our company. This product adopts low-power large-scale integrated circuit technology and SMT advanced manufacturing technology, and has the characteristics of high measurement accuracy, stable performance, high quality, excellent EMC performance, etc. It has the functions of measuring positive and negative active electric energy, four-quadrant reactive electric energy, recording time-sharing electric energy of four rates and various events during the operation of the meter (voltage, current, power factor, load, demand, and programming events). It has infrared communication and dual-channel RS485 communication functions. It is equipped with a power outage meter reading battery, which can realize the power outage infrared meter reading function. The performance indicators of this meter meet the technical requirements of GB/T17215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters", GB/T17883-1999 "Level 0.2 and Level 0.5S Static AC Active Energy Meters" and DL/T614-1997 "Multi-function Energy Meter" for multi-function energy meters. Its communication meets the requirements of DL/T645-1997/DL/T645-2007 "Multi-function Meter Communication Protocol".
