PRODUCT OVERVIEW

Intelligent Metering for Modern Grids

The i310 (DTZ1513) is a high-precision, industrial-grade three-phase smart meter designed by Inhemeter for complex power distribution networks. Featuring a modular communication architecture, it leverages RF Mesh technology to ensure bulletproof connectivity in dense urban and remote industrial environments.

Designed for both prepayment and post-payment applications, this meter offers exceptional anti-tamper features, real-time event pushing, remote load control, and multiple display modes to satisfy diverse utility requirements. Its directly-connected design eliminates the need for external CTs and PTs in standard installations.

High Protection Degree

IP54 rated for harsh industrial environments with optional IP65 upgrade.

Modular Design

Hot-swappable modules for RF/PLC/GPRS/3G/4G/NB-IoT communication.

Smart Event Detection

Real-time event pushing for immediate asset protection and response.
