R400 Ultrasonic Smart Water Meter – Accuracy Technical Specifications
The ultrasonic smart water meter uses the time-of-flight ultrasonic metering principle. It calculates flow velocity and volume by measuring the time difference between ultrasonic signals traveling downstream and upstream. The R400 turndown ratio (Q3/Q1=400) is the key accuracy feature of this meter. It extends the minimum measurable flow, reduces the low-flow dead zone, and is ideal for residential fiscal metering and billing.
DLMS Smart Gas Meter – Simplify Gas Consumption Management
How much gas have you used? How much balance is left? Is the gas meter operating normally? Our DLMS smart gas meter supports remote meter reading, historical gas consumption inquiry, event logging and valve control. It delivers transparent gas usage data and streamlines daily service operations for gas utilities.
DLMS/COSEM acts as a universal communication protocol** between gas meters and management platforms. It enables standardized data transmission for reliable data reading, identification and centralized management.
Technical Specification of Electric Meter Communication Board Drag
The electric meter communication board is one of the core components of smart electricity meters. It is mainly responsible for data acquisition, local communication and remote network interaction. Serving as the connection bridge between the metering module of the electricity meter and the external management system, it forms the hardware foundation for smart grid implementation, remote meter reading and prepaid management. This communication board supports two mainstream communication modes: **RS485 wired communication** and **wireless remote communication**, to meet deployment requirements of various application scenarios.
Smart Gas Meter Data Security and Encryption Technologies
Smart gas meters enable remote meter reading, online recharge, and remote valve control. At the same time, they are vulnerable to risks such as data theft, tampering, and forgery. Therefore, data security and encryption technologies have become an indispensable part of their technical architecture.
