Introduction to the Smart Sensus 640C Water Meter


In an era where water conservation and management are of paramount importance, the Sensus 640C Water Meter emerges as a game-changer in the utilities sector. This advanced metering infrastructure (AMI) device is not just a tool for measuring water consumption but a comprehensive solution for efficient water management. This article delves into the cutting-edge features and significant benefits of the Sensus 640C, illustrating why it is a top choice for both utility companies and consumers.

Key Features of the Sensus 640C Water Meter

Advanced Measurement Technology: The Sensus 640C Water Meter is the highest quality and most accurate volumetric meter available at an affordable price. With a wide range of communication options, the Sensus 640C makes an ideal choice for smart water networks and NAVs in the UK.

Robust Design: Built to last, the 640C is a positive displacement (PD) mechanical meter which boasts the highest quality rotary piston meaning accuracy will be retained across its lifecycle. The meters composite body boasts a sturdy construction that is resistant to environmental wear and tear. It is designed to function optimally in a wide range of temperatures and conditions, making it suitable for various geographic locations.

Integrated Wireless Communication: One of the standout features of the 640C is its integrated wireless communication capability. It supports various communication networks like RF, cellular, and fixed network, facilitating seamless data transmission and remote monitoring.  This allows easier installation and commissioning and no external clip on module.

High-Resolution Data Logging: The meter is capable of comprehensive data logging with very granular sampling periods that enable water usage analysis, leak detection, alarm protocols and consumption pattern analysis.

Tamper Detection: Enhanced security features include tamper detection mechanisms. This ensures the integrity of the meter readings and protects against fraudulent activities.

User-Friendly Interface: The Sensus 640C Water Meter is designed with a user-friendly interface, making it easy for consumers and utility personnel to read and interpret data.
