Unimet WMC

WATER METERING

Compact NB-IoT device (module) compatible with magnetic and inductive indicators for direct installation on mechanical water meters of various manufacturers, models and diameters: Itron, Honeywell/Elster, Sensus, Maddalena, B-Meters, Zenner …

BASIC FEATURES

Extra long battery life

Universally compatible

Broad communication

IP68 protection

Easy installation

Advanced NB-IoT module for water meters for seamless integration

Universal compatibility with leading water meter brands

Current compatibility with a wide range of mechanical water meters.
Easy installation with interchangeable adapters, no need to purchase a pulse output and no cables between the water meter and the module
Long-lasting battery with a lifespan of up to 10 years
IP68 rating for superior protection against water and dust

Monitoring through a web application in real time

Monitoring relevant data, providing clear insight into current system performance.

The system automatically detects and immediately notifies users via the app in the event of a water leak, reducing potential damage and water loss.
Continuously monitors and informs users of any irregularities, such as backflow, magnet manipulation or cable problems, enabling timely intervention
Configuring data display according to specific user needs
The application offers a customizable interface that allows users to configure data display to their specific needs, including options to adjust the data logging and sending intervals.

Long-lasting battery for uninterrupted connectivity

Up to 10 years of operation with integrated and replaceable battery

The battery provides continuous power to the device for up to 10 years, even in demanding conditions
The integrated battery can be easily replaced without the need to lose IP68 protection, thus ensuring continuity of operation and reducing maintenance costs
Ideal for long-term projects and installations in hard-to-reach areas where frequent maintenance is impractical
