Unimet Pro “WMC-NB”

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

Extremely long battery life

Universally compatible

Uses mobile network

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
IP68 rating for superior protection against water and dust

Remote monitoring via a cloud application

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

The system automatically detects and notifies users via the app in the event of water leaks, reducing potential damage and water loss.
Continuously monitors and informs users of any irregularities, such as backflow, manipulation or cable problems, enabling timely intervention
It supports remote device configuration without the need to go to the meter location
A customizable interface that allows users to configure data views to their specific needs, including options to customize data export formats

Long-lasting battery for uninterrupted connectivity

The battery ensures continuous power supply to the device, 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
The devices use intelligent energy management algorithms, including adaptive wake-up and optimized communication protocols, all with the aim of ensuring reliable and long-lasting operation.
