HRL-c-G3

Radio | Radio Module

Application

The HRLc G3 radio module integrates LoRaWAN^® technology for remote reading solutions.
HRLc G3 can be easily clipped onto all modular Diehl Metering meters in the inductive range (Ha+Ti or Ti) equipped with a grey or red ring. HRLc G3 has a built-in inductive sensor that makes it insensitive to magnetic fraud.
Furthermore, it can be used with any pulse-emitting meter when combined with our IZAR BE PULSE interface.

Features

Compact radio transmitter for mechanical water meter
Designed for LoRaWAN^® fixed networks (operated or private)
Available in 868 MHz
Main Functions: Midnight index, Hourly consumption, Return flow volume, Minimum and maximum flow values
Main Alarms: Fraud, Battery, Blocked meter, Temperature, Backflow, Overflow, Leak
Insensitive to magnetic fraud
Battery lifetime up to 15 years
IP 68

HRL-c-G3

Operating principle

HRLc G3 includes an electronic circuit that collects the data coming from a Diehl Metering water meter and transmits all the meter information every 12 hours in LoRaWAN^® fixed network mode.

LoRaWAN^® fixed network:
Data are collected through the operated network to which the customer has subscribed or through a private network specifically deployed by the customer. Depending on the needs of each customer, it is possible to access the data either via the IZAR@NET 2 software or directly via the network operator interface (usually REST or MQTT API interfaces).
