Smart Water Meter Modules: LoRaWAN and NB-IoT
Add-on smart modules turn standard cold and hot water meters into remotely read metering points. The module is mounted on the meter, sealed, and sends readings over a LoRaWAN or NB-IoT network — no manual meter rounds, no cables. Built-in magnet and removal sensors report tampering, and the service life is at least 20 years.

Why Upgrade Water Meters with Smart Modules
In today’s world, keeping track of water usage shouldn’t feel like guesswork. Whether you’re managing an apartment building, a commercial property, or a municipal network, accurate and timely information about consumption makes all the difference. At Jcom-iot, our smart modules transform ordinary water meters into intelligent tools that deliver real readings without replacing the meters themselves.
How the Module Works
The module is installed on a universal cold or hot water meter in a place specially designed for it and then sealed. It reads the meter automatically and transmits data to your metering, monitoring or dispatching system. If someone applies a magnet or removes the module, the sensors register the event and send an alarm.
Meter → smart module → LoRaWAN gateway or NB-IoT operator network → network server / IoT platform → billing or dispatching system.
LoRaWAN-Enabled Communication Modules
These compact add-ons attach to universal cold and hot water meters, turning them into remotely readable devices. Data flows automatically over long distances with very low energy use — ideal for basements, pits, or large residential complexes where cables are impractical. Once installed, you receive regular updates straight to your dashboard or phone, no manual visits required.
NB-IoT Water Meter Modules
NB-IoT modules transmit readings directly through the mobile operator’s NB-IoT network, so no gateways, repeaters or local infrastructure are required. This makes them a practical choice for utilities, housing operators and Smart City projects with thousands of meters, including meters in basements and meter shafts.
Which to Choose: LoRaWAN or NB-IoT?
- Choose LoRaWAN if you already have or plan your own LoRaWAN network, the meters are concentrated in one area, and you want no recurring SIM fees.
- Choose NB-IoT if meters are spread across a city, there is good operator NB-IoT coverage, and you do not want to install gateways.

الأسئلة الشائعة
Which water meters are the modules compatible with?
The modules are designed for universal cold and hot water meters and are installed in a place on the meter specially designed for the module. Separate versions are available for SVK water meters.
Do I need a gateway?
For the LoRaWAN module — yes, a LoRaWAN gateway and network server are required. The NB-IoT module connects directly to the mobile operator’s network and needs only a SIM card.
How long does the battery last?
The modules have a built-in 3.6 V lithium battery and a service life of at least 20 years.
What happens if someone tries to tamper with the meter?
Each module has a magnetic exposure sensor and a module removal sensor. Tampering events are recorded and transmitted to the monitoring system.
Can the data be sent to our own billing or SCADA system?
Yes. Data goes to a LoRaWAN network server or through the NB-IoT operator network to your platform, and from there to billing, monitoring or dispatching systems.
