IOT RETROFIT DEVICES (2G TO 4G)

Retrofit 4G smart meter modems for 2G migration

Our 4G LTE smart modems provide a future-proof migration path to the LTE network with the same functionality on higher data speed. We offer our 4G devices with the same outfit, 2G fallback compatibility for retrofit purposes.

The modem forms part of the AMI (Advanced Metering Infrastructure) of a public utility company. Suitable for remote meter readout, meter data download, and remote configuration for provider’s request by schedules or on-demand.

Our smart meter modems are fully compatible with the most popular electricity meters (Landis+Gyr, Itron, Elster, Honeywell, Saphir, PME-PMI), designed to fit under the terminal covers.

NB-IOT DEVICES

NB-IoT Devices: modems, routers, and signal transmitters

Narrowband IoT is a fast-growing industrial Low Power Wide-Area Network (LPWAN) technology classified as a 5G technology, very well suited for applications that require small data transfers over a long time. NB-IoT devices consume less power that allows for longer battery life (10 years).

Advantages of NB-IoT:

  • great indoor coverage
  • support for a huge number of connections
  • extended battery life
  • reasonable price

WM Systems has years of experience in developing NB-IoT devices. We offer a wide range of M2M product for this cellular network: smart meter modems, routers, transmitters

INDUSTRIAL IOT ROUTERS, DCUS

CDMA 450 / 3G / 4G / LTE Cat.M / Cat.NB wireless industrial IoT routers, data concentrators

DIN-rail mountable, versatile M2M & IoT MBus routers, DCUs with 1-4 Ethernet ports and expansion options (as RS232/RS485, MBus, wireless MBus, MODBUS, digital/analog inputs, pulse signal reception).

Our IoT and smart metering related devices are using the OpenWRT system with easy to configure web interface and optional Device Manager sofware.

DATA CONCENTRATORS

Data concentrator devices for industrial, metering tasks

Data concentrators or DCUs have an important role in industrial automation, for example smart metering. They collect data from multiple sources and periodically transfer them to a central database.

A data concentrator is the backbone of a modern Automated Metering Infrastructure (or AMI).

Our data concentrator units (DCU) are capable of reading data from industrial systems, having wired outputs (impulse or RS485/ModBus RTU). The data transmission is done through wired RS485 connection or wireless mobile network (2G / 3G / LTE / Narrow Band). Our products are capable of continuously collecting the digital signals from max. 8 connected metering- or industrial devices.

Cost-effective solution for counting the impulse signals of the consumption meter devices (as water, gas, electricity meters) or readout status of the connected inputs.

Our data concentrators can be connected to any kind of measurement system. They reply for the incoming Modbus RTU requests through the RS485 port to an external modem. (Useful for transparent ModBus RTU data sending by a modem to a SCADA system.) It was specially made for industrial usage, measurement data collection, and automated remote metering.

INDUSTRIAL MODBUS MODEMS

Industrial IoT and Modbus modems to provide transparent RS485 Modbus communication with PLC-SCADA connection

Our portfolio of industrial cellular modems provides wireless data transmission and remote access for all kinds of industrial IoT applications like vending machines, smart metering, video surveillance etc.

Available for 2G, 3G, 4G LTE, NB-IoT, CDMA etc. The PLC connected external devices are ideal and cost-effective choices for an industrial system. It is the perfect solution for monitoring transparent or Modbus TCP/RTU communication.

This product family shares important basic features like low power consumption, control via AT commands, reliable power supply, RS485, high-quality manufacturing standards.

SMART METERING MODEMS

Industrial & Commercial Smart Metering Modems: remote meter readout with CDMA 450 / 2G / 3G / 4G / LTE Cat.M / Cat.NB data transmitting modems.

The heart of any remote meter reading solution is a modem that reads consumption data from the meters and sends it to a central server.

Our smart meter modems are designed specifically to be fully compatible with the electric meters of flagship manufacturers (Elster, Honeywell, Itrón, Landis+Gyr, PME-PMI, SAPHIR, EMH).

The software satisfies the provider’s requirements, the cases are designed to fit under the terminals covers, the power consumption of the modem is optimized for the specific meter etc.

Smart electricity metering has never been so easy! Our modems can be integrated into any AMR/AMI solution.

We also offer product customization for our clients.

WATER METERING DEVICES

Consumption water metering: Automated remote Meter Readout by pulse signal counters with NB-IoT data transmitting capability.

The heart of any remote meter reading solution is a modem that collects, counts the incoming consumption pulse signals from the connected meters and sends the consumption data it to a central server.

Our smart water meter modems are designed specifically to be fully compatible with the pulse-capable water meters of flagship manufacturers.

The devices have battery powered, long-life, independent operation with security features.

Smart water metering has never been so easy! Our devices can be integrated into any AMR/AMI solution.
