The right module for every field measurement.
I‑METS 20, 70 and 90 read electricity, water and natural gas meters in the field; I‑METS 80 also controls the valve over the same network. All four share the same LoRaWAN® 868 MHz network and the same OSOS Platform — OSOS's own engineering, from the PCB to the embedded software. For bulk M‑Bus metering projects, the family extends with the I‑METS 30 RS‑232/USB/Repeater converter and the I‑METS 50 datalogger, which collects data remotely over 2G/3G, WiFi, Ethernet or RF without needing a fixed IP. This same network is extended into inaccessible sites by the WIFX L1 4G gateway, adding a 4G backhaul connection — a Swiss-made product that OSOS distributes in Turkey.
Electricity Meter Module
Plugs directly into the electronic meter's optical port; the meter is not removed, the seal is not broken, and the subscription record does not change. Installation is completed in seconds, and the meter connects to the LoRaWAN® network within seconds.
UMM‑250 M‑Bus Converter
An industrial converter that opens up to 250 meters on a single M‑Bus line for reading. Connects to a computer or an I‑METS 50 datalogger via RS‑232, USB or Repeater interfaces; the communication lines carry short‑circuit, overvoltage and ESD protection.
MBus Datalogger
A standalone data collector that reads M‑Bus meter groups over 2G/3G, WiFi, Ethernet or RF and resolves the telegrams internally — no fixed IP or server required. Readings are sent as CSV files by email or to an FTP server, and every record is also backed up on the unit's own SD card.
LoRaWAN Water Meter
The mechanical measuring mechanism and the LoRaWAN communication module are combined in a single body. It combines MID-approved measurement accuracy with wireless data transmission; the battery life is designed to run in the field for years without maintenance.
Electronic Valve
The family's only "action" module. It reads water, gas and calorimeter meters with dry pulse output, and remotely opens/closes the valve over the same LoRaWAN® network. The other three modules only read — I‑METS 80 applies the decision-support output directly in the field.
Natural Gas Module
Mounted on top of the existing natural gas meter; has an ATEX-certified housing suitable for explosive atmosphere classification. The motion sensor tracks consumption on the mechanical display contactlessly and transmits it via LoRaWAN®.
4G-Backhauled LoRaWAN Gateway
A fully self-contained base station that backhauls a LoRaWAN® network over the 4G cellular network at sites with no fiber, ADSL, or fixed line. OSOS is the Turkey distributor for WIFX, the Swiss manufacturer; it shares the same 868 MHz LoRaWAN network as the I‑METS modules — opening up network coverage at inaccessible points for rural utility sites, solar power plants, and agricultural projects.
Which module, for which measurement.
All four share the same 868 MHz network and the same OSOS Platform — the difference lies in the measurement type and role.
