IIoT telemetry module
VADTel IIoTU3
Compact industrial telemetry module for cellular and LPWAN-connected monitoring of remote field equipment.
Industrial-grade build
CE-certified hardware engineered for long-term unattended operation in field cabinets and substations.
Multi-protocol gateway
Combines wired sensor buses with cellular IoT to bridge legacy metering into the VAD IIoT Platform.
Secure end-to-end
TLS-encrypted MQTT, signed firmware updates, and per-device credentials.
The VADTel IIoTU3 module is the workhorse of the VADTel telemetry family. It is designed for industrial deployments where a single device must aggregate readings from multiple meters and sensors, run local logic, and stream the data to a central platform over cellular networks.
Typical deployments include gas pressure-reduction stations, electrical substations, district-heating nodes, and remote pumping stations across the EU and CIS regions.
