VAD Gas IoT Solution is a complete industrial IoT ecosystem for gas distribution networks. The solution covers the full chain from ATEX-certified field sensors through cabinet-level controllers and smart metering to an AI-driven cloud platform with remote valve control — all designed, manufactured and certified in the EU.

Why It Matters

Three global forces are reshaping the gas distribution market. Methane regulation is accelerating: the EU Methane Regulation 2024/1787, the US Methane Emissions Reduction Program (IRA) and the OGMP 2.0 framework all require operators to measure, report and reduce emissions with auditable data. Distribution grids are ageing: the average European network is over 40 years old and commercial losses reach 5–8% across CEE utilities. IT landscapes are fragmented: utilities run dozens of disconnected SCADA, metering and billing stacks from different vendors, with no single source of truth and no real-time control.

The Problem

Most gas utilities operate fragmented metering nodes. Over 70 different volume corrector families are deployed across EU and CIS networks — Elster, Honeywell, RMG, RMA, Itron, Dresser and dozens of local OEMs — each with its own protocol, firmware and service procedures. Readings are collected manually once or twice a year, with no anomaly detection and no real-time visibility. Shutoff valves are operated on-site, with no remote control and no digital audit trail. Regulators, operators and consumers all share the same blind spot.

The Desired Outcome

VAD transforms reactive gas operations into data-driven distribution. Manual reads of one to two times per year become hourly telemetry with full billing-grade data. Time from anomaly to valve action collapses from hours or days to under five minutes. Zero audit trail is replaced by a complete EU-compliant digital record of every reading, alert and command. Target outcomes include non-revenue methane reduction to under 2% within three years, anomaly-to-action under five minutes, and 100% compliance with EU Methane Regulation reporting.

Solution Architecture

The solution is built as one integrated ecosystem with five layers. ATEX sensors (VADTel SENS) capture pressure, temperature and leak signatures directly in Zone 1. Cabinet controllers (IIoTU3, AIIoTU8, AIoTU5, ValveLink) acquire data from any corrector or meter and drive the valve actuator. Smart metering devices (VADTEL-MT G6-G25, ECM) provide billing-grade gas volume and diagnostic data. Cellular uplink runs over GSM, GPRS and NB-IoT, with a full API reference for third-party integration. The VAD IIoT Ecosystem cloud platform aggregates, analyses and controls the entire fleet with 15 AI microservices across three pillars.

Controller Family

Four DIN-rail controllers cover every gas-network topology from the smallest node to a full regional depot.

VADTel-IIoTU3

Entry-level cellular telemetry unit for single-node installations. GSM, GPRS and NB-IoT connectivity, isolated RS-485 for one corrector, tamper input and low-power design for battery-backed nodes.

VADTel-AIIoTU8

Multi-meter DIN-rail controller with eight isolated RS-485 channels, designed for district-level cabinets. Supports all 70+ corrector protocols, pneumatic manifold control and valve drive outputs.

VADTel-AIoTU5

Five-channel controller for mixed-metering nodes. Handles gas correctors, pressure sensors and auxiliary I/O in a single housing with optional LTE backup.

VADTel-ValveLink

Valve-control unit for remote shutoff. Drives pneumatic or electric actuators, reads position feedback, interfaces with ATEX barriers for Zone 1 deployment and logs every operation to the cloud audit trail.

Smart Metering

VADTEL-MT G6-G25

Smart gas meter with micro-thermal measurement — no moving parts. Three flow ranges cover residential to commercial metering. Measures pressure, temperature and volume simultaneously, reports over GPRS or NB-IoT (optional LoRaWAN and RS-485), runs on a dual-battery architecture with > 6 years metrology and up to 10 years telemetry, and includes a built-in solenoid shut-off valve. MID-certified (2014/32/EU) to EN 1359 and EN 12405 for fiscal use.

Metering Node Cabinet

The VAD metering node cabinet is a complete field-deployed assembly that integrates every component required for remote gas metering and valve control. Cabinet contents include the ValveLink controller, Ex ib intrinsic-safety barriers for Zone 1 sensor lines, GSM antenna for cellular uplink, 12/24V battery supply, pneumatic drive compressor, solenoid valve manifold, actuator position board, upstream and downstream pressure sensors and RS-485 external correctors. Typical deployments include gas distribution nodes, regulator stations, district reduction points and remote valve chambers.

Cloud Platform

VAD IIoT Ecosystem

The VAD IIoT Ecosystem is a centralized cloud platform for monitoring, control and analytics across the entire deployed fleet. The platform manages over 100,000 devices across 10+ countries, with multi-tenant architecture and role-based access control. Four core pillars: live fleet status and map view, trend analytics and historical archive, valve operations with audit trail, and compliance and regulatory reports. Full API reference available for third-party integration.

AI Microservices

15 AI Microservices in 3 Pillars

The platform includes 15 AI microservices organised into three functional pillars. Detection covers leak-signature analysis, pressure-anomaly detection, tamper and fraud detection, meter health and drift monitoring, and network-topology anomaly. Optimisation covers non-revenue methane analytics, load balancing, pressure-zone management, dispatch routing and maintenance scheduling. Forecasting covers demand prediction, battery-life forecasting, asset lifecycle modelling, emission reporting and capacity planning. The analytics view provides calendar-heatmap readings, communication-session statistics and battery voltage trends per node.

Remote Shutoff Workflow

Anomaly → Valve Close — with a Complete Audit Trail

Remote valve control operates as a three-step guarded workflow. Detect: the SENS edge AI or the platform identifies an anomaly — pressure drop, leak signature, tamper. Confirm: the operator reviews context, verifies role-based permissions and optionally requires dual approval. Execute: ValveLink closes the actuator, position is sensed in real time, and every event is written to the audit log. The full sequence from anomaly detection to valve close runs in under five minutes.

Scale and Languages

One architecture serves every scale. Tier 1 (National): one platform with federated tenancy for national operators and multi-region holdings. Tier 2 (Regional): 10,000+ metering nodes per regional DSO or TSO. Tier 3 (Depot): 1,000 nodes per district depot or city operations team.
