Smart Metering Components and Hydrogen Flow Sensors

Enlit Europe 2026, taking place from 10 to 12 November 2026 at Messe Wien in Vienna, Austria, serves as an international forum for energy transition technologies and utility network modernization. At Stand B.111, Panasonic Industry Europe GmbH will present hardware and sensor architectures designed for smart metering, smart grids, energy distribution, and decentralized energy generation and storage.

Industry Applications
The presented technologies address operational challenges across water and gas utility networks, hydrogen production facilities, and solar or battery inverter systems. In green hydrogen generation, water electrolysis plants require precise gas purity verification to prevent explosive gas mixtures during startup and load fluctuations. Within municipal distribution networks, gas and water utilities utilize ultrasonic flow measurement and automated shut-off mechanisms to detect leaks and secure supply operations. In decentralized power grids, inverter systems depend on high-current switching and solid-state isolation to manage bidirectional energy flows safely.

Core Technology and System Architecture
For hydrogen generation, the hydrogen flow and concentration meter performs real-time monitoring of hydrogen, oxygen, and nitrogen concentrations during plant startup, normal operation, and fault detection. By measuring gas composition inline, the sensor architecture eliminates the need for external sampling lines, gas dryers, and separate analyzer cabinets.

For utility metering, the modular ultrasonic measurement solutions for gas and water achieve a measurement accuracy ratio of R1000, capturing low flow rates to identify network leakage. The smart gas meter architecture integrates a customizable safety printed circuit board module that controls supply valves based on predefined fault conditions. Powering these off-grid metering devices, CR-LAX lithium battery cells provide stable voltage characteristics over extended service intervals to prevent data loss and maintenance interruptions.

In electrical grid hardware, the HE power relay family functions as the main switching element in inverter applications, utilizing a high-current printed circuit board-mounted design to replace larger contactor assemblies. This is complemented by PhotoMOS semiconductor relays featuring a metal-oxide-semiconductor field-effect transistor output, which provide solid-state switching without mechanical contact wear when operated within specified electrical limits.

Deployment and Implementation
Panasonic Industry Europe GmbH supports system integrators and original equipment manufacturers by supplying pre-validated, modular hardware that integrates directly into existing utility and plant infrastructures. The customizable ultrasonic measurement modules and safety printed circuit board assemblies reduce engineering and certification phases during meter development. At the system level, these field measurement devices interface with cloud integration and data analytics platforms to transmit diagnostic parameters across utility networks.

Operational Impact and Performance Metrics
The deployment of inline hydrogen flow and concentration metering reduces plant footprint and total cost of ownership by removing auxiliary gas conditioning components while improving operational safety. In utility distribution, achieving an R1000 measurement accuracy ratio minimizes unaccounted-for gas and water volumes, while modular component design shortens time-to-market for meter manufacturers. In power electronics, PCB-mounted HE relays reduce thermal dissipation and assembly complexity, while MOSFET-based relays enable continuous predictive maintenance telemetry without mechanical degradation.
