What makes us tick: We Live quality at GWF

Innovation and digitalization

GWF has been investing in the development of new technologies, products and business models and in the digitalization of our processes for years. With customized solutions, we help our customers become more digital and take advantage of modern measurement technology and data processing.

Our brand

The GWF brand goes back to our original name as «Gas- und Wassermesserfabrik Luzern». Today, we still manufacture, refurbish and calibrate gas and water meters at our founding site in Lucerne. As GWF we are proud of our history and at the same time focused on the future.

Swiss market

We have been active in our home market of Switzerland since 1899. In recent years, we have developed from a manufacturer of leading measurement instruments into a system integrator with a broad portfolio of products and solutions for the energy, water and building technology sectors.


We are internationalizing our business by establishing GWF sales and service offices and our global network of long-term distribution partners. We are active as a component and technology supplier for other manufacturers and providers of complete system solutions. In 2022 we were nominated for the Switzerland Global Enterprise Export Award.


It is impossible to imagine the modern energy mix without hydropower. Our measuring devices are used to monitor the efficiency of the turbines online and to optimize the processes for this important energy source. They are thus an essential building block for sustainable operation.

Water supply

In water supply, we offer measurement devices both in the supply network and at the end user. We have various technological solutions - from the proven battery-free encoder water meter «MTKcoder®» to the award-winning ultrasonic flowmeter «Sonico®».

Water as a resource is our passion and we care about the future of our planet. That’s why we combine our innovative measurement technology with easy-to-use software and maintain a global network of leading water management experts to provide solutions to specific water challenges around the world.
