Environment & Sustainability

KEM is committed to sustainable environmental protection. We put this into practice by ensuring that every KEM employee uses all resources along the value chain carefully and sparingly – even beyond the require-ments of legal regulations. KEM develops, manufactures, and produces its products with the goal of impacting the environment as little as possible and not endangering people.

In addition, we support the further expansion of green power plants with our flow meters.

Our processes and procedures are subject to regular reviews and continuous improvement.

    Application

    Wind energy is used all over the world as a clean energy source. Glass fiber and carbon fiber composites have become established as materials for the rotor blades of wind turbines. These combine essential characteristics such as high strength, low weight and long service life.
    The rotor blades are not molded in one piece. The top and bottom sides are each cast separately and then joined together to form a unit by a bonding process. Adhesives made of glass fibre, carbon fibre, silicone and other composite materials are used. These are highly viscous and abrasive. The aim is to achieve a fast and sustainable bond – a challenge for measurement technology. Even the smallest errors can lead to serious additional costs.

      Solution

      KEM Helical Flow Meters (SRZ Series) withstand extensive abrasion forces and provide accurate measurement data even at high viscosities. A special metrological bearing concept ensures precise measurement results, high reproducibility and long service life.
