Contactless signal capturing from the operating medium is realized through the rotation of the KEM Flow Meter’s measuring insert, offering rapid system integration combined with an operating interface and parametrization options. Modular products enable our customers to provide the required data interfaces of frequency, analog, and digital outputs. They cover the scope of performance and expectations of users in various markets and applications. At the same time, we ensure that our products comply with legal explosion protection and EMC directives.
