Work with Krohne flow meters


 Aloha! The time has come to try something german this time! These pretty meters are very useful and if you need any help about them, you can reach me through the given contact form on the right!

Flow Measurement
KROHNE has unique expertise when it comes to flow measurement. And don’t just demonstrate ability with standard applications but also with applications that are demanding, requiring custom solutions. Customer orientation starts as early as research and development. Many products which are considered today’s industrial standards, were developed in cooperation with customers. Today, users around the world benefit from KROHNE innovation: Electromagnetic flowmeters with ceramic liners for highly corrosive media in chlorine chemistry. Mass flowmeters with just one straight tube – ideal for highly viscous media and low flow speeds. Ultrasonic flowmeters for custody transfer, working according to the time-offlight method. Vortex measuring devices with integrated pressure and temperature compensation. And variable area flowmeters: they established KROHNE’s business in 1921, today we can’t imagine KROHNE without them, if a local display is to ensure the redundancy and the certainty of the system.
