Accurate flow measurement of ultrapure water and water
A robust, component-free measuring pipe made of stainless steel offers high media resistance and permanent ingress resistance
The highly accurate inline measurement process eliminates any influence of varying wall thicknesses and pipe materials
Operating status LED signals the sensor status and allows conclusions about process quality

Convenient operation via buttons or parameter setting via IO-Link
