IFM SUH201 - Ultrasonic flow meter SUC25IJBFRKG/US

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.
