The KOBOLD VKM flowmeters and switches fill an important gap in the high viscosity media measurement arena. Using KOBOLD’s patented viscosity compensation system, these instruments are essentially insensitive to viscosity and density changes during operation. This development in flow and measurement control technology has resulted in an extremely versatile device usable in many applications where standard technologies have been inconsistant or otherwise have failed.
