General Description

The VKM flowmeters and switches fill an important gap in the high viscosity media measurement regime. Using patented viscosity compensation system, these instruments are insensitive to viscosity and density changes during operation. This development in flow and measurement control technology has resulted in an extremely versatile instrument usable in almost all imaginable applications.
