KOBOLD’s VKG series viscosity-compensating flowmeters and switches fill an important gap in the high viscosity media measurement field. Using KOBOLD’s patented viscosity-compensation system, these instruments are largely 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 many viscous media applications.
