Viscosity Meters

Viscosity Meters

Viscosity measurement and control systems are used for continuous in-line measurement and

control of viscosity ofmany liquids. Specially designed for fuel oil applications, it is used for

diesel engines on ships and in land basedpower plants. VAF Instruments expertise in this

field resulted in a unique patented, superior measuring principle;ViscoSense®.

World-market leader in fuel viscosity control

Today, VAF Instruments is world-market leader in fuel viscosity control. In the 1960's VAFalready introduced a viscosity sensor for fuel oil: Viscotherm®. From then on VAF's namefor quality, reliability and accuracy has led to the current status of world-market leader.More than 30,000 systems have found their way to ships and industrial plants all over theworld. You'll find VAF service facilities in more than 40 countries in principal harbours,industrial and shipbuilding areas of the world.

What makes ViscoSense® unique?

The VAF Instruments ViscoSense® is a viscosity sensor with a unique operating principle. The patented measuring principle is based on rotational vibration of a pendulum in liquid. The damping of this electrically controlled vibration is directly related to the viscosity. The ViscoSense® achieves the most accurate viscosity measurement possible.

User benefits

Cost saving:

optimises burning efficiency and fuel consumption.

reduces engine maintenance/overhaul costs.

no moving parts, therefore low operating costs are ensured.

the smooth edged pendulum is practically insensitive to adherence preventing local servicing costs.


no preventive maintenance required because ViscoSense® has no moving parts.

the compact light-weight construction is easy to install in new and retrofit applications.
