VISCOSITY IN LINE ANALYSERS

COMP 2-ViscoSenseViscosity measurement and control systems are used for continuous in-line measurement and control of viscosity of many liquids. Specially designed for fuel oil applications, it is used for diesel engines on ships and in land based power plants. VAF Instruments expertise in this field resulted in a unique patented, superior measuring principle; ViscoSense®.

Why Viscosity is an essential parameter for Ship Efficiency?

A large variation in the quality and composition of fuel oil, makes the behavior of the fuel oil at higher temperatures difficult to predict. An optimal viscosity is needed for the best possible atomization of HFO in the engine, so the fuel will be burnt completely without remaining deposits. The measurement and control of the viscosity ensures an improved combustion efficiency, preventing engine damage and reduces cost of maintenance. Viscosity control contributes to a green environment.

Viscosity Control for fuel saving and ship efficiency

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. A built-in temperature sensor is used to measure the temperature at the same location where viscosity is measured. ViscoSense®2 is able to measure inline the actual dynamic viscosity of a large range of liquids. Due to the operating principle based on a torsional vibration, the measurement is insensitive to unwanted external influences.

Flow velocity, flow direction and pulsations have no effect on the sensor operation.

The robust built sensor is designed to operate under the most difficult conditions in which a faultless and stable viscosity measurement is required.
