ViscoSense®3D

Viscosity & Density Measurement - Enabling Mass Flow Measurement

Product Bulletin

Most of the operating costs of a ship are fuel-related. Therefore, it is very important to use fuel in the most efficient way. The Calculated Carbon Aromaticity Index (CCAI) is the index for the ignition quality of residual fuel oil and is calculated from the density and viscosity of the fuel. The measurement and control of viscosity and density ensure improved combustion efficiency, preventing engine damage and reducing fuel and maintenance costs.

Principle of operation

ViscoSense®3D is able to measure inline the actual dynamic viscosity and density of a large range of liquids. The unique measuring principle of ViscoSense®3D is based on a torsional vibration of a pendulum in liquid. The measured damping of this piezo-driven vibration is directly related to viscosity. A built-in temperature sensor measures temperature where the viscosity is measured.

Viscosity, Density, and Temperature Measurement

ViscoSense®3D is a highly accurate sensor with a superior measuring principle based on the proven ViscoSense® technology. It offers density, viscosity, and temperature measurements. Combined with VAF Instruments PT2 Flowmeters, this system is a cost-effective solution for mass flow measurement.

Viscosity Control

A large variation in the quality and composition of fuel oil makes the behavior of the fuel oil at higher temperatures difficult to predict. Optimal viscosity is needed for the best possible atomization of HFO in the engine, ensuring complete burning without remaining deposits.

Mass Flow Measurement

Fuel is generally bought in metric tonnes; hence, fuel consumption is increasingly monitored in kilograms. Smart usage of existing components of the fuel system, combined with an upgrade of the viscosity sensor, enables mass flow measurement.

For the Maritime Industry

After years of research, ViscoSense®3D, based on proven ViscoSense® technology, is specially designed for the maritime industry. VAF Instruments, a worldwide market leader in measurement and control systems, is a specialist for the maritime and process industry.

Cost-effective Solution

To enable mass flow measurement, only a small upgrade of your current fuel system is required. One ViscoSense®3D can be combined with multiple flowmeters in the same fuel system. Fuel consumption measurement by PT2 Flowmeters, combined with density measurement by ViscoSense®3D, provides a cost-effective solution enabling mass flow measurements with high accuracy, reliability, and repeatability.
