2.1 SYSTEM DESCRIPTION
ViscoSense
®
3 is, besides other applications, intended for use in fuel oil treatment systems to obtain a
correct measurement and control of the fuel oil viscosity.
Figure 1 shows a typical fuel treatment system with return line from the engine. In this system, the
degassing/mixing tank operates as a fuel buffer, ensuring gradual changes of viscosity which results
in a stable control of the viscosity. The ViscoSense
®
3 sensor is used to measure the actual viscosity
of the fuel oil. The signal from the sensor is compared to the setpoint of a viscosity controller, which
regulates the output of the fuel heater via a control element (steam or thermal oil valve, or electric
heater cabinet).
