Quality Shield | Fuel Quality Sensor

Fuel quality analysis and product identification
  • Fuel Density ρ (kg/m³)
  • Fuel Viscosity µ (cp)
  • Fuel Dielectric constant ɛ
  • Temperature (°C)
  • Level and water interface (mm)
    with multi-parametric calculation


Quality Shield is an integrated tuning fork sensor that will directly and simultaneously measure the viscosity, density, dielectric constant, temperature of fuels.
Relying on patented tuning fork technology, the sensor monitors the direct and dynamic relationship between multiple physical properties to determine the quality, condition and contaminant loading of fuels such as diesel biodiesel, gasoline, Jet fuel, kerosene, biodiesel concentration and urea quality.
The multi-parametric analysis capability improves fluid characterization algorithms. Quality Shield provides in-line monitoring of fluids for a wide range of applications including fuel tanks, process lines and pressurized high flow conduits. A digital serial compliant protocol provides easy to connect interface to Consoles controller.
