Patent ID: 8128279

Claim:
A cloud point monitoring system, comprising: a pumping device configured to pump diesel fuel therefrom in response to a voltage being applied to the pumping device; a temperature sensor configured to generate a temperature signal indicating a temperature of diesel fuel in the pumping device; a viscosity sensor configured to generate a viscosity signal having a characteristic indicative of a viscosity level of the diesel fuel in the pumping device; and a controller configured to generate the voltage to induce the pumping device to pump diesel fuel therefrom, the controller further configured to determine a temperature value based on the temperature signal, the controller further configured to determine a cloud point temperature value associated with the diesel fuel based on the temperature value and the characteristic of the viscosity signal, wherein the viscosity sensor comprises a current sensor configured to generate a current signal indicative of an electrical current in the pumping device, and wherein the controller is further configured to monitor the current signal to determine a time interval associated with the electrical current that the pumping device utilizes to pump diesel fuel therefrom, the time interval being the characteristic indicative of the viscosity level of the diesel fuel, the controller configured to set the cloud point temperature value equal to the temperature value when the time interval is greater than or equal to a threshold time interval value.
